Method for retreading tires
Abstract
Abstract A method for manipulating and curing a tire having at least the tread renewed including the tire in mold sections having an internal diameter in the tread area substantially the same as the external diameter of the tread portion of the tire by engaging the beads of the tire with bead ring portions of the extended bladder assemblies to center the tire between the mold sections, inflating the tire to partially retract the bead rings thereby displacing the beads of the tire outwardly to reduce the external diameter of the tread portion of the tire, encapsulating the tire within the mold by extending the mold sections to the closed position while maintaining the beads of the tire displaced outwardly, and bringing the bolsters into contact with the mold sections to return the beads of the tire to their original position before curing.
