Also, a driving action of a rotation-drive source, which controls the movement of the movable guide roller support arms, is synchronized with the braking of the film supply role and the movement of the leading edge of the film towards the bonding surface. This device prevents longitudinal wrinkles in the film, misplacement on the bonding surface, and excessive tension on the film.
