ABSTRACT:
An apparatus for the wet processing of photographic sheet material comprises at least one treatment vessel (12, 12', 12") having upper and lower openings (17, 18). One of the openings constitutes a sheet material inlet and the other of the openings constitutes a sheet material outlet. A substantially vertical sheet material path (20) through the vessel is defined by the inlet and outlet and by a path-defining rotatable roller (28) biased towards a reaction surface (30) to form a roller nip (36) there-between through which the sheet material path extends. The path-defining roller (28) is in sealing contact along its length, with a rotatable sealing member (38). The reaction surface is preferably a further path-defining roller. The sealing of one vessel from the next and of the path-defining roller to the housing of the associated vessel is thereby achieved in a simple and reliable manner.
