Abstract

A method of setting a crude tire into a space between upper and lower molds in a tire vulcanizing press having upper and lower mold units movable relative to each other includes the steps of pushing an upper bead of the crude tire into a bead of the upper mold by a vertically movable device which supports the upper bead of the crude tire, introducing gas into a bladder to expand the bladder while restricting the elevation of an upper portion fixing ring of a bladder holder mechanism attached to the lower mold unit, and pushing a lower bead of the crude tire into a bead of the lower mold by utilizing the expansion forces of the bladder. With the bladder enclosed air-tightly, the tire lower bead can efficiently be pushed into the lower mold bead.
