ABSTRACT:
A motor drives a film strip take-up reel to draw moving picture film from a freely rotating film supply reel through a film cleaner including a pair of oppositely rotating brushes also driven from said motor. The brushes are disposed on aligned and parallel shafts disposed at a level below that of the supply reel and above that of the take-up reel; with the film following a path generally downwardly from the supply reel about the lower portion of the cleaner brush closest to the film supply reel, up between the cleaner brushes and over the upper portion of the film cleaner brush closest to the film take-up reel, and thereafter generally downwardly onto the film take-up reel. The film path so taken by the film provides for an appropriate tension on the film which in turn insures efficient and proper film cleaning.
