Abstract
Apparatus for processing photographic material comprises a succession of processing regions formed by inclined planes extending between sets of rollers. As the material is driven up the planes with its emulsion side down, wash solution flows down beneath it. The length of each plane can be different so that the material is washed for different times in each region, achieving chemical equilibrium in the final region before passing on to the drying stage.
Claims28
Apparatus for processing photographic material, comprising a plurality of successive processing regions, each of which is defined by a surface inclined to the horizontal and disposed between a spaced-apart pair of guide means arranged to direct the material from one region to the next over the inclined surface, at least part of the surfaces being curved such that both sides of the material are subject to the processing solution and means for supplying processing solution to at least one of the regions so that it flows along the associated surface beneath the moving photographic material, thereby effecting processing.
A method of processing photographic material, wherein the material is passed through at least two successive processing regions formed by inclined surfaces between spaced-apart guide means, at least part of one of the surfaces being curved such that both sides of the material are subject to processing solution, the processing solution being supplied to at least one of the surfaces such that it flows beneath the moving material, thereby to effect the processing.
