ABSTRACT:
A film spool comprises a spool core having a slot for receiving a film end, a cantilevered beam supported at only one end inside the slot to prevent movement of the beam along the slot and to allow the beam to be swung laterally within the slot, a film engagement protrusion projecting into the slot from either one of the spool core or the cantilevered beam to engage a film end within the slot, and a film stripper protrusion projecting into the slot from whichever one of the spool core or the cantilevered beam the film engagement protrusion does not project from to disengage a film end from the film engagement protrusion when the beam is swung laterally within the slot.
