Semimanufactured Waterproofed Products, Particularly Shoes, Clothing Items and Accessories

Abstract

Semimanufactured waterproofed products (1), particularly shoes, clothing items and accessories, are provided having a three-dimensional conformation with at least one inner surface (2) and one outer surface, provided by the following operative steps:turning inside out the semimanufactured product (1) so that its inner surface (2) is turned outwards;inserting at least one shaped member (4; 8) inside the semimanufactured product (1);pressing the semimanufactured product (1) provided with the shaped member (4; 8) between at least a pair of sheets (5) of a semi-permeable membrane whose surface turned toward the semimanufactured product (1) turned inside out is provided with a glue pattern; andturning the semimanufactured product (1) so that its inner surface is turned inwards.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 10 / 358,465, filed Feb. 5, 2003, which was a continuation of International Patent Application No. PCT / IT01 / 00424, filed Jul. 31, 2001, published in the English language on Feb. 14, 2002, under International Publication No. WO 02 / 11571, and the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a process for waterproofing semimanufactured shoes, clothing items and accessories, in particular during their manufacture. The present invention also relates to a device for carrying out the process and the semimanufactured products obtained with the process.[0003]The International application publication No. WO 00 / 22948 in the name of SAES Getters S.p.A. discloses a process for waterproofing leather and semimanufactured products made up of leather pieces sewed together. This known process comprises a pressing...

AI Technical Summary

Benefits of technology

[0010]Thanks to the turning inside out and to the shaped member which is inserted before the pressing into the semimanufactured product, it is possible to waterproof the latter also if it is already provided with a three-dimensional conformation. With this arrangement, the semi-permeable membranes, when pressed, can perfectly adhere to the surfaces of the semimanufactured product without any formation of pleats or wrinkles.

[0012]Another advantage of the process according to the present invention lies in the fact of being carried out in a simple and quick way without particularly complex and expensive machines, so that it can be employed not only in industrial production, but also in handicraft production, in particular of shoes.

Problems solved by technology

However, this known process cannot be applied to semimanufactured products made of leather or fabric, also joined with other materials, which cannot be completely stretched onto a table since they have already taken, during the manufacture, a three-dimensional conformation with at least one inner surface and one outer surface.

In this step it is not possible any more to stretch the shoe upper onto a table without overlapping portions of the shoe upper itself, with consequent permanent deterioration of the shoe upper, if pressed.
