ABSTRACT:
Systems and methods in accordance with the invention clean particulate matter from photographic film using water without impairment of image bearing portions of the film or retention of substantial water in the film. Water formed into thin sheets is directed at high velocity or with mechanical augmentation against the film in directions at least partially opposite to the direction of film movement. Alternatively or successively, the film passes through water removal stations where dry air is blown onto the film and adjacently drawn off with entrained water in successive alternating flows. The film may be further dried of absorbed moisture in an associated environmental chamber having multiple loops before being wound up on a takeup reel.
