Abstract

Liquid heating medium at high pressure is introduced into the bladder to force and maintain the tyre being cured against the surface of the enclosing mould, the medium being at the maximum curing temperature of the tyre. In the final phase of the heating period a gas or vapour at high pressure, and at about the same temperature as the liquid medium, is introduced into the bladder to force the liquid medium from the bladder without interrupting the cure. The end of the liquid emptying operation preferably coincides with the completion of cure. Provides shortening of the cycle time in tyre press operation.
