ABSTRACT:
Apparatus for processing sheet material in a bath of liquid comprising a pair of drivable endless bands between which the sheet material is held to carry it through the liquid bath in a container. The bands are permeable to allow access of the liquid to the sheet and follow a path between stationary scraper bars which guide the bands to follow a slightly sinuous path, thereby ensuring contact between the bands, and which press the liquid through the permeable bands. Conveniently the bands, which are of woven material and driven by splined rollers, follow a generally U-shaped path within the container. For processing X-ray films in piece or strip form a series of processing units are used side by side with a common drive system.
