Method and apparatus for molding polyurethane soles for footwear

摘要

Two component polyurethane soles for footwear are molded continuously in an apparatus including a turntable with a plurality of mold stations therearound. While a first sole portion is being molded at one mold station, a second sole portion interconnecting the first sole portion to a lasted upper is molded at the same mold station. Such simultaneous molding is achieved using a mold bottom or top which retains the first sole portion and with such first sole portion forms part of the mold for forming the second sole portion. The second sole portion mold is completed by mold sides and a lasted upper.
