Abstract

In a cylindrical tire forming member building method or apparatus, after the front end portion of a belt-shaped material is pressed against the drum, the belt-shaped material is wound on the drum while being centered, and with the central portion of the rear end portion of the belt-shaped material pressed against the drum with a robot hand, both edge portions of the rear end portion of the belt-shaped material are elongated longitudinally and pressed against the drum with the robot hand, so that the front and rear ends of the belt-shaped material are butt-joined without forming a gap therebetween or without being overlapped.
