1000-Foot Bipack Magazine and Adapter

Users of 35-mm bipack film have been restricted to the use of 400-foot rolls of negative stock. This is because present standard photographic equipment will not handle 1000-foot rolls in the conventional-type bipack magazine. Loss of production time and excessive negative wastage, as well as severe photographic limitations, are the result. — An adapter has been developed at Cinecolor Corporation which permits the use of 1000-foot rolls of negative film in side-by-side position, rather than one over the other. This arrangement gives an attractive and convenient operating assembly, which keeps the center of gravity low. It eliminates the need for unwieldy and top-heavy blimps. The adapter causes the films to be changed from a side-by-side to the superimposed emulsion-to-emulsion relationship required in bipack photography. In the Cinecolor arrangement, the 1000-foot rolls are fed from a single 70-mm magazine into the adapter. Two individual 1000-foot magazines can be used equally well.
