ABSTRACT:
A tire former for use in a tire building apparatus, the tire former includes a center ring provided coaxially around a drum shaft and a pair of side rings provided coaxially around the drum shaft and on opposite sides of the center ring. The center ring consists of a plurality of circumferentially separatable ring segments. The side rings are movable closer to and away from each other along the shaft to selectively provide an axially expanded state where the side rings are positioned on opposite sides of the center ring and an outer circumferential surface of the side rings is flush with an outer circumferential of the center ring; and an axially contracted state where the side rings are positioned radially inside of the center ring.
