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 mould for slush moulding, 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 moulding 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-mould or by said backing means made of rigid material.

Procédé permettant de former des articles manufacturés tels que du cuir synthétique ou analogue, à partir de matériaux thermoplastiques, thermodurcissables ou élastomères, qui possèdent au moins une couche de mousse. Ledit procédé consiste (a) à former à l'intérieur d'un moule pour moulage par embouage une première couche d'un matériau qui constituera la couche supérieure (c'est-à-dire visible) de l'article manufacturé fini, (b) à former sur ladite première couche une seconde couche, constituée de mousse, grâce à une autre étape de moulage par embouage, (c) à effectuer, dans des conditions de température élevée, la consolidation par gélification desdites couches et le moussage de la seconde couche, par des moyens appropriés afin d'obtenir des épaisseurs et des formes prédéterminées de la couche de mousse, et à appliquer au matériau en couches ainsi obtenu un support constitué d'un matériau rigide, lesdits moyens appropriés pour obtenir les épaisseurs et formes prédéterminées de la couche de mousse étant constitués soit par un contre-moule, soit par ledit support en matériau rigide.
