发明名称 METHOD AND APPARATUS FOR MANUFACTURING WATERPROOF FOOTWEAR WITH ATTACHED COMPRESSIBLE LINING
摘要 A method and apparatus for making a lined waterproof footwear product, and footwear product formed there from, are provided. A last, having an exterior surface configured to correspond to the size and shape of the interior surface of the footwear product, is covered with a microcellular lining material. An injection mold comprises shells having a pre-determined configuration to cooperate with the exterior surface of the lining covered last to form: (i) a pre-injection cavity between the shells and the lining covered last when in position in the mold for injection molding; and, (ii) an injection cavity, defining the configuration of the footwear product, between the shells and the lining covered last when injection material is being injected into the injection cavity whereby the injection pressure causes the microcellular lining material to reconfigure the pre-injection cavity.
