ABSTRACT:
A supply magazine for use in an apparatus for removing individual film that has been placed within a light-tight pouch having a leader secured to the leading edge. The magazine has a base which receives and retains a stack of sheet film within the light-tight pouch, and a cover secured to the base which can be rotated between a closed position and an open position. A take-up spindle is rotatably secured within the base for winding of the pouch thereon. The improvement comprises a lever arm for biasing the leader toward the spindle which cooperates with hook provided on the spindle when the cover is in the closed position. The lever arm includes a clamp pad which has a configuration which forms a resistive wall section in the leader when the magazine is in the closed position such that when the spindle is rotated, the hooks will engage the leader at the resistive wall section allowing the pouch to be wound around the spindle.
