ABSTRACT:
Apparatus for convoluting exposed and copied photographic films on the cores of takeup reels has an advancing mechanism which transports successive films along a given path so that the leaders of successive films can be engaged by the gripper of a pivotable arm serving to transfer the leader of the film in the path toward the peripheral surface of the core of an empty takeup reel. The reel has no flanges or is provided with a single flange carrying or adjacent a fixedly mounted or movable protuberance which defines with the peripheral surface of the core a gap for the leader of the film. Once the leader has entered the gap and the takeup reel is set in rotary motion, the film is wound onto the protuberance and is thus affixed to the core. The length of the protuberance is less than the axial length of the core but exceeds one-fourth of such axial length.
