The invention relates to a multi-layer material which can be used for the division of shoes in the trimmed state as a brajido hollow material.

As a binding (> d av / iochan shaft and outsole (shoe substructure) hat the insole for the quality and the properties of use high-quality shoes are of particular importance. Experience has shown that durability and well-being when worn depend on it heavily on the nature of the brandoohleninaterialo used away. The materials used for this should therefore be light and flexible, have sufficient strength and the mechanical Beano training during shoe production and when wearing the Shoes to be able to cope with. They should be sufficiently permeable to air and water vapor, and humidity should be reversible can absorb and release and be resistant to sweat, bacterial and pila action.

For this purpose, light and flexible types of leather, especially split leather with a relatively open, but firm and tough structure is used.

These traditional insole leathers are increasingly being processed with insoles that have been manufactured using plastics. So are z. B. made of leather fibers for this purpose simply by using certain synthetic resin dispersions as binders, much more flexible materials than previously known based on leather fibers.

Also known are leather substitutes for insoles based on fabrics, fleeces or so-called scrims made of synthetic and / or natural fibers, which according to known methods with the help of natural or synthetic, preferably elaetoraeren, polymers or also by i. ^r era-

and pressure application initeinandor connected b / .w. are misled. These leather substitutes are known in shoe manufacturing, z. B. alö so-called cap fibers for the stiffening of the tip and / or Persen parts of shoes or in Sohuhuntorbau.

Also known are kunot leather-like fabrics on the Baois von Woven or knitted, on the one hand, a usual spread made of plastic on the basis of polyvinyl chloride on the other hand an adhesive line for sticking the artificial leather on impermeable Own documents.

Also known are Deokbranclsphlen made of leather with eln & r ^ Self-adhesive layer on the back for easier replacement voi. worn or damaged Peckbrar soles.

The known insole materials are identical in their application and require a multitude of work steps for the yerarbeli'un ^ to ochuh: First the insole is punched out and attached to the last by stapling. The hands of the insole are then roughened and coated with an adhesive that allows longer or shorter periods of time to flash off. The prefabricated upper is then pulled over the last and overtaken with the help of a lasting machine, possibly with the use of Eincher cements, and attached to the insole. Subsequently, the unevenness of the substructure is leveled out with Au / l ballt ¹ aas en, in which case it may be necessary to use glue again to fix it to the insole and then fix the lower cavity by gluing, sewing or nailing. In the shoe bucket, the actual, mostly unsightly and rough insole is pasted over with a top fire sole. The last-mentioned operation is usually necessary, although it makes it more expensive and also gives rise to some errors and malfunctions in production. When gluing on the largely finished shoe, which can usually only be done by hand, the upper leather is easily soiled. It is difficult to properly import the thin, very flexible insole into the shoe and therefore only stiffer materials that have a certain stability can be processed safely and cleanly. Very often those that have been glued in later also loosen

Synthetic or synthetic rubber, polyesters, acrylonitrile-butadiene-styrene copolyraerisates and the like on the carrier layer Can be applied in the usual way, with the aid of pressure, heat and / or lamination aids: The coating layer of the insole material according to the invention can also consist of an artificial leather, in particular an artificial leather with a light, pliable, textile base, for example an open, light fabric. This artificial leather of light quality, the plastic content of which is preferably made from soft moss Vinyl chloride polymers is made in the same way ./eise, wie the above-mentioned plastic film laminated onto the carrier layer. When using, for example, the very adjusted plastisols of vinyl chloride polymers as a lamination aid for very thin plastic films or very light ones Kuiiut leather qualities are particularly elastic and when worn Get pleasant-looking overlay stories. The same or A similar effect can of course be achieved if - as described above - instead of the foil or the artificial leather, the coating layer by applying plastic dispersions or plastleolen.

Particularly valuable effects can be achieved with a thin foam intermediate layer between the carrier layer and the cover layer. The use of laminating adhesives, which also act as welding aids, then allows foot-friendly, cushion-like embossing to be applied to the insole through high-frequency welding, or permanent deformations adapted to the foot.

The adhesive line on the bottom side of the insole material is made with adhesives known per se. Both self-adhesive coatings and adhesive solutions can be used or dispersions are applied and, preferably, those caused by solvents and / or heat and optionally Adhesive lines that can be activated by pressure result. Such adhesive layers can also be used as an adhesive film on the load-bearing layer of the Composite material, e.g. B. by the action of heat and pressure, are concealed.
