Method and apparatus for attaching belt-shaped member to forming drum.

摘要

A method and an apparatus for attaching a belt-shaped member (15) to a forming drum (14). A belt-shaped member is transferred to the forming drum to pressure-join the front end of the belt-shaped member to the forming drum and the position of the rear end of the belt-shaped member is measured to obtain an excess or a shortage in length of the member. The rear end of the belt-shaped member is grasped by means of a grasping unit (68). Thereafter, the grasping unit is moved toward the forming drum (14), while the forming drum is rotating at a circumferential speed which is different from the moving speed of the grasping unit dependently upon the excess or the shortage of the member, thereby attaching the belt-shaped member to the forming drum and joining the front and rear ends of the member with each other. As an alternative, the grasping unit (68) is moved toward and away from the forming drum (14) dependently upon the excess or the shortage of the member (15) to make zero the excess or the shortage, while the grasping unit is moved at a speed of a constant ratio to the circumferential speed of the forming drum. <IMAGE>
