A plurality of mold assemblies including an upper mold and a lower mold movable axially toward one another are removably mounted on the machine with each lower mold on the periphery of the hub. Mounting construction is interposed between the lower mold and the hub. Each mounting arrangement has an arcuate surface engaging a portion of the periphery of the cylindrical hub such that the lower mold can be removed and replaced on the hub by different size molds.
