Apparatus for the wet processing of photographic sheet material
A wet processor comprises a plurality of cells (12, 12', 12") mounted one above the other in a stack to define a substantially vertical sheet material path (20) through the apparatus. Each cell comprises a housing within which is mounted rotatable roller (28) biased towards a reaction surface (31) to define a roller nip (36) there-between through which the sheet material path extends and associated sealing means (38, 39) serving to provide a gas- and liquid-tight seal between roller (28) and reaction surface (31) on the one hand and a wall (14) of the housing on the other. The roller (28) is a drive roller. Alternatively or additionally means (19, 21) are provided for connecting each cell to adjacent cells in the stack in a closed manner. By this simple construction, treatment liquid in one cell is not contaminated by contents of the adjacent cells. Furthermore, consumption of treatment liquids is reduced by reducing the evaporation, oxidation and carbonization thereof.
