ABSTRACT:
The present disclosure illustrates a hub assembly for holding core segments which segments as held by the hub assembly are utilized in the centrifugal casting of vehicle tires. The core segments are held in circumferentially extending relationship to each other to form an annularly extending core. The hub assembly is comprised of a hub member and a hub ring that can be quickly and conveniently connected together to hold the core segments and in a like manner can be disassembled to release the core segments so the core segments can be disassembled from their circumferentially extending relationship to each other and removed from a finished tire. The present disclosure also includes an apparatus for automatically, as distinguished from manually, separating and removing the two parts of the hub assembly from the central opening of a centrifugally cast vehicle tire.
