Definitions

  • the invention relates to shoes with an outsole formed by injection molding or the like, the shaft of which is connected by means of a seam to an insole covering the outsole and has an outwardly pointing lower edge which is trimmed after the outsole has been formed.
  • it relates to a process for the production of such shoes, the upper being sewn together from appropriate blanks, the insole then being sewn onto the upper and finally the outsole being formed after the shoe upper thus produced has been produced.
  • the invention is based on the object of proposing a design for shoes with a molded outsole which does not have the aforementioned deficiencies of the prior art, i.e. in particular, ensuring a clean line-up, leads to reliable adhesion of the outsole to the shaft and enables the shoe to be finished in a simple manner after the outsole has been molded on.
  • the insole in the shoe according to the invention only extends as far as the transition between the shaft and the edge strip projecting outwards.
  • the sole has been cast on, only the upper leather then has to be trimmed in the shoe according to the invention, which can be done in a simple manner and with comparatively light tools.
  • the insole only extends to the transition point between the upper and the shaft has the advantage that the dimensions of the insole correspond exactly to the underside of the last.
  • the shoe can be used to spray the barrel very precisely sole, since the operator on the machine has the option of orienting himself precisely on the edge which usually exists on the underside of the last and delimits the sole surface. It is only necessary to align the outer edge of the insole with this edge on the last. This is particularly facilitated if the insole is made of easily bendable, only slightly stretchable material, since this would show the last edge of the last in the wrong way.
  • the use of the very flexible insole also has the advantage that overall you get a very well and easily bendable shoe bottom, which was not always the case with the previously known shoes in flexible design, especially because of the usually comparatively large thickness the midsole, but also because of the frequently used gluing between the outsole and midsole.
  • the shoes according to the invention therefore differ from the shoes known hitherto on the one hand by considerably better and more precise processing, on the other hand by their particularly good flexibility, and there is also the possibility of saving a relatively large amount of material for the midsole, since an insole is normally also added anyway is used.
  • the insole can be made from different materials. Particularly good wearing properties is obtained if the insole is made of leather and has a non-stretchable or slightly stretchable support, preferably made of textile material, on the underside, which is expediently connected flat to the insole.
  • a decorative seam running at the same distance from the outer edge of the lower edge and penetrating only the shaft is provided on the lower edge of the upper, along which a special seam for fixing the insole on the upper runs.
  • a decorative seam is easy to apply, gives an appealing look to the shoe and at the same time can be used in a simple manner as a marker for sewing in the insole.
  • the decorative seam With an appropriate arrangement of the decorative seam, it is covered on the underside by the cast-on outsole, so that there is no risk of water penetrating in the region of the seam.
  • the wearing comfort of shoes according to the invention can be improved in that - in a manner known per se - an insert, for example made of felt, fleece or the like, is inserted into the injected outsole directly below the insole.
  • This insert can, however, come into its own particularly well in the shoe according to the invention, because usually an easily bendable insole is provided.
  • the molded outsole can be provided with bulges or depressions forming a footbed on the upper side, which are produced in a simple manner when the outsole is cast on. For this it is only necessary to provide corresponding recesses or protrusions on the underside of the last used during the casting.
  • the shoe according to the invention can be produced in various ways, the shaft always being sewn together from appropriate blanks, then the insole sewn onto the shaft, and finally the outsole is molded on after the shoe upper thus produced has been produced.
  • a special manufacturing method is now proposed, which is characterized in that, before the insole is fastened, the - sewn-together - shaft with a transition point to the outwardly pointing lower edge, always running at the same distance from the edge of the lower edge Provide the decorative seam or marking and then the insole is sewn with its peripheral edge along this decorative seam or marking on the upper, and that when the upper of the shoe is subsequently attached, the upper is aligned with the last so that the peripheral edge of the insole runs along an edge of the last on the sole side .
  • such a procedure has the advantage that the decorative seam or marking can be precisely namely depending on the edge of the lower edge, can be generated because the edge of the lower edge is predetermined by the die cut with appropriate accuracy.
  • the insole can then be stitched in very precisely along the resulting decorative seam or marking.
  • the quilted insole, in conjunction with the edge on the underside of the last, provides reliable help for a clean listing of the shoe upper for spraying, so that the molded-on sole sits precisely and almost exactly on the upper or shaft on all shoes.
  • the shoe according to the invention comprises a conventional upper 1, which is removed on the underside by a sewn-in insole 2 is closed, an insert 3, for example made of felt, fleece or the like, and a cast-on outsole 4.
  • the upper 1 is provided with an outwardly facing lower edge 5 which, in the exemplary embodiment shown, has two decorative seams 6 which only penetrate the lower edge 5. It can be relatively coarse seams.
  • the insole 2 is only so large in the shoe according to the invention that its peripheral edge 7 comes as close as possible to the transition point 8 between the actual upper 1 and the lower edge 5. It is sewn along its circumferential edge 7 by means of a seam 9 in the transition region 8 between the upper 1 and the lower edge 5, the seam 9 (as can be seen in FIG. 2) in the region of the outside of the shoe covering the inside of the decorative seams 6 as precisely as possible.
  • the insole 2 consists of a material that is as soft as possible, but not stretchable, for example it is produced in two layers from an upper leather layer and a lower layer made of non-stretchable material, for example textile material, whereby the lower layer can be connected to the upper leather layer.
  • the cast outsole 4 has a footbed on the upper side is provided. Only one protrusion 10 serving as a pad is shown in the drawing.
  • the edge 5 of the upper 1 in the shoe according to the invention comes in direct contact with the material of the molded or molded outsole 4 in the region of its underside 11.
  • the outsole 4 in the area of the underside 11 of the edge 5 can be connected securely to the edge 5 and thus to the shaft 1 without difficulty.
  • the underside 11 of the edge 5 is usually roughened from the house, since it is usually the Aass side.
  • the underside 11 of the edge 5 may be sharpened or provided with an adhesion promoter order
  • the midsole according to the invention has no midsole.
  • its flexibility is significantly increased compared to the known flexible shoes with molded outsole and also improves the adhesion between the shaft and outsole, which was done in the known shoes only over the seam between the midsole and shaft.
  • the upper 1 is finished by sewing its individual stamped parts together, the edge 5, as shown in FIG. 1, being kept wider than would be necessary with regard to the finished shoe (FIG. 2).
  • at least one decorative seam 6 - possibly also only one marking - is then applied to the shaft 1 parallel to the outer edge 12 of the edge 5; a decorative seam can, for example, be quilted easily by means of a foot with a stop.
  • a suitably punched or cut-out insole 2 is then sewn along the circumferential edge 7 into the now sewn, modeled upper, in such a way that the seam 9 runs exactly along one of the decorative seams 6, which in this case serves as a marking, or along a special marker is placed.
  • the upper upper part produced in this way consisting of upper 1 and insole 2, is then pulled onto the last 13 (FIG. 1), which has recesses 14 or projections on its underside which correspond to the desired footbed.
  • the last 13 which has recesses 14 or projections on its underside which correspond to the desired footbed.
  • the upper part of the shoe which is now listed is then inserted into a corresponding shape which, according to FIG. 1, consists of two laterally movable side parts 16, 17, a vertically movable bottom part 18 and two side holders 19 and 20, respectively.
  • the movement of the molded parts is such that the base part 18 moves upwards into the position according to FIG.
  • the outsole material for example a polyurethane or PVC foam material, is then injected or poured into the mold cavity 21 via a line (not shown), where it is cured or, if necessary, allowed to foam.
  • the insert 3 Before inserting the last 13 with the shoe upper consisting of the upper 1 and the insole 2, the insert 3 can also be placed on the underside of the insole and fixed in any way, for example by means of an adhesive connection, which is only punctiform. As soon as the outsole 4 is correspondingly hard, the mold is opened. It is then only necessary to cut off the portions of the edge 5 projecting beyond the outer edge 22 of the sole 4, for example by means of a knife, in order to complete the shoe.
  • the outsole 4 can of course be designed as desired, for which purpose it is only necessary to shape the walls of the mold cavity 21 accordingly.
  • the outer edge 22 of the sole can be profiled without the risk of damage, because after demolding only the relatively thin and soft, protruding strip of the edge 5 of the shaft 1 has to be cut off.
  • the form shown is of course shown purely schematically. The exact design of the shape will depend on the respective shaft and sole design.
