Process and machine for water proofing semimanufactured footwear, clothing items and accessories, and semimanufactured products obtained with said process or machine

摘要

Embodiments provide a process and machine for waterproofing semimanufactured footwear, clothing items, and accessories. Embodiments also provide semimanufactured products obtained with said process and/or machine. The semimanufactured product may have a three-dimensional conformation with an inner surface and an outer surface. A waterproofing sheath may be formed by superimposing two edges of a semi-permeable membrane, and welding the superimposed edges of the semi-permeable membrane to one another to form a strip and to give the waterproofing sheath a three-dimensional conformation. The semimanufactured product and three-dimensional waterproofing sheath may be arranged on a shaped support with an adhesive between the semimanufactured product and the waterproofing sheath. The semimanufactured product and/or waterproofing sheath may be pressed to bond the waterproofing sheath to the surface of the semimanufactured product.

主权项

1. A process for waterproofing a semimanufactured product having a three dimensional conformation with an inner surface and an outer surface, the process comprising:
preparing a waterproofing sheath, the preparing including:
superimposing two edges of a membrane; andwelding the superimposed edges of the membrane to one another to give the waterproofing sheath a three-dimensional conformation; arranging the semimanufactured product onto a shaped support with the waterproofing sheath covering a surface of the semimanufactured product that is to be waterproofed, wherein the shaped support is oriented substantially vertically; and pressing the semimanufactured product, after the arranging of the semimanufactured product onto the shaped support, to bond the waterproofing sheath to the surface of the semimanufactured product; wherein the pressing includes pressing the semimanufactured product between two deformable plates by rotating at least one of the deformable plates around a substantially vertical axis.
