ABSTRACT:
A film processor wherein two partitions divide the housing into a centrally located chamber, a first compartment between the film-admitting inlet and the chamber and a second compartment between the chamber and an outlet for evacuation of processed film. Each partition has a one-piece plastic flow restrictor with a horizontal slot for the film. The flow restrictors extend into the respective compartments and into immediate proximity of the peripheral surfaces of advancing rolls which are installed in the compartments to advance the film from the inlet into the chamber via one of the slots and from the chamber toward and into the outlet by way of the other slot. A system of pumps delivers processing liquid from a reservoir into the chamber at such a rate that the liquid level is above the slots. The liquid which escapes from the chamber into the compartments by way of the respective slots is returned into the reservoir.
