Shoe upper and footwear constructed therewith and process for its production

Abstract

The footwear body has an upper material (13) with a lower end zone (19). A bonding strip (17) is around the bottom end of the footwear body. At the curved sections of the footwear, the bonding strip is bent around with a different curvature radius at the two sides to follow the footwear contour. The footwear body has an upper material (13) with a lower end zone (19). A lining gives a waterproofing function at the inner side of the upper material, with a lower lining section (21) which is not covered by the upper material at its bottom edge. A bonding strip (17) is around the bottom end of the footwear body, with one longitudinal side (23) bonded to the lower end zone of the upper material but not to the end zone of the lining, while the other longitudinal side is bonded to the end of the lining but not to the upper material. At the curved sections of the footwear, the bonding strip is bent around with a different curvature radius at the two sides to follow the footwear contour. The bonding strip can also be a stretch netting ribbon, impregnated with a sealant. The adhesive is a fusible adhesive, hydrocarbon or aliphatic hydrocarbon resin, or a condensation resin.

Description

field of invention [0001] The present invention relates to a shoe upper, a shoe made of the shoe upper and a method for making the shoe upper and the shoe. In order to obtain waterproof performance, the shoe upper contains a layer with a waterproof function and preferably a moisture-permeable function. In addition, the sole part must be sealed. Background of the invention [0002] An example of such a shoe is found in the applicant's patent EP 0 298 360 B1, in which the upper fabric is lined with an upper lining material comprising a waterproof functional layer. At the end near the sole, the upper fabric is cut shorter than the upper lining material so that the upper lining material protrudes a certain distance relative to the upper fabric. This protruding section is bridged by the mesh tape, and one longitudinal end of the mesh tape is sewn to the sole end of the upper lining material, while the other longitudinal end is sewn to the sole end of the upper lining material ins...

Problems solved by technology

[0005] In the shoe described in patent DE 195 03 405 C1, the inventors have tried to solve the problem of forming folds by connecting the lower end of the fabric to the insole by means of mesh straps, as in the usual shoes discussed earlier in this specification As is the case in the case, but the lining sheet containing the functional layer terminates at a distance from the insole like the fabric and is connected to the insole only through the outsole material, with the result that the lower end of the lining sheet can be removed before the outsole is molded. freedom of movement, which makes the production of shoes more difficult; moreover, this sole structure is only suitable for the manufacture of shoes with molded outsoles
