Abstract

Mould carrier for supporting moulds for the prodn. of articles from polyurethane or a similar foamable plastic material consists of a feed pipe capable of being blocked by a blocking organ operated by a fluid under pressure. Used for the prodn. of foamed polyurethane articles, such as shoe soles. The mould carrier prevents the leakage of the polyurethane introduced into the mould, at the moment of its expansion.
