Abstract
Improvements in the invention patent no. 378,027 by "improvement in the molding of pieces of upholstered plastic foam", in which, prior to the introduction of the expandable plastic material inside the mold, it is applied to the molding walls thereof and adapting it perfectly with formation under vacuum, a sheet with a decorative finish on its face, preferably two-dimensionally elastic, for which purpose it is constituted by a knitted support covered with a layer of thermoplastic material that is partially inserted into said fabric of gender knitted, whose threads remain adhered by one of the faces of the sheet to the thermoplastic material and the other protrude from it, or is constituted by a plastic sheet with a surface view of decorative effect and internal surface suitable for anchoring with foam of polyurethane, followed immediately by the molding operation itself, by introduction of the expandable and closed material of the mold, while the sheet continues to be subjected to the action of the vacuum so that it remains perfectly adhered to the walls of the mold, maintaining the vacuum until the expanded material reaches its dimensional stability and does not deform any more, in which the vacuum ceases and the piece is removed from the mold, thus obtaining a piece that must have sufficient elasticity to remain adhered to the molded foam, following all possible shape changes to which its elasticity and function may be subject piece in question, characterized by the fact that the elastic sheet starting, preferably in pvc, optionally coupled to a layer of "foam", is subject to an initial conformation in the mold itself, by a vacuum action with eventual contribution of heat, the injection of the expandable plastic material of flexible or semi-rigid type then taking place subsequently on the above material a rigid laminar piece, so that the resulting assembly is a substantially laminar composite body in which the front face is the one corresponding to the elastic sheet, while the rear face is the rigid sheet in support functions applicable to a surface or structure to be coated.
