Abstract

Prodn. of pregelled shoe soles in the hollow space of a mould is effected by (a) continuously displacing the mould to supply synthetic powder e.g. a silicone rubber, into the mould cavity, and spread it out in a smooth manner, (b) pregelling this powder, and (c) withdrawing the mould into its initial position. Process gives efficient formation of smooth layers of thermoplastic powder in the mould cavity.
