ABSTRACT:
A process using a mold having at least two complementary parts provided with internal surfaces defining a molding cavity, including placing a cover element on the internal surface of each mold part, extending the periphery of the cover elements beyond that of the internal surfaces, pouring a foaming composition undergoing reaction onto the cover element of one of the mold parts, waiting until the foam further expands and overflows slightly from the part of the mold into which it was poured, applying the other mold part to the first one so as to close the molding cavity, pressing the overflow foam into the extended cover elements, waiting until the foam fully cures, removing the padding from the mold and trimming the cover elements along the line joining them.
