ABSTRACT:
A tire-handling apparatus is provided for moving a tire into and out of a tire processor, such as a tire-curing press. The apparatus utilizes tire-gripping members, such as a plurality of shoes, which may be moved between an extended and a retracted position for gripping and releasing the tire respectively. Also included are operating members for properly operating the gripping members between their respective positions. The operating apparatus includes at least two cylinders having piston rods extending from first ends thereof. The second ends of the cylinders are mounted in series to permit the shoes for mounting the tire to be easily extended and retracted without substantial tire deformation, regardless of the size of the tire.
