Abstract

Mfr. of a shoe sole composed of 2 injection-mouldable e.g. polyurethane, parts comprises moulding a 1st sole section in a 1st moulding station, moving it along a pre-determined path along in such a way that it returns to the 1st station after a time sufficient to allow it to set at least partly; and then at once moulding a 2nd sole section or sole ply onto the 1st sole section, and simultaneously moulding a fresh, separate 1st sole section; all these operations being effected at the 1st moulding station.
