Abstract

The invention concerns a procedure for the manufacture of vulcanised soles with a layer of expandable rubber and shoes with soles made in this way, in a process of vulcanisation with several stages with pre-vulcanisation of the base layer, in particular for the manufacture of separate soles, sports shoes, working boots and rubber shoes. In the manufacture of separate soles in expanded material, the procedure according to the invention consists in the fact that in the second stage of vulcanisation, in the same part of the mould in which the first stage occurred, an intermediate sole is formed with a non-vulcanised expandable rubber part. In order to produce a shoe with these soles, in the second vulcanisation stage, an intermediate sole in expandable rubber is attached to the base layer with simultaneous bonding of the upper part to the shoe (Figures 2 and 3). <IMAGE>
