ABSTRACT:
A method of and apparatus for treating with a liquid a sheet of flexible photographic material having a photographic emulsion on one face thereof are described. The sheet of photographic material is introduced into a processing vessel (2) from above the liquid in the vessel and into the liquid with the other face of the photographic material directed to the inner wall of the vessel and the emulsions surface directed to the interior of the vessel. The sheet is driven along a curved endless path within the vessel by passing the sheet through the nips between at least one pair of driven rollers (9 and 12, 13 and 14) and is guided so as substantially to follow the inside wall of the vessel (8) during its passage through the liquid, whereby the emulsion surface cannot come into contact with a stationary part of the vessel and will not therefore be damaged during the treatment in the liquid. The driving and guiding are carried out for sufficient time for the treatment to be completed, whereupon the sheet is removed from the vessel through an outlet comprising a pivotably mounted guide member (17).
