<p>PURPOSE:To realize stable sticking in connecting films by providing a plurality of film unwinding mechanisms equipped with two chucking arms each having on one side a position control function in the width direction, and providing a copying function of these unwinding mechanisms as a whole for a belt-like body in the width direction. CONSTITUTION:Two film feeding reel shafts 3a, 3b are supported turnably around a reel turning shaft 2 as a center on a reel turning shaft fixing frame 14 which is displaced by a copying mechanism 15. Film inner cylinders 4a', 4b' around which films 4a, 4b are wound are retained by pairs of right and left chucking arms 19a, 19a' and 19b, 19b' via chucking cones 17a, 17a' and 17b, 17b'. One side chucking arms 19a, 19b are moved forward/rearward by screws 22a, 22b rotated by forward/rearward movement driving devices 21a, 21b, while the other side chucking arms 19a', 19b' are moved forward/rearward by forward/rear ward movement mechanisms 20a', 20b' moved by constant pressure.</p> |
