Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
In a surface application photographic processing device for processing the exposed photosensitive surface of a web or sheet of material by applying thereto a layer of processing solution, the combination comprising: a container for holding a processing solution; a plurality of spaced apart, rotatably driven rollers partially immersed in the processing solution for transporting a material through the processing device and simultaneously applying the processing solution to one surface of said material in engagement with said rollers for processing said material during its transport; and a flexible blanket supported by said rollers for engaging the opposite surface of said material and guiding said material with said one surface thereof pressed and held into intimate engagement with said rollers.
Claim 2
Dependent Claim
