Abstract
A film transparency severed from a photographic film web is inserted into a slide mount to prepare a photographic slide. The present invention relates to an "in-plane" film pusher for inserting a severed film transparency into a slide mount. The apparatus includes a pusher assembly having a movable pusher support and a pusher with a front grooved surface designed to engage a trailing edge of the film transparency. The pusher is alternately supported by the movable pusher support between a retracted position below a film plane and an engaging position aligned with the film plane. In operation, the pusher is moved to the engaging position to engage the trailing edge of the film transparency and then is advanced with the movable pusher support toward the slide mount to push the film transparency into the slide mount.
