Abstract
A die member forming a component of cross-head die apparatus is configured to facilitate removal of the die member from the axial bore of the body of the apparatus following assembly of a die member at room temperature with a body at elevated temperature. The external, frustoconical surface of prior art die members is provided with recessed portions which do not contact the opposing surface of the axial bore in the body. Also, the angle of taper of the conical plane of the mating die member and body bore surfaces is increased to 7.degree. from the prior art standard of 5.degree..
