Abstract: 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.

Abstract: A machine for waterproofing semimanufactured products including footwear, clothing items, and accessories. The machine has a pressing device with at least one pair of deformable plates that have a hollow body. The pressing surface is elastic and suitable for being urged outwards by a fluid pressure. At least one of the deformable plates is fixed in a mobile manner to a support structure for opening or closing the pressing device around at least one shaped support which is provided with transport means to and from the pressing device and is suitable for supporting the semimanufactured product during the pressing with at least one waterproofing sheath.

Abstract: A semimanufactured product including footwear, clothing items and accessories, which has a three-dimensional conformation with at least one inner surface and one outer surface. At least one waterproofing sheath entirely or partially covers the inner surface of the semimanufactured product, adheres to the inner surface by means of at least one glue layer and includes at least one piece of semi-permeable membrane. The at least one piece of semi-permeable membrane is cut with a size of the inner surface of the semimanufactured product and is folded so as to superimpose two edges which are welded to form at least one strip and to give the waterproofing sheath a three-dimensional conformation similar to the semimanufactured product.

Abstract: Process for waterproofing semimanufactured footwear, clothing items and accessories, said semimanufactured product having a three-dimensional conformation with at least one inner surface and one outer surface, which comprises the following operative steps: arranging the semimanufactured product onto a shaped support (14; 27, 28; 30, 31) with at least one waterproofing sheath (18) shaped for entirely or partially cover the surfaces to be waterproofed of the semimanufactured product, at least one glue layer being arranged between these surfaces and the waterproofing sheath (18); pressing between two deformable plates (2, 2?) the semimanufactured product provided with the waterproofing sheath (18) and arranged on the shaped support (14; 27, 28; 30, 31). The present invention also relates to a machine that carries out said process, as well as the semimanufactured products obtained with said process or machine.

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; and turning the semimanufactured product (1) so that its inner surface is turned inwards.
