Abstract
An apparatus and process for molding an outer sole of elastomer and an inner sole of a mixture of isocyanate and a polyol reacting into polyurethane to shoe uppers includes a vertically movable upper cross block supporting a pivotably mounted mold carrier with a heatable first mold part at one end for the molding of outer soles, and a lower, vertically adjustable cross block has a mold plate confronting the first mold part. The first mold part releases the molded outer sole on to the mold plate, the mold carrier is pivoted such that a cooled second mold part at the opposite end thereof overlies the molded outer sole which is then transferred to the second mold part, the mold carrier is again pivoted to confront the molded outer sole to a shoe last supported shoe upper, and an inner sole mold cavity is formed with the molded outer sole juxtaposed to the last supported shoe upper, and by an opposed pair of lateral mold elements closed about the shoe upper.
