ABSTRACT:
A motion picture apparatus and method for the advancing motion picture film through the apparatus sequence by forced air. The film is initially placed into successive looped configurations 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 loop through a projection pathway. Vacuum pressure is also applied to the film through a gate to secure the film to a 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.
