Abstract
A mechanism for automatically taking up film strip material on to a driven spool comprises a fixed guide to direct the film around the spool, and a pivotally-mounted guide for directing the film back on to itself so the leading end is entrained between the spool and a remote portion of the film. The mechanism is contained within a cassette having an inlet slot for directing the film through nip rollers to the fixed guide.
