Abstract

An apparatus for wet treatment of sheets or strips of photographic material has a small-volume treating chamber bounded by pairs of advancing rollers at its inlet and outlet ends. A lower wall of the chamber extends between the lower rollers of the pairs of advancing rollers and sealing lips bridge the gaps between such lower wall and the respective lower rollers. Treating liquid is admitted laterally into the chamber, transversely of the path of advancement of photographic material and at about the level of such path.
