Embodiment Construction

[0014] As can be seen in the preceding figures, the process of "valgus stitching" for shoemaking is that the edges of the upper (1) are set / turned outwards and are sewn to the corresponding Sole (3) or welt, such as figure 1 shown.

[0015] In this respect, the novelty consists in the protection of the seam (2) by means of a strip of raw rubber (4) which is then vulcanized together with the rest of the shoe in a vulcanization tank, thus providing in this way not only the seam of the shoe (2) Further protection and waterproofing of the shoe, and an enhanced bond between the upper (1) and the sole or welt (3), which not only resists water but also external actions such as friction.

[0016] The shoe corresponding to the invention and with the above-mentioned improvements does not require an insole and, moreover, since the fixation of the upper to the sole is achieved by seams instead of gluing, the use of adhesives is reduced, resulting in a very flexible shoe.

Abstract

The invention relates to a system for protecting a seam (2) produced by the "stitch down" process, by means of sealing with a rubber strip, said seam being produced by stitching the outwardly mounted edge of the corresponding upper (1) to the corresponding sole (3) or welt, in such a way that the rubber strip (4) is fixed by vulcanisation, sealing the seam (2) itself, and thereby waterproofing the seam and the shoe.

Description

technical field [0001] The present invention relates to a system for protecting the seam of a shoe upper, wherein said seam is secured by sewing the outwardly protruding edge of the upper to the sole or welt of the shoe itself, a process called "valgus". stitch". [0002] The object of the present invention is to achieve the waterproofing of the above-mentioned seams, and thus of the seams made of the aforementioned "eversion-stitching" system. Background technique [0003] There are a few processes used in the manufacture of shoes, and the most well-known that can be mentioned are "Lapping (Storbel)" and "Valsion Stitching", for the former the upper is formed by stitching the insole to the upper in a zigzag pattern For the latter, the insole is fixed to the sole, and the upper is then fastened and bonded to the sole, so that the fastening seam of the insole is exposed from the shoe, and it therefore lacks water resistance in general. [0004] This problem is trying to be ...
