Sole insert for shoes

The / innovation relates to a sole insert for shoes, in particular for slippers that. well oh / a special one; Terfahren not belonging to the furnace are produced ..- The. Eunststofftechnik has created the opportunity to. den- ¹ shoe ehafi / immediately one. Äandeinnahm- and the.Bolzfläche to be molded from plastic. There are two basic principles for this ^: .Mö "gii.Gfakeiten namely the use of a pastenförffilgeh; Kunstst _; openes,. That from the side under relatively little pressure. brought in, or the. Use of plasticized plastic granulate, which is injected under high pressure from the sole shell «V; .. - '■' ■ "■: --.-";-..-;; ^: - '■ "■' ■■ ■ '""" .- .-'

Another possibility is the felt insert laminated with a film.

For reasons of price, it can be expedient that the fiber-resistant protective layer is formed by a paper overlay in particular through a layer of crepe paper, which, due to its surface structure, goes particularly well with the sprayed-on Plastic sole connects and under the bending stresses that occur gives way easily, so does not break. It must be understandable be a paper that is not attacked by the high temperature of the injected plastic »

In other cases, a fabric cover, for example made of gauze, be appropriate, especially from the point of view of that a plastic can connect to the sole felt through the meshes of the fabric, ~ .-.

The finished sole consists of the outsole 1, the edging 2 and the sole insert 3, the sole insert 3 is by spraying on the running sole 1 - firmly connected to it.

According to the innovation, the sole insert 3 is made of felt.

The ice removal of lasers; To prevent the insole from being injected through the injection process ^{, the} insole should be provided with a fiber-resistant surface layer on the side facing the sole, as already said In this example, the above-mentioned covering with crepe paper is assumed, which, however, in accordance with the above explanations, is not the only option.
