摘要

Process for waterproofing a semimanufactured product (3) of footwear, gloves, clothing items and accessories, said semimanufactured product (3) having a three-dimensional conformation with at least one inner surface and one outer surface, characterized in that it comprises the following operative steps:
arranging on a shaped support (1, 1a, 1b) the semimanufactured product (3) with at least one waterproofing sheath (4) shaped for entirely or partially cover the surfaces to be waterproofed of the semimanufactured product (3), at least one glue layer being applied between these surfaces and the waterproofing sheath (4);sealing the semimanufactured product (3) and/or the waterproofing sheath (4) for preventing the transfer of fluids from the outside between the sheath (4) and the shaped support (1, 1a, 1b);inserting the shaped support (1, 1a, 1b) provided with the semimanufactured product (3) and with the sheath (4) into an autoclave (7) for joining under pressure the sheath (4) to the semimanufactured product (3).;The present invention also relates to a system that carries out said process, as well as the products obtained with said process or system.

主权项

1. A method for waterproofing a semimanufactured product of footwear, gloves, clothing items, or accessories, said semimanufactured product having a three-dimensional conformation with at least one inner surface and one outer surface, the method comprising:
arranging on a shaped support the semimanufactured product with at least one waterproofing sheath shaped to entirely or partially cover one or more surfaces of the semimanufactured product to be waterproofed, wherein glue is applied between the surfaces to be waterproofed and the waterproofing sheath, wherein the waterproofing sheath is a three-dimensional membrane that is breathable, elastomeric and is made of a single piece; sealing an opening between the semimanufactured product and the waterproofing sheath to prevent entry of fluid between the sheath and the shaped support through the opening; and inserting the shaped support provided with the semimanufactured product and with the sheath into an autoclave for joining, under pressure and/or heat, the sheath to the semimanufactured product; wherein the sealing is performed prior to the sheath being joined to the semimanufactured product in the autoclave.
