Definitions

  • the bath containing said solution should have a shape such that the volume of solution held between the bath and the roller is small.
  • This arrangement has the disadvantage that exhaustion of the small volume of processing solution can lead to undesired effects, for example uneven processing.
  • FIGS. 6 and 7 the photographic material 15 passes between driven nip rollers 16, into a guide 17 which dips below the surface of a processing solution 18 contained in the trough unit 20, between the nip of rollers 19 and through further guides and rollers, as shown, finally leaving the apparatus by passing through squeegee rollers 21.
  • FIG. 7 shows the flow pattern of the solution 18 which enters at inlet 22, passes through each trough through connecting ducts 23 and leaves by outlet 24.
  • a photographic processing apparatus for processing an elongated strip of photographic material comprising in combination:
  • a receptacle whose interior contains a plurality of parallel partitions extending transversely, and spaced apart along the length, of said receptacle to provide a plurality of troughs joined together in spaced parallel relation and arranged so that a volume of processing solution introduced into the first of the series of troughs will flow into and through successive ones of the troughs and be discharged from the last one of the series, said receptacle being inclined downwardly in the direction of flow of said processing solution to enhance such flow from trough to trough;
  • At least one rotatable roller extending longitudinally of each trough and having its surface dipping into the processing solution in its respective trough for guiding a strip of photographic material across said troughs in succession and applying processing solution to at least one surface thereof;
