ABSTRACT:
Individual photographic films are removed from a composite film comprising a flexible carrier strip or strips to which the films have been adhesively bonded along one edge or both edges during the production of reprint photographs, by inserting a deflector under the film while bending the carrier strip around a corner to stretch the adhesive, thereby separating the film from the carrier strip.
The apparatus employed comprises an elongated frame mounting the composite film, drive means for driving the composite film the length of the frame, guide means including a corner for guiding the movement of the film, and deflector means positioned adjacent the corner for insertion under the film and moving it angularly with respect to the carrier strip as the strip moves around the guide corner, thereby separating the film from the carrier strip.
