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.

1 . A semimanufactured waterproofed product ( 1 ), particularly shoes, clothing items and accessories, having a three-dimensional conformation, at least one inner surface ( 2 ) and one outer surface, the product comprising at least a pair of sheets ( 5 ) of a semi-permeable membrane pressed onto the inner surface ( 2 ) temporarily turned inside out, wherein the surface of the sheets ( 5 ) which is turned toward the semimanufactured product ( 1 ) is provided with a glue pattern. 
     
     
         2 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein the semi-permeable membranes ( 5 ) extend beyond a profile of the semimanufactured product ( 1 ) temporarily turned inside out, so that they adhere to each other and form one or two strips ( 7 ) that seal the semimanufactured product ( 1 ). 
     
     
         3 . The semimanufactured waterproofed product ( 1 ) according to  claim 2 , wherein the strips ( 7 ) are arranged along folding lines ( 3 ) of the semimanufactured waterproofed product ( 1 ) which is folded and flattened when the semi-permeable membranes ( 5 ) are pressed onto the semimanufactured product ( 1 ). 
     
     
         4 . The semimanufactured waterproofed product ( 1 ) according to  claim 3 , wherein the folding lines ( 3 ) correspond to the intersection of the semimanufactured product ( 1 ) with a symmetry plane thereof, so as to obtain two opposing surfaces, which are substantially the same. 
     
     
         5 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein the glue pattern of the semi-permeable membranes ( 5 ) is thermoadhesive. 
     
     
         6 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein the glue pattern comprises a multiplicity of dots having a diameter between 0.1 mm and 0.8 mm. 
     
     
         7 . The semimanufactured waterproofed product ( 1 ) according to  claim 6 , wherein the glue pattern comprises a multiplicity of dots having a density between 50 dots/cm 2  and 200 dots/cm 2 . 
     
     
         8 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein at least one semi-permeable membrane ( 5 ) is not porous and carries out water vapor passage by osmosis. 
     
     
         9 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein at least one semi-permeable membrane ( 5 ) is elastic with a grade of elongation higher than 50%. 
     
     
         10 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein at least one semi-permeable membrane ( 5 ) comprises polyurethane. 
     
     
         11 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein at least one semi-permeable membrane ( 5 ) has a thickness between 5 μm and 100 μm. 
     
     
         12 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , wherein at least one semi-permeable membrane ( 5 ) is combined with a support sheet. 
     
     
         13 . The semimanufactured waterproofed product ( 1 ) according to  claim 12 , wherein the support sheet comprises fabric or a similar material, which is firmly fastened to the membrane ( 5 ). 
     
     
         14 . The semimanufactured waterproofed product ( 1 ) according to  claim 1 , which comprises a shoe upper.
