ABSTRACT:
A film-feeding mechanism is provided having at least one conveying claw for intermittently transporting a motion picture film that is provided with perforations which extend parallel to the lateral edges thereof. Said film-feeding mechanism further includes at least one locking claw whose tips engage into a perforation in order to ensure picture steadiness, and a film-guiding device that aligns the motion picture film. Lateral film-guiding elements of the film-guiding device are disposed so as to be at least partly movable relative to the lateral edges of the motion picture film.
