Apparatus for, and method of, film strip processing using doctoring means moving in a direction opposite to the film strip movement

Abstract From the Canadian patent

A method and apparatus for applying processing fluid to the light sensitive emulsion surface of a photographic film strip contained in a multi-purpose cassette and in which a coating of processing fluid deposited directly onto the film strip is delimited by a doctoring surface moved in a direction opposite to the direction of film strip travel during passage thereof at the doctoring surface. The doctoring surface may be the cylindrical surface of a roller or it may be effected by a portion of the film strip itself. In the latter instance the film strip is constrained to a loop-like path during processing by appropriate guide means so that one of the oppositely facing surfaces in the neck of …
