FILM CASSETTE PROCESSOR HAVING REVERSE INCLINED DOCTOR BLADE

摘要

6008 A doctoring surface conformation for applicator nozzle structures in photographic film cassette contained processors by which a coating of processing fluid is deposited on exposed film strip moving in a given direction of film advancement. The conformation includes a first doctoring surface extending from adjacent a trailing portion of a nozzle opening, when viewed in the given direction, and converging in the given direction toward the film strip. Terminating by a given distance from the film strip is an edge of the first surface which enables such surface to trap particles of at least a predetermined size carried by such film strip. Contiguous with the terminating edge is a second doctoring surface which is constructed and oriented relative to the first surface and film strip so that the processing fluid remains in constant contact therewith for providing a preselected fluid thickness above the film strip which is greater than the given distance of the terminating edge for eliminating wakes in the fluid coating caused by particles being trapped by the first surface.
