ABSTRACT:
Apparatus for processing photographic sheet material includes a pair of rotatable squeeze rollers mounted one above the other to define a nip through which the sheet material passes, and a pressure roller resting on the upper roller periphery generally opposite the lower roller for biasing the upper roller against the lower roller solely by the force of gravity on the pressure roller. Thus, the biasing force on the squeeze rollers is uniform along their length. Preferably, a plane passing through the axes of rotation of the two squeeze rollers is tilted slightly forward in the feed direction of the sheet material from a vertical plane passing through the lower roller axis and the axis of the pressure roller is situated between the two planes. The pressure rollers each have a radially outward layer of elastomeric material thereon.
