Abstract
The quality and useful life of curing bladders used in standard 'Bag-O-Matic' tire vulcanizing presses is greatly improved by replacing the standard split two-piece core of the bladder mold with a unitary core which forms a disc-like rubber diaphragm below the core and integral with the rubber curing bladder at the periphery of the core. A unique base plate fits in the lower mold half below the core and has a grooved upper surface to hold the diaphragm in place so that the core can be removed manually or automatically with the assistance of internal air pressure.
