Abstract: A pair of drums is mounted for rotation about at least substantially parallel axes which are located in a common plane. The drums form with one another an axial gap and bodies or walls are located adjacent to the drums and define with the circumferential walls thereof a first channel section which surrounds the circumference of the drums at least in the region of the gap at one side of the plane, and a second channel section which surrounds the circumference of the drums at least in the region of the gap at the other side of the plane. The channel sections merge with one another in the gap. An arrangement is provided for circulating a treating fluid through the channel sections and into the interior of the respective drums and a feeding arrangement feeds the photographic material into the channel sections so that it sequentially moves through the first and thereupon through the second channel section and becomes treated by contact with the treating fluid.

Abstract: A plurality of strip-shaped material-engaging elements is moved by cranks in a path in which the elements sequentially move towards the material to be transported, engage it, move with it through a predetermined distance, and then release it and recede from the material.
