ABSTRACT:
An apparatus for liquid-processing light-sensitive sheets comprises a processing dish preferably with a horizontal intermediate bottom. The upper side of the intermediate bottom constitutes the lower, and the underside of a lid covering the dish the upper, wall of a passage-gap through which the sheets are transported by pairs of conveying-and-squeezing rollers. The downstream dish sidewall, taken in sheet-transportation direction, is provided near its foot with a horizontal row of injection-nozzles for processing liquid. The dish sidewall opposite the nozzle-bearing sidewall bears a horizontally extending ledge or appropriate flow-reversing configuration effecting 180.degree. reversal of the direction of liquid flow from underneath the intermediate bottom to above the profiled bottom-surface and toward the nozzle-bearing sidewall, generating a liquid stream through the passage-gap in the sheet-transportation direction. The bottom surface possesses a profiling comprising gable roof tile-like faces extending transverse to the sheet-transportation direction.
