Abstract
The belt-shaped member supplying method and apparatus are used for cutting a long material paid out of a winding roll into a belt-shaped member of a predetermined length and supplying the belt-shaped member onto a winding drum by means of a transfer device. The method includes steps of modifying an extending direction of a front edge of a long material, whose initial front end portion has been cut off, into a desired direction by applying an external force upon a front end portion of the long material, holding the front end portion of the long material, paying out the long material of a predetermined length, cutting the paid long material to form a belt-shaped member, modifying an extending direction of a rear edge of the belt-shaped member into a desired direction by applying an external force upon a rear end portion of the belt-shaped member, holding the rear end portion of the belt-shaped member, transferring the entire belt-shaped member to a predetermined position, taking up any slack of the belt-shaped member, holding the belt-shaped member against a plate-shaped transfer device, and moving the plate-shaped transfer device together with the belt-shaped member to the winding d…
