ABSTRACT:
An apparatus for the processing of photographic sheet material comprises a plurality of treatment cells (12.sup.1, 12.sup.2, 12.sup.3) mounted one beside another to define a substantially horizontal sheet material path (14). Each cell comprises a housing (16) having a sheet material inlet (18) and a sheet material outlet (20) each being closed by a rotatable path-defining roller (28) biased into contact with a reaction surface (26) to form a nip (30) there-between through which the sheet material path (14) extends. The apparatus is characterized by sealing means (33) to seal each path-defining roller (28) to the housing (16) and means (36) to define a static liquid level (S) above the nip plane (P).
