{PG,1 A multipurpose audio/visual film cassette including supply and takeup spools in which opposite ends of a film strip are coupled for alternate winding and unwinding during passage through a first path for film exposing, processing and projecting operations with an audio tape also coupled at least on one end with the supply spool and interwound with the film strip to pass through a separate path, and a separating web is coupled at least on one end to the supply spool and preferably extending directly to the takeup spool in a third path. The separating web is arranged to overlie the side of the film strip on which processing fluid is deposited so as to be wound in convolutions between such side and the sound tape in order to prevent adherence of the sound tape to the film strip as a result of being interwound therewith before the processing fluid has dried.
