TIRE TREAD FORMING METHOD AND APPARATUS Abstract of the Disclosure A body having rubber material thereon is positioned on a lower member, and an upper member is moved toward the lower member, such relative movement causing tread-forming shoes to move to inward positions to form a tread on the rubber material. As an alternative, the upper and lower members may be brought together, and rubber material may be injected into position to have a tread formed thereon. Upon movement of the upper and lower member relatively apart, the rubber material is made to remain in contact with the shoes, and the body is removed, whereupon an annular core having rubber material thereon is disposed on the lower member, and the upper and lower members are again brought together to deposit the rubber material in contact with the shoes onto the rubber material on the core.
