ABSTRACT:
To permit moulding of a rigid breaker tire in a single-phase diaphragm press without damage caused by axial movement of the tread-forming segments relative to the tire carcass in the mould the tread segments are mounted to pivot about fixed longitudinal axes as the press is opened and closed so that they move simultaneously both radially and axially with respect to the mould cavity.
