Abstract
A device for processing a photographic film through a moistening chamber and a drying chamber has a transition zone where a pair of counterpositioned squeegee rollers is located, of which the upper roller contacts an emulsion carrying surface of the film and the lower roller engages the back surface of the film. The film is advanced to the transition zone from the moistening chamber by a pair of transporting rollers rotated with a predetermined speed. The lower squeegee roller is rotated with a speed exceeding the speed of rotation of the transporting rollers so that a predetermined tension is applied only to the back side of the film to avoid a potential damage to the emulsion carrying surface of the film.
