ABSTRACT:
A motion picture apparatus and method for intermittently advancing motion picture film by forced air. The film is initially placed into successive loops formed by a cam-driven flipper. The loops and thus the film are advanced through the projector or camera pathway by a forced air blower which propels the successive loops through a projection pathway. Vacuum pressure may also be applied to the film through a gate to secure the film to the gate with linearly arranged register pins steadying the film over a projection aperture. The film is rewound through the projector by a motorized rewind with a positive pressure applied to the film through the gate.
