ABSTRACT:
Helical processing paths are known for use in photographic processing apparatus. However, in known arrangements, the material to be processed is transported in a generally longitudinal direction along the helical path. Described herein is an improved path arrangement in which a spiral processing path (10) is utilized. The spiral processing path (10) is connected between an inlet (A) and an outlet (B), and forms a compact unit in which the material to be processed is transported with its edges in substantially in the same plane.
