Abstract

105,426. East, F. W., and East, A. G. April 26, 1916. Extrusion machines. -In a screw extrusion press for making rubber goods, for example solid tyres, in continuous lengths, the mould A comprises a cylindrical casing hollowed at G and formed with die passages D, which are disposed opposite to the threaded portion C' of the screw C. The mould is recessed at A' to receive the end C<3> of the screw, and the thread C<2> terminates short of the mould to provide space E for the material, which may be formed as an annular recess in the mould into which the die passages open. For hollow articles, the ends of the dies are tapered and are fitted with conical wing-plugs H carrying covers H<l>. Steam for heating the mould is circulated through a jacket F and also, or alternatively, through the hollow G.
