Abstract
An apparatus for treating sheets of flexible photographic material with a liquid, comprises a vessel containing a liquid in which is partially immersed a driven drum, means to guide a sheet of flexible photographic material into the liquid so that the emulsion-free side of the sheet adheres to the surface of the drum; rotatable rollers located spacedly about the periphery of the drum help to keep the sheet of photographic material adhered to the surface of the drum. The vessel which contains the liquid is substantially cylindrical and is so shaped that it cooperates with the rollers in keeping the sheet of photographic material adhered to the surface of the drum. An exit part of the sidewall of the vessel above the level of the liquid therein is movable, for instance by being pivotably mounted. When this part is in an open position, a sheet of flexible photographic material emerging frm the liquid can peel away from the drum and enter an exit opening in the vessel and be guided out of the vessel.
