Abstract

Improvements in the molding of pieces in upholstered plastic foam, characterized in that prior to the introduction of the expandable plastic material inside the mold, it is applied to the molding walls of the mold and adapts it perfectly with formation under vacuum, at room temperature, a sheet, with a decorative finish on its exposed side, two-dimensionally elastic, for which purpose it is optionally constituted by a knitted support covered with a layer of thermoplastic material that is partially inserted into said knitted fabric, the threads of which are Adhered by one side of the sheet to the thermoplastic material and protruding from the other side, or it is made up of a plastic sheet with visible surface for decorative effect and internal surface suitably treated with mechanical, physical or chemical means, to confer characteristics anchor to the polyurethane foam, or is made up of a n elastic fabric waterproofed and treated to anchor the foam, then proceeding to the actual molding operation, by introducing the expandable and closed material of the mold, while the sheet continues to be subjected to the action of 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 is no longer deformed, at which time the vacuum ceases, and the piece is removed from the mold, thus obtaining a piece of molded expanded material adhered to the sheet, which must have sufficient elasticity to remain adhered to the molded foam, following all possible changes so that due to its elasticity and function the piece in question may be subjected.
