Description

Footwear with sealed sole structure and manufacturing procedure

The invention relates to a system of shoe sealing and a sealing procedure for a shoe sealed with an instep and a template to which it is attached at the instep, and in particular with an instep that is equipped with at least partially of a water-tight function layer, which preferably it is permeable to water vapor, and with a sole, in particular a sole stuck. In addition, the invention relates to a procedure for the manufacture of such a shoe.

Background of the invention

There are shoes that are waterproof in the area of instep, for example, by coating the upper material of the instep with a waterproof layer. In this case it is preferably of a water tight function layer, permeable to water vapor, by means of which the water tightness is achieved water maintaining breathing activity, that is, water vapor permeability. The function layer is usually part of a function layer laminate that next to the layer of Function has at least one textile layer.

Special efforts are necessary to ensure a lasting water tightness in the area between the end of the instep on the side of the sole and the structure of the sole.

To achieve this, parts have been used sock type inserts, also called circle booties of experts, between the instep and the sole structure by a side and an inner lining on the other side. Since such booties they are shaped by welding cut pieces to size, not They need to present sewing holes. The use of booties, without However, it is very complicated in manufacturing, when the booties in in a certain way they must correspond to the shape of the respective shoe.

Another known method is to seal the area bottom of the shoe structure, and with it the lower area of the instep coated with the function layer and eventually sewn to a template, with the sole material of an injected sole. But with this the water in the upper material cannot be prevented of the instep, which conducts water in general because of capillarity, reach the end of the instep on the side of the sole and with it at the end of the function layer on the side of the sole and through water bridges, particularly in the form of textile fibers in the cutting edge of the instep end of the side of the sole, reach the inner lining that is on the inner face of the function layer and that generally absorbs water very intensely

These problems have been resolved with a sole structure known from EP 0 298 360 B1, in which in the area of the end of the instep of the sole side, the Function layer has a projection with respect to the upper material, which is saved with a network band, a face of which is sewn fixedly to the upper material and the other side to the function layer and to the template. Thus, the projection of the function layer is sealed by the sole material that during the injection, in which it is liquid, has penetrated the network band. Regarding water, which has advanced along the upper material to below the instep end area on the side of the sole covered by the sole, the network band represents a block, particularly when it is a band of monofilament net, so that such water cannot advance to the cutting edge of the function layer of the side of the sole and therefore not even the inner lining of the footwear.

This network band solution has proved very effective. Since this case the sealing of the final area of the function layer of the sole side involves the injection of a sole, this known method is limited to shoes with sole injected and cannot be used for shoes with attached sole. Therefore, it cannot be used for shoes with an elegant design. The injection of soles requires high costs of molds that entail a long repayment time and presuppose manufacturing costs per correspondingly high piece of the respective shoe type and of the respective shoe size.

Shoe structures are known in which the Function layer in the end area of the sole side presents also a projection with respect to the upper material, in which however there is no network band. Therefore, the material of the sole in the area of the projection is injected directly to the layer of function. Also these methods are only suitable for footwear with injected sole.

From document DE 44 33 870 A1 it is known in the lower end of the shoe instep provided with a membrane waterproof, water vapor permeable glue a sole with adhesive soles to get a seal between the edge of cut of a mounting hem, sole and insole, of so that between this cutting edge, the insole and the sole is applied a heat sealable adhesive sealing mass with shape of cord before sticking the sole.

Summary of the Invention

With the invention a shoe is provided which is it can be waterproof with relatively simple means and Little deployment

In addition, a shoe is provided with the invention in which the final area of the instep of the sole side, in case of discretionary soles, can be made waterproof durable with the least possible deployment and with the least number possible procedural steps.

A sealed shoe according to a first aspect of the invention features an instep and a template to which the instep, in which on the lower area of the shoe in the area of the template and instep piece attached to it is applied in laminar form and pressed reactive fusion adhesive based on polyurethane. According to the invention, a manufacturing process, in which the instep is attached to the insole and on the underside of the shoe in the area of the template and instep piece attached to it is applied so laminating and pressing reactive fusion adhesive based on polyurethane. Ways of realizing it are indicated in the dependent claims.

In a shoe according to the invention, on the face bottom of the shoe in the area of the insole and the piece of instep attached to it is applied in a laminar form and pressed polyurethane-based reactive fusion adhesive.

The underside of the shoe in this context is refers to the underside of the shoe before placing a sole.

As for the reactive fusion adhesive it is of an adhesive that in a reacted state leads to tightness the water. This, in the case of a shoe according to the invention produces the sealing in the area of the sole structure.

In the case of an embodiment of the invention is applied over the entire shoe and the area of the lateral or in parts of it an open pores material that hit well. As such material a material is preferably used top like leather, veils, felt or similar. Preferably, this material is glued flush to the reactive fusion adhesive. This means that the upper surface of the upper material that points out the template with the upper surface of the reactive fusion adhesive pointing out the template They are essentially flush with each other. This way you get the lower side of the shoe (in the sense defined above) present a flat and uniform top surface, which for example facilitates the stuck from a sole.

In an embodiment of the invention, the instep piece of the shoe on the sole side is attached to the template by gluing assembly. That is, a hem area for mounting the instep piece on the side of the sole worn on the edge of the template by its lower face pointing to the sole posterior is fixed by sticking to a contour area of the face bottom of the template. After the assembly paste is applied the reactive fusion adhesive on the underside of the shoe (in the direction indicated above), to seal the underside of the shoe before placing a sole.

Preferably, in the case of a shoe with glued assembly, the reactive fusion adhesive is applied on a width of approximately 1 cm overlapping between the template and The instep mounted. This achieves that the inner contour of the mounting hem is securely sealed by the adhesive reagent fusion.

In an embodiment of the invention, the reagent fusion adhesive is applied over the entire lower face of the template not covered by the mounting hem and the area overlap mentioned with the mounting hem.

In the invention it is thus carried out in addition to the glued mounting with a mounting adhesive another glued shutter with reactive fusion adhesive.

For the manufacture of shoes according to the invention the assembly paste procedure can be used Conventional without modification. To get the tightness at water in the area of the sole structure is enough that the reactive fusion adhesive is applied on the underside of the shoe not yet equipped with a sole. Water tightness is it achieves, therefore, with very little additional deployment.

According to another aspect, the invention relates to footwear with an instep or with a sole structure that presents a sole, the instep being constituted by a superior material and by a layer of waterproof function, which is at least partially to the upper material by its inner face and presents an end zone of the instep on the sole side with an end zone of the upper material and a final area of function layer, the sole it is attached to the end zone of the instep, the final zone of the layer of function presents a projection that reaches beyond the final zone of the upper material and an area of adhesive closed in the contour direction of the sole of a reactive fusion adhesive, which is reacted state leads to the water tightness

According to this aspect, the invention relates to in addition to a procedure for the manufacture of footwear with the following manufacturing stages: an instep is created that is consisting of a superior material and a waterproof function layer to the water that at least partially covers the upper material by its inner face and is equipped with a final instep area of the sole side; the upper material is provided with a zone Upper material end of the sole side and function layer it is provided with an end zone of function layer on the side of the sole, the end zone of the function layer being provided with a overhang that reaches beyond the final zone of the upper material; a closed adhesive zone is applied on the projection contour direction of the sole of a fusion adhesive reagent, which in reacted state leads to tightness at Water; a sole is attached to the end of the instep.

Advantageous improvements are indicated in the dependent claims.

Both aspects can be combined advantageously with each other, that is, the reactive fusion adhesive you can cover the entire underside of the shoe and with it also the outgoing

The footwear according to the invention has an instep and a sole, the instep being constituted by a superior material and for a layer of waterproof function that covers at least partially to the upper material by its lower face and presents a final instep area on the sole side with an end zone of superior material and an end zone of function layer. The sole It is attached to the final area of the instep. The final area of the layer of function presents a projection that reaches beyond the final zone of the top material. An area of adhesive closed in the direction of the contour of the sole of a reactive fusion adhesive that in reacted state leads to the water tightness.

The shutter function, which in the case of conventional footwear of the type indicated above is achieved with sole material, in the case of footwear according to the invention, produced by the reactive fusion adhesive applied on the outgoing from the final area of the function layer, which on the one hand in liquid state before reacting has a high capacity of creep and on the other hand in reacted state leads to a high and durable water tightness. The reactive fusion adhesive It can be applied with very simple means, for example extended, sprayed or in the form of an adhesive band or a cord of adhesive, making the reactive fusion adhesive suitable for bonding by heating and with it can be fixed to the projection, before reaction and lasting bonding to the function layer that carries with it  It begins in the area of its projection.

The water tightness of the structure of the Water-resistant shoe sole with discretionary sole achieves, therefore, in a singularly easy way and with stages of Very simple procedure. The method according to the invention leads, therefore, at low production costs for waterproof shoes Water.

In an embodiment according to the second aspect of the invention, the end area of the instep extends essentially transverse to the sole tread surface (denominated in what follows also vertical extension) and goes more beyond the final area of the function layer in the direction of the tread surface through the final area of the material higher. In another embodiment of the invention, the zone end of the instep extends essentially parallel to the surface stepping on the sole (in what follows also called extension horizontal) and extends beyond the final area of the layer of function towards the center of the sole through the end zone of the upper material. The first embodiment is especially suitable for capsule shaped soles that they have an edge that rises transversely with respect to the sole tread surface. The last embodiment is suitable especially for shoes with flat soles shaped plate, as they are used in particular in elegant shoes.

In an embodiment according to the second aspect of the invention, the projection is saved by means of a tie strip, one of whose longitudinal faces is attached to the final area of the upper material and whose other longitudinal face is attached to the final zone of the function layer. In another form of embodiment of the invention there is no such salient bran.

The reactive fusion adhesive is applied either in the area of the projection directly on the function layer, if not there is a tie strip, or it is applied on the outer face of the tie strip that saves the projection, if there is a tie strip. So that in the latter case the sealing of the layer of function with the reactive fusion adhesive, is chosen for the strip of bonding a material that is permeable to the reactive fusion adhesive liquid before the reaction or made liquid.

The existence of such a tie strip allows for a side a durable water tight seal between the final zone of the function layer and the sole stuck and makes possible on the other hand that the tensile forces, which are exerted during the tension of the final area of the function layer through the last on the function layer, for example by a cord tie ("String lasting") or by means of tensioning jaws, whether directed totally or at least partially on the material superior, instead of letting them act exclusively on the less resistant function layer.

The tie strip is preferably constituted by an open network material, which is formed by material from thermoplastic net or textile material, preferably textile material monofilament The tie strip may, however, have any another form, for example being constituted with wire clips, or long stitches or large loops or structures Similar. The tie strip must mainly satisfy the function of enabling the flow of reactive fusion adhesive sufficient liquid for a durable waterproof seal of the function layer and allow the discharge of forces from the layer of function and force discharge of the function and transmission layer or division of the load between the upper material and the material of the template (in case of assembly) or cord tie (in case of "String lasting").

For footwear according to the invention it is suitable a network band of the Jaeger GmbH & Co. Brothers in Wuppertal, Germany, with article number 23851.

The invention is suitable for footwear with template or without template. In the latter case, the final zone of the function layer of the sole side is tied tightly by means of the drawstring. Thus, the final zone of the upper material is fixedly attached or stitched to the final area of the layer of function, possibly through a network band, or the zone end of the function layer and the final area of the upper material each one of them is tied tightly by means of a strap of own cord.

In an embodiment of the invention with network band, one of its longitudinal faces is joined, preferably by sewing, to the final area of the upper material and its other longitudinal face to the final area of the function layer and eventually to the template.

In a process according to the invention for the Manufacture of footwear according to the invention proceeds as follows mode. An instep is created that is made up of a material upper and by a layer of waterproof function that covers the less partially to the upper material by its inner face and is equipped with a final instep area on the side of the sole. The upper material is provided with a final area of upper material from the side of the sole and the function layer of a final layer area of function of the side of the sole, with the end zone of the function layer of a projection that reaches beyond the final zone of superior material. An area of adhesive closed in the contour direction of the sole of a reactive fusion adhesive, which in reacted state leads to the water tightness. To the final area of the instep is fixed a sole.

The adhesive of the reactive adhesive to the layer of function is especially intimate if the reactive adhesive after the application on the projection is mechanically pressed against the function layer For this, a clamping device, for example, in the form of a pad of tighten, with an upper surface of non-wettable smooth material by the reactive fusion adhesive and, therefore, that it does not stick to the reactive adhesive, for example non-porous polytetrafluoroethylene (also known under the trade name Teflon). Preferably, a tightening pad is used for this purpose. example in the form of a rubber pad or air pad, whose upper tightening surface is covered with a sheet of the mentioned material, for example polytetrafluoroethylene no porous, or before the tightening process a sheet of this type between the sole structure provided with the fusion adhesive reagent and squeeze pad.

In an embodiment of the invention, the sole is glued with conventional solvent adhesive or thermoadhesive, as for which it is for example of polyurethane based adhesives. A solvent adhesive is a adhesive that has been made suitable for bonding by solvent addition evaporable and hardens due to evaporation of the solvent. The Thermoadhesive is an adhesive, also called an adhesive thermoplastic, which is brought to a state suitable for bonding by heating and is hardened by cooling. If such an adhesive is reheating can be brought back to the state suitable for paste.

Preferably a fusion adhesive is used moisture curable reagent, which is applied on the area to stick and is subjected to moisture to react. In a embodiment of the invention a fusion adhesive is used thermally activatable and moisture curable reagent, which thermally activated, is applied on the area to be pasted and is subjected to moisture to react.

Especially simple and economical is the manufacture of shoes according to the invention using adhesive of reactive fusion that can be activated thermally and by moisture, by example water vapor, can be brought to a reaction of hardening.

Fusion adhesive can also be used foaming reagent if you want to take advantage of its high volume, which makes it especially suitable, to fill in the spaces holes and penetrate holes or cavities that can form in the network band zone.

This can cause a tightness to the especially safe water. Foaming can be achieved if the reactive fusion adhesive during application is fluidized with a gas, as for which it is, for example, a mixture of nitrogen and air

As reactive fusion adhesive are indicated adhesives that before chains are formed relatively short molecular with an average molecular weight in the range from about 3000 to about 5000 g / mol, that do not stick and, eventually after thermal activation are brought to a reaction state in which the molecular chains relatively short crosslink in long molecular chains and so They harden and mainly in a humid atmosphere. In the period of Reaction or hardening time are suitable for gluing. Behind the cross-linking hardening can no longer be activated again. Reacting produces a three-dimensional chain reticle molecular. Three-dimensional crosslinking leads to a especially strong protection against water penetration in the adhesive.

For the purposes according to the invention they are suitable, for example, polyurethane reactive fusion adhesives, resins, aromatic hydrocarbon resins, hydrocarbon resins aliphatic and polymerization resins, for example, in the form of epoxy resin.

Especially preferred are fusion adhesives polyurethane reagents, referred to below as adhesives of melting PU reagents.

The adhesive crosslinking reaction of reactive fusion of PU that causes hardening is achieved usually due to humidity, for which air humidity is sufficient. There is fusion reagents of blocked PU whose reaction of crosslinking can begin immediately after activation of the thermal reactive PU fusion adhesive, from so that such a fusion adhesive can be deposited open, that is, in an environment with air humidity. On the other hand, there are non-blocked reactive PU fusion adhesives in which a crosslinking reaction takes place at room temperature, when they are in an environment with air humidity. These Last reactive fusion adhesives should be kept protected of air humidity while the reaction should not take place of crosslinking.

Both types of reactive fusion adhesives of PU are present in unreacted state usually in form of rigid blocks. Before application on the areas to be glued, the reactive fusion adhesive is heated to melt it and with it make it extend or apply In case of employment of unblocked reactive fusion adhesive should be performed such heating excluding air humidity. If used reagent fusion adhesive blocked this is not necessary no However, keep in mind that the temperature of heating remain below the activation temperature Unlock

In an embodiment of the invention, employs PU reactive fusion adhesive, which is constituted by blocked or masked isocyanate. For overcoming blocking of the isocyanate and thereby for the activation of the fusion adhesive reagent consisting of the blocked isocyanate must be performed a thermal activation. Activation temperatures for such PU reactive fusion adhesives are approximately placed in the range from 70 ° C to 180 ° C.

In the case of another embodiment of the Invention, non-blocked PU reactive fusion adhesive is used. The crosslinking reaction can be accelerated by contribution of hot.

In the case of a practical embodiment of the method according to the invention, a fusion adhesive is used PU reagent, sold under the name IPATHERM S 14/242 of the company H.P. Fuller in Wells, Austria. In the case of another embodiment of the invention a fusion adhesive is used PU reagent sold under the name Macroplast QR 6202 from the company Henkel AG, Düsseldorf, Germany.

Especially preferred is a function layer that is not only waterproof, but also vapor permeable Water. This allows the manufacture of waterproof shoes, that despite the water tightness remain active to the breathing.

As "waterproof" it is considered a layer function, which eventually includes the seams provided in the function layer, if it guarantees a water inlet pressure of at minus 1.3 · 10 4 Pa. Preferably, the material of the function layer guarantees a water inlet pressure above of 1 · 10 5 Pa. Thus the inlet pressure of water according to a test procedure in which water distilled at 20 ± 2 ° C is applied on a sample of 100 cm 2 of function layer with increasing pressure. Pressure rise of water supposes 60 ± 3 cm Ws per minute. The inlet pressure of  water then corresponds to the pressure at which for the first time water appears on the other side of the sample. The details of the How to proceed are indicated in ISO 0811 of the year nineteen eighty one.

As "water vapor permeable" is consider a function layer when it has a coefficient of water permeability below 150 m 2 • Pa. W -1. Water permeability is checked according to the Hohenstein-Haut model. This test method It is described in DIN EN 31092 (02/94) or ISO 11092 (19/33).

You can check if a shoe is waterproof water, for example, with a centrifuge arrangement of the type described in US-A-5 329 807. A centrifugal arrangement described therein presents four baskets carrying basculantes subjects to support the footwear. With she can be checked two or four shoes or boots at the same weather. In this centrifuge arrangement, to detect points not waterproof to the footwear are used forces centrifuges that are produced by rapid centrifugation of the footwear. Before centrifuging, water is filled in the interior space of footwear On the outer face of the shoe is arranged a absorbent material such as blotting paper or a napkin of paper. Centrifugal forces exert on the contained water in the footwear a pressure that makes the water reach the material absorbent when the footwear is not waterproof.

In a water tightness test of this type, water is first filled in the footwear. In footwear with superior material that does not have enough stiffness of its own, in the interior space of the instep rigid material is available for stabilization and thus avoid a collapse of the instep during centrifuged In the respective carrier basket is paper blotter or a paper napkin on which the footwear to be checked. The centrifuge is put into rotation For a certain time. Then the centrifuge is stopped and blotting paper or paper napkin is examined for See if it is wet. If it is wet, the checked footwear has not passed the water tightness test. If it is dry, the footwear checked has passed the test and is classified as watertight Water.

The pressure exerted by the water during centrifuged, depends on the surface of the active shoe dependent the size of the shoe (inner surface of the sole), the mass of the amount of water introduced into the footwear, of the radius effective of the centrifuge and the number of revolutions of the centrifuge

Materials suitable for the function layer waterproof, water vapor permeable are in particular polyurethane, polypropylene and polyester, including polyether and their laminates, as described in the documents US-A-4,725,418 and US-A-4,493,870. Especially preferred is, however, microporous polytetrafluoroethylene, oriented (ePTFE), as described, for example, in the US-A-3,953,566 and US-A-4,187,390, and oriented polytetrafluoroethylene which is provided with means of hydrophilic impregnation and / or hydrophilic layers; see, for example, the US-A-4,194,041. Per layer of microporous function means a function layer whose size regular pore is between approximately 0.2 µm and about 0.3 µm.

Pore size can be measured with the Coulter Porometer (trade name), which is manufactured by Coulter Electronics, Inc., Hialeath, Florida, USA.

The Coulter Porometer is a measuring device which provides an automatic measurement of the distributions of pore sizes in porous media, in which the method of liquid containment (described in ASTM E standard 1298-89).

The Coulter Porometer determines the distribution of pore sizes of a sample by means of an air pressure Increased directed on the sample and by current measurement resulting. This pore size distribution is a measure of the degree of uniformity of the pores of the sample (ie a narrow pore size distribution means that there is a small difference between the smallest pore size and the largest size of pore). It is determined by dividing the maximum pore size by the minimum pore size.

The Coulter Porometer also calculates the sizes of pore for the average current. By definition, half of the current through the porous sample takes place through pores whose pore size is above or below this pore size for the average current.

If used as an ePTFE function layer, the reactive fusion adhesive during the bonding process can penetrate the pores of this function layer, which leads to a mechanical anchoring of the reactive fusion adhesive in this layer of function. This function layer constituted by ePTFE, on the face with which during the bonding process comes into contact with the reactive fusion adhesive may be provided with a thin layer of polyurethane. If PU reactive fusion adhesive is used together with such a function layer not only a mechanical union occurs but additionally also a chemical bond between the fusion adhesive PU reagent and PU layer over the function layer. This leads to a particularly intimate bonding between the function layer and the reactive fusion adhesive, so that a Water tightness especially durable.

As superior material they are suitable, for example, leather or textile surface products. As for the textile surface products can be, for example, knitting, knitting, weft knitting, veils or felt. These textile surface products can be manufactured from natural fibers, for example of cotton or viscose, of fibers artificial, for example polyester, polyamide, polypropylene or polyolefins, or mixtures of at least two such materials.

On the inner face of the upper material for The instep is normally arranged a lining material. For it is suitable the same materials that were indicated above for the upper material.

If a function layer is used, on the face Inside is normally arranged a lining material. How lining material, which is usually attached to the function layer forming a function layer laminate, the same are suitable materials that were previously indicated for the material higher. The function layer laminate may also have more of two layers, being able to find by the face of the layer of function away from the lining layer a textile front.

The footwear insole according to the invention can be made of a waterproof material, such as rubber or plastic, for example polyurethane, or of a non-watertight material water, but active breathing, as in particular leather or leather equipped with pieces of rubber or plastic. In the case of a material of sole not waterproof, the sole can be waterproof maintaining breathing activity, so that at least in places where the sole structure has not already been made waterproof by other measures, be provided with a function layer waterproof, permeable to water vapor.

The footwear insole according to the invention can be made of viscose, veils, for example polyester veils, at fusion fibers, leather or leather fibers can be added glued A template is sold under the name Texon Brandsohle of Texon Mockmuhl GmbH in Mockmuhl, Germany. The Stencils of such materials are waterproof. A template of this or another material can thus become water tight if on your upper surface or inside there is a layer of waterproof material. For this purpose, for example, it can be heat sealed one sheet with Kappenstoff V25 from Rhenoflex in Ludwigshafen, Germany. If the template must be not only waterproof water, but also permeable to water vapor, is endowed with a water tight, water vapor permeable function layer, which preferably consists of ePTFE (polytetrafluoroethylene expanded microporous). A leather insole equipped with this form is sold under the trade name TOP DRY by W.L. Gore & Associates GmbH, Putzbrunn, Germany.

Bonding of the reactive adhesive to the face bottom of the shoe will be especially intimate if the adhesive reagent after application on the underside of the shoe is mechanically pressed against the underside of the shoe. For this is especially suitable a clamping device, for example in the form of a squeeze pad, with a surface made of smooth material, not moistened by the adhesive reactive fusion and, therefore, that it does not stick to the fusion adhesive reagent, for example non-porous polytetrafluoroethylene (known also under the trade name Teflon). Preferably a tightening pad is used here, for example in shape of a rubber pad or air pad, whose upper tightening surface is covered with a sheet of mentioned material, for example non-porous polytetrafluoroethylene, or a sheet of this type is arranged before the tightening process between the sole structure provided with reactive adhesive and the squeeze pad.

Detailed description of preferred embodiments of the invention

The shoe of the first embodiment of the invention shown in Fig. 1 presents a template 1, a instep with a mounting hem 2 attached to template 1 by mounting glue and reagent fusion adhesive 3 applied on the underside of template 1 and the mounting hem 2. Thus, the reactive fusion adhesive 3 covers the entire area of the underside of the template not covered by the hem of mounting 2 and a partial area of the adjacent mounting hem 2 to this area of the template 1. In a preferred form of embodiment there is an overlap 3a of the fusion adhesive reagent 3 on mounting hem 2 in a width of about 1 cm

A shoe of this type is preferably manufactured as follows. First, template 1 is set to the underside of a last (not shown). Afterwards, a instep on the last, the contour edge of the underside of the template is provided with a conventional mounting adhesive and the mounting hem 2 is worn on the underside of the template and attached to it. Next, the adhesive is applied of reactive fusion 3 on the lower faces of template 1 and of the mounting hem 2 and pressed there, to obtain a bottom face of the shoe with a flat top surface and uniform.

This manufacturing status is represented in side elevation in Fig. 2.

On the underside of the shoe provided with the reagent fusion adhesive 3 is then applied to a sole (no represented), for example by gluing.

With the help of reactive fusion adhesive 3, makes the bottom of the shoe or the structure of the water tight The sole

The second embodiment of the invention shown in Fig. 3 shows a shoe, which matches the shoe represented in figures 1 and 2 with the exception that this provided on the lower upper surface facing towards out of template 1 of a material 4 of open pores that sticks well, that it is glued flush on reagent fusion adhesive 3. The application of this material 4 reduces the times of expected and immediate subsequent elaboration of the shoe so manufactured.

A side elevation of this corresponding shoe to Fig. 2 of the second embodiment is shown in Fig. 4, in which the glue flush with the material 4 with the adhesive reagent fusion 3 can be seen very well.

Reagent fusion adhesive 3 is applied preferably as a thick adhesive, the degree can be influenced of fluidity by the heating intensity of the melting adhesive reagent 3.

In Fig. 5 it is shown very schematically a clamping device 5 to press the fusion adhesive reagent 3 on the bottom faces of template 1 and the mounting hem 2. For this purpose a squeeze pad of the type already mentioned.

Next, for the description of the position of individual shoe components will be used Here the vertical and horizontal concepts. This refers to the representations in the figures and corresponds to the first presentation in which shoes with your sole in most cases are on a horizontal base or a lower support Horizontal of another type.

Fig. 5 shows in a representation in highly schematic cross section a third form of embodiment of a shoe according to the invention with an instep 11 which It consists of a top material 13 and a function layer 15 that covers his inner face. Function layer 15 can be part of a function layer laminate presenting the layer of function and on its inner face a layer of lining. In addition, the layer of function 15 may be provided on its outer face pointing to the upper material 13 of a textile obverse (not shown). There is also embodiments in which the function layer and the Lining are separate layers of material.

In addition, Fig. 6 shows a template 17 and a prefabricated 19 capsule-shaped sole, which is made of rubber and / or plastic. The upper material 13 and the function layer 15 they present a final zone 21 of superior material that ends vertical, that is to say transverse to the surface of the sole 19, or final zone 23 of the function layer. The final zone 23 of the layer of function has a projection 25 with respect to the final zone 21 of the top material. The projection 25 is saved by means of a band of network 27. A first upper longitudinal face of the network band it is sewn by a first seam 29 to the lower end of the final zone 21 of the upper material. A second face longitudinal lower of the web band 27 is sewn by means of a bristle stitching 31 to both the template 17 and the end bottom of the final zone 23 of the function layer 23.

On the outer face of the network band 27 is applied a reactive fusion adhesive 33 that in state reacted leads to water tightness. In a liquid state, to which the reactive fusion adhesive arrives, for example, by heating, reactive fusion adhesive 33 penetrates through the network band 27 and advances in the area of the projection 25 to the face outside of function layer 15. In the reacted state, the reagent fusion adhesive 33 seals this area of the layer of function 15 with water tightness. Preferably, the adhesive of reagent fusion 33 is applied is such an extension and quantity  which also seals the cutting edges of function layer 15 in the lower end of the final zone 23 of the function layer. Preferably, the contour zone is also sealed. of the template 17 adjacent to the final zone 23 of the layer of function and fixing seams in which the layer of function 15.

Water or other liquid that along the upper material 13 that conducts water or liquid has advanced to the lower end of the end zone 21 of the upper material, due to this sealing by means of the reactive fusion adhesive 33, cannot reach the inside of function layer 15 and with it, not even the lining of the inner side of the shoe.

Preferably over the entire inner face of the sole 19 is applied adhesive soles 35, as to which You can try conventional sole adhesive, and specifically in solvent or thermoadhesive adhesive form. In addition, on the face outer upper material 13 is applied sole adhesive 37. A manufacturing status of the shoe of the first embodiment, before the sole 19 is pressed up against template 17 to glue it to the template 17 and to the final instep area on the sole side. Thus, the sole adhesive 35 on the inner face of the edge 40 of sole capsule 19 is bonded by adhesion to the sole adhesive 37 applied over the final area of the instep.

For a better representation and clarity in the Fig. 6 and in the other figures, the distances between the components individual shoe structure shows greater than They really are. In fact, the distances between the components individual have dimensions such that after the pressure of the sole 19 against template 17, capsule edge 40 fits with sealing to the outer face of the upper material 13 and glue to the upper material 13.

Fig. 7 shows a fourth embodiment of a shoe according to the invention, which mostly coincides with the first embodiment shown in Fig. 6, but it is difference from the first embodiment in that as in the second embodiment only the final zone 21 of the material upper ends vertical, while the final zone 23 of the layer of function ends horizontally, that is parallel to the surface of stepped on the sole 19. Therefore, also the projection 25 of the area end 23 of the function layer and essentially also the band of net 27 and reactive fusion adhesive 33 run horizontally. Due to the horizontal extension of the final zone 23 of the layer of function 23, template 17 does not extend across the entire width sole of the shoe structure but its contour edge has a certain distance from the vertical part of the instep 11. Otherwise, it coincides with the first embodiment of so that in regards to other aspects of the second way of realization refers to the previous clarifications for the First embodiment.

Fig. 8 shows a fifth embodiment of a shoe according to the invention, in which both the final zone 21 of the upper material as the final zone 23 of the function layer run horizontally, which also in this embodiment leads to an approximately horizontal extension of the band of net 27 and reactive fusion adhesive 33. Such a structure of shoe allows the use of a sole 39 shaped plate, put that unlike the first and second embodiment no edging of a vertical end zone of the instep is necessary 19 by means of a capsule edge of a sole shaped capsule. For this reason, for the third embodiment a discretionary sole can be used, for example a sole of leather, as is desirable for elegant type shoes. Due to the exclusively horizontal course of the sole 39, the adhesive of soles 37 applied on the outer face of the upper material 13 it is applied on the final zone 21 of the upper material that runs horizontally.

The fifth embodiment shown in the Fig. 8 is shown in a partially perspective view cropped, but still without sole. This figure shows a last 41, on which the instep 11 is worn. Unlike Fig. 8, a separate liner layer 43 is shown on the face in Fig. 9 inside the function layer 15. Fig. 4 shows the structure of the shoe in a state in which the reactive fusion adhesive has been applied only on the underside of the network band 27, but has not yet been pressed to advance to the final zone 23 of the function layer through the network band 27.

Fig. 10 shows a shoe structure according to Fig. 9, also in a perspective representation partially trimmed, after gluing a sole 39 to the face bottom of template 17 and the bottom face of the vertical zone of instep 11. In this representation, last 41 has already been shoe removal

Fig. 11 shows in a representation in perspective a complete shoe of the fifth embodiment shown in Fig. 10, in which a part of the shoe, to illustrate where the shoe is on trimming according to Fig. 10.

Fig. 12 shows a sixth embodiment of a shoe according to the invention, which coincides with the third form of embodiment shown in Fig. 6 except that in the sixth embodiment there is no network band 27. It can be done reference, for the most part, to the preceding description with respect to the third embodiment.

In the sixth embodiment before gluing of sole 19 and before bonding with the fusion adhesive reagent 33 in the end zone of the instep there is no union between the lower end of the end zone 21 of the upper material and the lower end of the final zone 23 of the function layer and of template 17. Immediately after the application of reagent fusion adhesive 33, due to its bonding action it has a union between the final zone 21 of the upper material and the final zone 23 of the function layer, in case the adhesive of reagent fusion is applied to an extent that encompasses the lower edge of the final area of the upper material, which is not strictly necesary. After pasting sole 19 to the template 17 and the instep 11, the final zone 21 of the upper material is fixed  laterally also by means of the sole capsule edge 40 19.

The seventh embodiment shown in the Fig. 13 coincides with the sixth embodiment shown in the Fig. 12 with the only exception that the final zone 21 of the material upper is fixed to the outer face of the function layer 15 by fixing adhesive means 43. This provides more handling Easy instep 11 during the manufacturing stages before glued to the sole 19.

The eighth embodiment of the invention illustrated in Fig. 14 shows a shoe structure that matches with that of the fourth embodiment according to Fig. 7 except that there is no network band. Regarding the coincidences with the fourth embodiment, reference may be made to the explanations regarding Fig. 7. As in the case of the sixth embodiment shown in Fig. 12, also in the eighth embodiment, reactive fusion adhesive 33 is applied directly on the outer face of the projection 25 of the final zone 23 of the function layer, which leads to a sealing paste particularly good of the final zone 23 of the function layer by the reactive fusion adhesive 33.

Corresponding to the sixth form of embodiment in Fig. 12, also in the sixth embodiment in Fig. 14 there is no fixation bond between the area end 21 of the upper material and the outer face of the layer of function 15. The final zone 21 of the upper material is adjusted, by therefore, before bonding by means of reactive fusion adhesive 21 or before gluing the sole 19 simply loose to the face outside of the function layer 15.

Fig. 15 shows a ninth form of embodiment, which represents a modification with respect to the eighth embodiment shown in Fig. 14, since the final zone 21 of the upper material is fixed by means of adhesive fixing 43 to the outer face of the lower end of the area vertical of function layer 15, before the other manufacturing stages, specifically the sewing of the area final 23 of the function layer to template 17, the application of reagent fusion adhesive 33 and sole bonding 19. So In addition, as regards the seventh embodiment, it refers to the preceding clarifications regarding the figures previous.

The tenth embodiment of the invention shown in Fig. 16 coincides with the fifth embodiment shown in Fig. 8 with the exception that there is no band of net. Therefore, it can be referred mostly to previous explanations regarding Fig. 8. Also in the case of the tenth embodiment, the reactive fusion adhesive 33 it is applied directly to the outer face of the projection 25 of the final zone 23 of the function layer, if possible with a extension such that also the end of the horizontal end zone 21 of the upper material, the contour edge of the template 17 and the bristle stitching 31 are integrated in the seal by the adhesive of reagent fusion 33. In this embodiment there is no bonding of fixing between the function layer 15 and the final zone 21 of material higher.

The eleventh embodiment shown in the Fig. 17 coincides with the tenth embodiment shown in the Fig. 16 except that the final zone 21 of the upper material it is fixed by means of a fixing glue 43 to the outer face of the final zone 23 of the function layer.

Fig. 18 shows as the twelfth form of embodiment of the invention a shoe without insole or without insole in the represented area of the shoe. There are shoes that through one part of its length, for example in the area of the previous part of the foot are formed without template and in the remaining part of the shoe with insole.

Since the shoe or part of the shoe shown in Fig. 18 there is no template, the components of the area vertical of the instep, specifically the horizontal end zone 21 of the upper material and horizontal end zone 23 of the layer of function must be held differently in position horizontal. For this, a cord tie 45 (known in expert circles also under the expression "String lasting "), by means of which the final zone is tied tightly 23 of the function layer. The cord tie 45 has a tunnel 49 drawstring with a loop that runs around the entire inner contour of the final zone 23 of the function layer, in the that a string 51 is found, by means of which it can be tied strongly the final zone 21 of the function layer, while the instep is tensioned by means of a last (not represented in the Fig. 18).

In this embodiment, a network band 27 it is sewn on a longitudinal face to the final area 21 of the upper material and the other side longitudinal to tunnel 49 of cord strap 45, so that the protrusion 25 of the end zone 23 of the function layer is saved by the network band 27 and the final zone 21 of the upper material remains horizontal. Adhesive adhesive is applied to the lower face of the web band 27 reactive fusion 33 which in reacted state leads to a waterproof seal of function layer 15 in the region of the final zone 23 of the function layer. Melting adhesive reagent 33, therefore, has, if possible, a dimension such that in its sealing the cord straps 45 and / or the seam 49 between the web band 27 and the end zone 31 of the material higher.

After application of the fusion adhesive reagent 33 is attached a sole 39 plate-shaped by means of the sole adhesive 37 to the underside of the horizontal region of the instep. Although not shown in Fig. 18, also in this embodiment can be applied adhesive soles on the lower face of the final zone 21 of the upper material before the sole is attached 39.

Fig. 19 shows a thirteenth form of embodiment of the invention, which coincides with the twelfth form of embodiment depicted in Fig. 18 with the exception that no It presents a net band, but a second cord strap 47, for means of which the final zone 21 of the upper material is tied strongly in horizontal position. In that embodiment, the reagent fusion adhesive 33 is applied directly to the outer face of the projection 25 of the final zone 21 of the layer of function.

The second cord strap 47 has a tunnel 49 drawstring, which runs around the entire inner contour of the final zone 21 of the upper material and in the that a cord 51 is found, by means of which the final zone 21 of the upper material can be tied tightly, while the instep is tensioned by means of a last (not represented in the Fig. 19).

The reactive fusion adhesive 33 is applied, by so much, with such a dimension that its shutter also integrates cord straps 45 and 47.

In Fig. 20 an auxiliary for manufacturing in a very schematic representation, specifically a clamping device 53, by means of which the reagent fusion adhesive 33 can be pressed in a state liquid or made liquid against the outer face of the final zone 21 of the function layer. This is represented in Fig. 20 specifically for a shoe structure according to the fourth form of embodiment shown in Fig. 7, but it can also be used also for all other embodiments described.

After the reactive fusion adhesive 33 has been applied and eventually taken to a liquid state by activation, is pressed by means of the clamping device 53 in the direction of the final zone 23 of the function layer, to ensure a particularly intimate bond of reactive fusion adhesive 33 to the outer face of the function layer 15 in the final zone 23 of the function layer, which is especially preferred in the forms of realization of the shoe with net band, to ensure that sufficient reactive fusion adhesive 33 advances to the surface top of the function layer 15.

The clamping device 53 may have a flat capsule shape as shown in Fig. 20, or have another form different from that represented in Fig. 20, which may depend on the shape of the respective shoe structure. The clamping device 53 can also be made as squeeze pad, for example, in the form of a pad rubber or an air pad, that is, a pad full of air At least the upper surface of the device tighten 53, which during the tightening process comes into contact with reactive fusion adhesive 33, is made of a non-material wettable by reactive fusion adhesive 33, and which is not stick to this one. A tightening device is especially suitable 53 with an upper surface of polytetrafluoroethylene (also known under the trade name Teflon), which has a smooth top surface and not a porous top surface like Microporous tetrafluoroethylene, expanded suitable for the layer of function. Thus, the upper surface of the device itself tightening 53 is composed of such material, or before the process of squeeze a sheet of such material between the structure of the sole of the footwear and the clamping device 53.

Fig. 21 shows in a representation two-dimensional schematized, not real scale, greatly enlarged, a fragment of a sole structure with fusion adhesive reagent 33 reacted by three-dimensional chain crosslinking molecular (in which the seam that joins the final zone 23 of the function layer and template 17 is not represented). The three-dimensionality of crosslinking occurs because the chains molecular reactive fusion adhesive 33 also in the third  dimension (transverse to the top surface of the drawing) no visible in Fig. 2 crosslink in the form represented for two dimensions. Three-dimensional crosslinking leads to protection  especially strong against water penetration in the adhesive.
