ABSTRACT:
A bladder leak and rupture detector employs a low level flow sensor for detecting both bladder leaks and ruptures. False failure signals are avoided by a dual mode logic circuit which monitors for bladder leaks or low level failures only during a preselected portion of the curing cycle and at other times requires sustained flow through the sensor for a predetermined time to indicate bladder ruptures or high level failures. In either case, a warning signal is generated and the cycle may be interrupted to prevent loadng of a next tire into the curing press. Leakage flow passages may be provided for both upper and lower portions of the tire mold cavity to ensure detection of leaks, and vent passages with shut-off valves are provided to facilitate low level leak detection.
