Abstract
It consists in carrying out the following operations: a) on a machine for injecting plastics, an operation of moulding two independent pieces or blocks, one of which corresponds to the front part (toe and instep of a shoe and corresponding part of the base (sole)), and the other to the rear part (heel and base for the shoe heel) b) a refining operation for the outer finishing of the two independent blocks obtained in the injection-moulding operation. During the moulding operation, each piece has an external enlargement which is removed during the refining operation, in the same way as are produced the grooves and couplings between pieces and for the arrangement and assembly of the articulation means. Also in the moulding operation, the cavities which determine a regular thickness of the walls of the block are obtained.
