Abstract: A universal film thrusting cartridge includes a tab connected to a fixed diameter spool core and connectable with a filmstrip of optional length, the tab being sized for use with the shortest filmstrip and trimable to fit longer filmstrips so that when wound within the cartridge the film roll has a prescribed outer diameter at the leading outer end. The trimable tab avoids different core sizes for each filmstrip length in order to obtain the prescribed outer roll diameter needed to match the cartridge wall and allow thrusting of the film out of the cartridge on reverse winding of the spool.

Abstract: A leader card attachable to a photographic filmstrip having a lead end with at least one aperture. The leader card includes (1) a piece of material having a tab portion and (2) at least one hook secured to the material. The hook is sized to be extendible through the aperture to secure the leader card and lead end of the filmstrip together. The tab portion inhibits the hook from being removed from the aperture.
