ABSTRACT:
A space-saving, efficient wash tank is provided in which a plurality of compartments are serially connected through narrow channels to provide a continuous processing path, and wash water is supplied to the path through a selected compartment, whereby a strip of photosensitive material is washed with the water during its passage through the path. This wash tank ensures efficient washing and water saving when the selected compartment has a smaller volume than the remaining compartments or when the selected compartment is substantially emptied of the water during a quiescent period, or bath. Wash water flows in counter flow to the travel direction of photosensitive material during operation and is drained from the lowermost compartment at the end of operation.
