ABSTRACT:
A reel unit for supply and take-up of film from at least one motion picture projector includes an upright support column and a plurality of film platter-support arms that extend generally horizontally from the column at vertically spaced positions. The arms are alternately offset laterally from one another to facilitate access to film on platters below the top arm. Each arm carries a platter drive hub provided with upwardly projecting drive pins that engage in openings in the platter so that the platter can be lifted off the arm. This allows the platters to be interchanged between different arms. Film take-up and pay-out cores can be interchangeably mounted on the platters so that any one platter can serve as a supply platter or a take-up platter irrespective of its position on the column. For the same reason, the column carries, in association with each arm, a set of rollers for guiding film being paid out from a platter on that arm or being wound onto the platter.
