ABSTRACT:
A photographic material clamping apparatus includes a rotatable drum that has a longitudinally extending central axis, a longitudinal opening offset from the central axis, and a plurality of radial openings extending between the drum surface and the longitudinal opening. A cover member overlies the plurality of radial openings. A counterweight is positioned in the longitudinal opening and is connected to the cover member. Spring means act on the counterweight to urge the cover member towards the surface of the drum to grip a piece of photographic material inserted between the cover member and the drum.
