Abstract
An apparatus for processing sensitive materials has a tank in which film containing a sensitive material is conveyed, the film passing through a processing bath while guided by conveying rollers, and at least one wiper coming into contact with at least one of the conveying rollers facing to a film surface of the sensitive material. A flow of processing solution is produced by at least one inlet or jet in the region where contact occurs between a wiper and a conveying roller, so that any material wiped off the roller is removed away from the contacting region.
