ABSTRACT:
It is well-known to use grooves to guide photographic material through processing apparatus. However, there is a tendency for debris to accumulate in the bottom of the grooves. Furthermore, the machining operation needed to form such grooves is complicated in particular where bends and changes in direction are required. Described herein is a guiding arrangement in which pairs of parallel plates (20, 22, 24, 26) are used to define a gap (30) through which material (40) is transported. The arrangement comprises an upper plate pair (20, 22) which is arranged to be offset with respect to a lower plate pair (24, 26), the plates in each pair being parallel to one another.
