ABSTRACT:
A shutter assembly is coupled to a rotor of a rolling loop mechanism for use in a cimematographic film projector. The shutter assembly includes a plurality of curved plates, each of which is positioned about a gap in the rotor such that the plate is connected by its ends to the sides of the gap and extends inwardly of the rotor to provide clearance for a rolling loop of film. A stator is provided to combine with the rotor for guiding the film past an aperture and as a shutter plate passes the aperture projection light is cut off from the aperture.
