ABSTRACT:
Processing apparatus for spreading processing fluid uniformly over photochemical layers on one or more photographic sheets by progressive pressure applied by rolling surfaces provided on large diameter calendering members. To achieve the large diameter rolling surface, the calendering members are defined by cylindrical sectors having a circumferential length corresponding to the length of sheets to be processed and supported by means effective to bring the respective cylindrical surfaces of both members into contact with opposite sides of the processed sheets. In one embodiment, the calendering members are semi-cylindrical, whereas in another embodiment the members are quadrants of cylinders.
