Abstract

A belt-shaped member cut into a predetermined length is fed from a feeding devices to a tire forming drum and is wound on its cylindrical peripheral surface. Center portions of the opposite ends of the belt-shaped member are pushed to be joined to each other and the side portions of at least one of the opposite ends of the belt-shaped member are held by upper and lower holding pawls. Such holding pawls are swung along an arcuate path so that both side portions of the opposite ends of the belt-shaped member are drawn near each other to abut against each other. The abutting end portions are pushed toward the peripheral surface of the drum by pushing devices for joining them together.
