PURPOSE:To avoid cohesion between films themselves, by forming one of more than three clip blades setup within the same surface into a stationary one and the remaining blades into being free of rocking motion, while energizing them so as to separate from the stationary blade. CONSTITUTION:An intermediate clip blade 18 is installing between a clip blade 5 of a film holding device 17 and a contact part 2b. This blade 18 is rockably supported by a vertical part 3c of a support shaft 3, while a clip blade turning member 9 moves in a state of a side edge of films 20 and 21 being situated among the contact part 2b, the blade 18 and the blade 5 to be energized upward by a plate spring 19 or the like, and the blade 5 rotates left-handedly against contraction force of a spring 6, locking the film 21 between the blade 5 and the blade 8, while this blade 18 is pressed downward, holding the film 20 between this blade and the contact part 2b. And, after heating and extension, the holding device 17 is moved, making the member 9 retract, and film holding is automatically released by dint of restoring force in these springs 6 and 19.
