Abstract
A motion picture apparatus for the projection of motion picture film which advances the film through the projection 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 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.
