ABSTRACT:
A photographic slide mounter includes a film advance mechanism which advances a photographic film web along a film track to insert the end of the film web into a photographic slide frame. The film advance mechanism includes a guide track parallel to the film track and a carriage which is movable on the guide track. A film advance pawl is connected to and movable with the carriage. The pawl engages sprocket holes in the film to advance the film as the carriage is advanced toward a first end of the film track. A drive mechanism advances the carriage toward the first end of the guide track during one portion of an operating cycle, and returns the carriage to the second end during another portion of the operating cycle. The film advance mechanism includes a breakaway mechanism for disconnecting the carriage and the drive mechanism when resistance to advancement of the carriage exceeds a predetermined amount. This prevents the pawl from tearing the sprocket holes of the film in the event the film, for some reason, is resisting movement.
