Abstract

Spring-loaded rollers for a mold have an axle mount which passes through the roller into a supporting portion of the seats in the platen to prevent the roller from rotating, twisting or otherwise moving in the set, thereby reducing wear in the roller assemby and in the mold. The roller assembly is easily removed from its seat through the use of a removal device cooperating with screw threads in the roller. A plurality of rollers are used to permit a mold to be easily moved into and out of position in a press. The mold is thus mounted in position since the rollers limit the ability of the mold to move laterally.
