ABSTRACT:
A mechanism for winding endless bands of film on a hollow hub which is open at one side thereof and has a circumferential rim. The rim is provided with a plurality of apertures and a pivotal arm with a finger thereon engages the film to introduce the same into the hub through one of the apertures to form a loop of film within the hub. A guide cam is mounted on the rim adjacent each aperture for engaging the finger when the latter is offset from the respective aperture to pivot the hub so the finger can be smoothly and directly introduced into the aperture. A drive is obtained through two electro-magnetic clutches by means of one motor. The winding spool turns opposite the unwinding spool, in order to use a clutch as both a brake or a coupling, depending on whether the spool is a winding spool or an unwinding spool.
