Abstract

PURPOSE:To deflect the narrow part at the tip of a film forcibly and to transfer the film, by providing taper rollers which press the film to the outside circumference of a spool. CONSTITUTION:A spool 1 has pawls 2 in positions where perforations 8 of a film 7 wound around the circumferential face of the spool 1 should be engaged with pawls 2, and taper rollers 41 and 42 have a large diameter in the center and have a small diameter in both end parts. The narrow part at the tip of the film 7 is deflected by the force directed toward the side by this taper.
