Abstract
Method and apparatus for reducing frictional drag on a strip of photographic film moving in a film cassette between a pressure pad and a fluid processor nozzle, and for more effectively controlling the processing fluid thickness on the moving film. Formed on such a nozzle is at least a pair of pressure pad engaging surfaces spaced laterally beyond the film's longitudinal margins so as to cooperatively engage with a pair of generally correspondingly spaced nozzle engaging surfaces of the pressure pad. Between the nozzle engaging surfaces on the pressure pad is at least one raised film supporting member. Such film supporting member can support the film in a predetermined spaced relation to the nozzle so that the film need not engage the nozzle while spacing the film's edge rails from the remainder of the pad.
