Abstract
Improvements in the processes for the upholstery of molded parts in synthetic expanded material, during the process of molding them, specifically in the upholstery procedures according to which a layer of flexible, elastic and omnidirectionally extensible coating is placed in flat form and is fixed peripherally, with the possibility of controlled sliding, on the foaming mold (at room temperature or with the help of heat to increase the elasticity of the coating layer without exceeding the elastic limit thereof), and, by means of vacuum, the coating layer is exactly adapted to the walls of the mold, whereby the coating thus formed is not permanently shaped, being formed only after filling with expanded material, thanks to the combined action of heat and the pressure of the expanded material that help to confer a permanent shape to the finished piece and the adhesion of the material and the coating is permanently maintained in this form, characterized in that the coating layer, resistant to abrasion and provided with springs and waterproof characteristics, is anchored to the molded part in expanded material by means of an anchoring layer, endowed with springs and spring characteristics. Spongy composition of open pore, whose stratum is joined on one side to the coating layer and on the other side is joined, at the time of molding the piece, to the corresponding surface of the said molded piece, by adhesion and impregnation with the expanded material, constitutive of said piece, which penetrates and solidifies inside the pores of the anchoring layer, in an area of variable depth depending on the viscosity of the expanded material, the size of the pores of the stratum anchoring and pressure and molding temperature.
