Abstract
A method of attaching a belt-like member being transferred by a conveyor to a circumference of a drum comprises steps of detecting a leading end and a trailing end of the belt-like member, respectively, transferring the belt-like member by the conveyor until the leading end of the member arrives at a leading end set position, and further transferring the belt-like member and rotating the drum to attach the belt-like member to the circumference of the drum so that at the same time when the leading end of the belt-like member attached to the drum arrives at a set rotated position, the trailing end of the belt-like member arrives at a trailing end set position spaced a predetermined distance from a trailing end detected position where the tailing end was detected in the first step, thereby jointing the leading and trailing ends. In this manner, the belt-like member is attached uniformly on the drum to compensate any excess and shortage in length of the belt-like member relative to a circumferential length of the drum. If the belt-like member has leading and trailing ends bias to longitudinal directions of the member, the belt-like member is transferred at a speed substantially equal to a circumferential speed of the drum only during attaching the bias leading and trailing ends to the drum to avoid deformations of the leading and trailing ends.
