Abstract
Improvements in the manufacture of polychrome and embossed rubber sheet pieces, essentially characterized by the fact of separately mixing two rubber masses with the corresponding dyes, one of whose masses is intended to be used as a laminar support of substantially uniform thickness, while the other mass will constitute the raised elements that will be arranged on one of the faces of the piece, followed by the molding at approximately 160 to 200º C of this second mass, whose resulting elements are subsequently removed from the mold to proceed with the elimination of remains and achieve their perfect finish, these elements being finally arranged again in the corresponding mold and then being filled with the constituent mass of the laminar support, carrying out a second joint molding operation at approximately 160 to 200º C, after which the piece is removed from the mold and to finished forming a whole, which undergoes a final polishing operation.
