ABSTRACT:
A method for forming soft, resilient, smooth, energy dissipating articles from foamed partially cross-linked polyolefins wherein sheet stock is cut into a preform and the preform while at room temperature is positioned within a mold cavity formed by partible mold halves. The preforms and the cavity of the molds are so arranged and constructed that after molding there is no flashing needing trimming because the polyolefin is substantially confined within the cavity without any lateral projection into the parting surfaces of the mold.
