ABSTRACT:
A curing ring device for a precured tread rubber recapping apparatus of the type wherein a tire assembly with a strip of tread rubber in place on a tire carcass is surrounded by a flexible envelope. The curing ring device which seals the envelope around the tire in its bead area comprises an annular pressure ring that engages the envelope around the tire bead area and has a plurality of backup pads that engage the inside of the tire bead at spaced apart locations. A single handle controls a linkage system that interconnects the pressure ring and the backup pads and closes them together so that sealing pressure is supplied by the ring against the envelope. The linkage system includes elements enabling the distance between the pressure ring and the backup pads in their closed, clamping position to be adjusted so that tires with different bead thicknesses can be accommodated by the device.
