Abstract: A unit for developing exposed photographic paper is disclosed, which has several baths arranged one after the other and a drying chamber, through which the photographic paper runs continuously for developing and drying. The photographic paper is passed as a continuous sheet through each bath and the drying chamber in spiral form and with several coils. A storage unit is provided for the continuous photographic paper at least at the feed end of the unit.

Abstract: There is disclosed a direction-changing roller for suspension frames of photographic material developing machines, over which the photographic material to be developed is guided in a meandering path. The roller has a cylindrical roller body on each end of which there is arranged a respective collar-shaped flange. There are further rollers inserted in the roller body. The surfaces of the further rollers are flush with the outline or surface of the roller body. Each further roller is mounted to be freely rotatable about an axis extending perpendicular to the axis of rotation of the direction-changing roller and radially offset from this axis of rotation.
