ABSTRACT:
A moulding apparatus and a method of moulding for components of unvulcanized elastomeric material which forms a spew free component and provides for handling the component for subsequent use. The apparatus as shown in the Figures comprises a first mould member having a mould cavity for part of the component and a feed port for material and a second complementary mould member which includes a detachable component carrying insert. The two mould members and are relatively movable to provide two different volumes for the mould cavity, the change to the smaller volume being used to return some material through the feed port and to complete moulding of the component.
