ABSTRACT OF THE DISCLOSURE A multipurpose audio/visual film cassette including supply and takeup spools is disclosed 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 supplyspool and interwound with the film strip to pass through a separate path. A stripping and separating web is coupled at least on one end to the supply spool and extends directly to the takeup spool in a third path with the web being arranged to overlie the side of the film strip on which processing fluid is deposited. The stripping and separating web is wound in convolutions between the fluid covered side and the audio tape to prevent adherence of the audio tape to the film strip and to strip a negative emulsion layer from the film strip after processing.
