ABSTRACT:
A vulcanization mold for producing laminated bodies, particularly shoe soles of different and/or differently colored rubbers or plastics, the interfacial boundary between adjacent plies of the laminate forming non-planar surfaces, is provided. The mold includes several mold cavities, disposed one on top of the other for forming the individual layers of the laminate, the mold cavities being separated by intermediate plates which are removable from the mold following a prevulcanization to allow for uniting of the premolded individual layers into the desired laminated body. A middle plate freely moveable in the direction of opening and closing of the mold together with two intermediate plates disposed on opposite sides thereof form the mold cavity for a central layer of the laminate, the surfaces of the middle plate being non-planar and corresponding to the adjacent surfaces of the intermediate plates. The laminated bodies are produced by inserting blanks into the mold cavities, shaping and prevulcanizing the blanks, opening the mold and removing the intermediate plates and closing the mold and fully curing the pre-vulcanized layers into the finished composite.
