Definitions

  • the invention relates to a shoe sealing system and a sealing method for a sealed shoe with a shaft and an insole to which the shaft is connected.
  • a waterproof layer Lining the upper of the upper with a waterproof layer.
  • This is preferably a waterproof, water vapor-permeable functional layer, by means of which waterproofness while maintaining breathability, i.e. Permeability to water vapor is achieved.
  • the functional layer is often part of a functional layer laminate which, in addition to the functional layer, has at least one textile layer.
  • Shoes of this type are either equipped with a functional layer in the form of a so-called bootie, which covers the entire
  • a sealed shoe according to the invention has a shaft and an insole to which the shaft is connected, with reactive hot-melt adhesive based on polyurethane being applied and pressed flatly on the underside of the shoe in the area of the insole and the shaft part connected to it.
  • a method for the production thereof is also provided, in which the upper is connected to the insole and is applied and pressed flatly onto the underside of the shoe in the area of the insole and the upper part of the upper connected to the insole and bonded thereto. Embodiments of this are given by the dependent ones
  • a shoe according to the invention is on the bottom of the shoe in
  • the bottom of the shoe means the underside of the shoe before applying an outsole.
  • Reactive hotmelt adhesive is an adhesive that leads to water resistance in the fully reacted state. In a shoe according to the invention, this causes the seal in the area of the sole structure.
  • open-pore, adhesive-friendly material is applied over the entire shoe and the side area or in parts thereof.
  • An upper material such as leather, fleece, felt or the like is preferably used as such material. This material is preferably in the reactive
  • Hot melt adhesive glued flush. This means that the surface of the upper material which points away from the insole is essentially flush with the surface of the reactive hot-melt adhesive which points away from the insole. In this way, that the bottom of the shoe (in the sense defined above) has a flat and uniform surface, which, for example, makes it easier to glue a running sole.
  • the sole part of the upper of the shoe is connected to the insole by lasting adhesive. That is to say, a lasting area of the sole part on the sole of the sole, which is drawn over the edge of the insole on the underside thereof which points to the later outsole, is fastened to a peripheral region of the underside of the insole by gluing.
  • the reactive hot melt adhesive is then applied to the bottom of the shoe (in the sense given above) in order to seal the bottom of the shoe before applying an outsole.
  • Hot melt adhesive overlapped by a width of about 1 cm between the insole and the pinched shaft. This ensures that the inner circumference of the lasting fold is securely sealed by the reactive hot melt adhesive.
  • the reactive hot-melt adhesive is applied to the entire underside of the insole not covered by the lasting fold and to the mentioned overlap region with the lasting fold.
  • Pinch gluing process can be used without modification.
  • To maintain the water resistance in the area of the sole structure only the reactive hot-melt adhesive needs to be used Outsole to be applied to the bottom of the shoe. The water resistance is therefore achieved with very little additional effort.
  • Reactive hot-melt adhesives are adhesives that, before they are activated, consist of relatively short molecular chains with a medium one
  • Crosslinking leads to a particularly strong protection against the penetration of water into the adhesive. This highly effective seal and protection against the ingress of water are of particular importance in the area of sole construction.
  • Polyurethane reactive hot melt adhesives hereinafter referred to as PU reactive hot melt adhesives, are particularly suitable for the purpose according to the invention.
  • EP epoxy resin
  • the curing reaction of the PU reactive hot-melt adhesive which causes the curing is usually brought about by moisture, for which air humidity is sufficient. There are blocked PU reactive hot melt adhesives whose crosslinking reaction only takes place after the activation of the
  • PU reactive hot melt adhesive can begin by means of thermal energy, so that such hot melt adhesive can be stored open, ie in an environment with atmospheric moisture.
  • non-blocked PU reactive hot melt adhesives in which one Crosslinking reaction takes place at room temperature if they are in an environment with air humidity. The latter hot melt adhesives must be kept protected from atmospheric moisture as long as the crosslinking reaction is not yet to take place.
  • Both types of PU reactive hot melt adhesives are usually in the form of rigid blocks in the unreacted state. Before applying to the areas to be glued, the hot melt adhesive is heated in order to melt it and thus make it spreadable or coatable. In the case of using unblocked
  • Hotmelt adhesive must be heated in the absence of atmospheric moisture. This is not necessary if blocked hot melt adhesive is used, but care must be taken to ensure that the heating temperature remains below the unblocking activation temperature.
  • PU reactive hot melt adhesive is used which is built up with blocked or blocked isocyanate. To overcome the isocyanate blocking and thus to activate that built up with the blocked isocyanate
  • Reactive hot melt adhesive must be thermally activated. Activation temperatures for such PU reactive hot melt adhesives are approximately in the range from 70 ° C. to 170 ° C.
  • the crosslinking reaction can be accelerated by the application of heat.
  • a PU reactive hot melt adhesive is used, as described under
  • Designation IPATHERM S 14/242 is available from HPFuller in Wells, Austria.
  • a PU reactive hot melt adhesive is used, which is under the name Macroplast QR 6202 is available from Henkel AG, Düsseldorf, Germany.
  • a material is said to be waterproof if it has a water entry pressure greater than
  • the measurement is carried out by exposing a sample of the material to be examined with an area of 100 cm 2 to an increasing water pressure.
  • distilled water with a temperature of 20 + 2 ° C is used.
  • the increase in water pressure is 60 ⁇ 3 cmH 2 O / min.
  • Water inlet pressure of the sample corresponds to the pressure at which water occurs on the opposite side of the sample.
  • the exact method for performing this test is described in ISO Standard No. 811 from 1981.
  • Whether a shoe is waterproof can e.g. be checked with a centrifuge assembly of the type described in US-A-5,329,807.
  • the textile fabrics can be, for example, woven fabrics, knitted fabrics, knitted fabrics, fleece or felt. These textile fabrics can be made from natural fibers, for example from cotton or viscose, from synthetic fibers, for example from polyesters, polyamides, polypropylenes or polyolefins, or from mixtures of at least two such materials.

  • viscose e.g. a viscose, fleece available under the trade name Texon, e.g. Polyester fleece, to which melt fibers can be added, leather or glued leather fibers.
  • a lining material is normally arranged on the inside of the upper material for the shaft.
  • the same materials are suitable for this, as previously specified for the upper material.
  • an outsole is applied to the underside of the shoe.
  • This can consist of waterproof material such as rubber or plastic, for example polyurethane, or of non-waterproof material such as leather in particular.
  • the bonding of the reactive hot-melt adhesive to the underside of the shoe becomes particularly intimate if the reactive hot-melt adhesive is mechanically pressed against the underside of the shoe after being applied to the underside of the shoe and thus pressed.
  • a pressing device e.g. in the form of a pressure pad, with a smooth material surface that cannot be wetted by the reactive hot melt adhesive and therefore does not stick to the reactive hot melt adhesive, for example made of non-porous polyterafluoroethylene (also under the trade name
