Abstract
Exemplary embodiments of the present invention include two half shells that can be operably joined together, in whose walls pouches are provided. Two elements, approximately formed as ladders, each include first transport rollers, the two ladderlike elements being configured for insertion in the joined together half-shells. The first transport rollers are disposed on the respective ladderlike elements in such a way that upon insertion of the ladderlike elements into the joined together half-shells, the transport rollers fit into the pouches of the walls of the respective half shells. Exemplary embodiments also include a central element which, after the insertion of the two ladderlike elements, can be placed between the two ladderlike elements to maintain the two ladderlike elements in position and which, together with the respective ladderlike elements and the respective walls of the half-shells, defines a conduit for photographic material to be developed. This conduit extends between each of the ladderlike elements and the central element, and between the walls of each of the half-shells and the central element. Second transport rollers are provided on the central element which, a…
