Abstract
A photographic sheet material processing apparatus comprises a pair of processing rollers, means for feeding sheet material to be processed between the processing rollers. Processing liquid distribution means supply processing liquid to the rollers. The processing liquid distribution means comprise an open-topped distributor channel positioned adjacent the processing rollers, and means for feeding processing liquid to the distributor channel along the length thereof. The distributor channel is formed with a plurality of apertures through which processing liquid passes to the rollers. Overflow means associated with the distributor channel maintain a constant liquid head therein.
