Abstract
Cut lengths or segments of photographic strip material, particularly photographic film, are stacked as they are discharged from a photographic film cutter. The device for stacking the cut lengths includes a tray, an arm, a base, and a guide. The base is connected to the film cutter, and supports the film tray with the first end of the tray positioned closely to the discharge end of the film cutter. The arm is positioned in generally overlying position with respect to the tray and is pivotally connected to the tray at the second end of the tray furthest from the discharge end of the film cutter. The arm preferably has a "W" shaped cross section which provides two lines of contact with the cut lengths of film which are deposited between the tray and the arm. The guide provides a guiding surface parallel to the path of the cut lengths along their front edges. The guide may take a plurality of positions to accommodate films of different widths. In addition, the tray may be mounted in a plurality of different positions with respect to the base to accommodate even further variation in film widths. Removal of the cut lengths of film is from the rear rather than from the front of the film …
