ABSTRACT:
This disclosure relates to a retread mold defined by a pair of relatively movable platens, means for imparting relative motion to the platens between spaced open and closed positions thereof, a matrix carried by each platen, biasing means between each platen and its associated matrix for biasingly urging the matrices and platens to a position of spaced relationship from each other in the open position of the platens, and the spaced relationship being reducible in opposition to the force of the biasing means upon movement of the platens to the closed position thereof.
