ABSTRACT:
A machine for the production of footwear by injection molding comprises a multiplicity of shoe molds on a common carrier, such as a turntable, moving successively past a core-insertion station and an injection station. At the insertion station, a mold core in the form of a last is lowered into an open shoe mold which then moves into alignment with an extruder at the injection station. The lowerable core support at the insertion station carries a feeler which, by coming to rest on an aligned mold or on the mold carrier, limits the descent of the core into the mold.
