ABSTRACT:
A loading process for a heated tire press is described herein in which a loader takes an unfinished tire from an unfinished tire stand and puts it between the tire forming pieces of the tire press. This loader travels with folded-in clamp jaws into the inside of the unfinished tire from below, engages it with extended clamp jaws inside of the upper bead from below, transports it in this position to the upper tire forming piece and raises it until its upper bead presses against the upper rim ring on the upper tire forming piece. The upper bead is held there by an auxiliary bellows, retaining fastener or the like. Subsequently the clamp jaws are folded in again and the loader retracted.
