A process for forming such manufactured items as imitation leather, or the like, from thermoplastic materials, thermosetting materials or elastomers, having at least one foamed layer, characterized in that said process comprises the following steps: a) forming, inside a mold for slush molding, a first layer of material which will constitute the top (i.e., the visible) layer of the finished manufactured item, b) by means of a further slush molding step forming a second layer, of foaming material, on said first layer, c) under high temperature conditions, completing the consolidation by gelation of said layers and foaming said second layer, by suitable means, in order to obtain predetermined thicknesses and shapes of said foamed layer, with the so formed layered material a backing means made from a rigid material being coupled, wherein said suitable means for obtaining predetermined thicknesses and shapes of said foamed layer are constituted either by a counter-mold or by said backing means made of rigid material.

[ We claim:] [1.] Process for forming manufactured items from thermoplastic materials, thermosetting materials or elastomers, having at least one foamed layer, said process comprises the following steps:forming, inside a mould for slush moulding, a first layer of material which constitutes the top layer of the finished manufactured item,charging to said mould said backing means made of rigid material,by means of a further slush moulding step forming a second layer, of foaming material, on said first layer, in such a way said second layer substantially embedding said backing means of rigid material,under high temperature conditions, completing the consolidation by gelation of said layers and foaming said second layer, by suitable means, in order to obtain predetermined thicknesses and shapes of said second layer,coupling said second layer to a backing means made of a rigid material,wherein said suitable means for obtaining predetermined thicknesses and shapes of said second layer are constituted either by a counter-mould or by said backing means made of rigid material, andcooling said mould and de-moulding the thus finished manufactured article containing said rigid backing means embedded therein.
