Abstract
A fluid applicator is provided for depositing a coating of processing fluid on a moving run of photographic film strip which includes a single fluid reservoir which comprises an integrally formed nozzle assembly which includes an opening through which processing fluid may be released and a downwardly facing doctoring conformation for expressing the desired layer of processing fluid upon the film strip emulsion. A processing fluid sealing tear tab is positioned directly upon the downwardly facing surface of the processor and is sealingly engaged therewith by a suitable adhesive material. The tear tab is provided with means attached thereto at one end for assuring removal of substantially all of the adhesive material carried by the doctoring conformation upon removal of the tear tab to thereby assure a substantially clean adhesive free surface to be presented to the film strip during the processing fluid deposition.
