METHOD FOR MANUFACTURING SHOES

PURPOSE: To simplify the work, shorten the manufacturing time, and reduce the manufacturing cost by a method wherein a shoe sole and and an internal sole are integrally formed by an injection method or a vulcanized method, and a molten resin is prevented from leaking out from a non-connected part which is located at the opening of a vamp and quater part. CONSTITUTION: On an internal bottom 3, a pair of fan-shaped protruding parts 3, which protrude to the outside of the lower peripheral edge (1a) of a last 1, are formed, and the internal sole 3 and a vamp and quater part 2 are fixed by sewing process excepting an opening 10, and are connected, and a bag-form body 4 is formed. Then, the last 1 is fitted in the bag-form body 4, and the bag-form body 4 together with the last 1, is mounted on a sole mold 5 with the internal sole 3 facing down. Between the upper peripheral edge 5b of a recessed part 5a of the sole mold 5, and the lower peripheral edge (1a) of the last 1, the protruding parts 3a of the internal sole 3 are pinched with the leading ends being bent upward. Then, a molten shoe sole forming material, e.g., a vinyl chloride resin, polyurethane, or a thermoplastic rubber, etc., is inject- charged from an injection nozzle through a gate 5c into a shoe sole forming gap 6, and a shoe sole 7 and the internal sole 3 are integrally formed.
