A method, apparatus, system, and computer program product for clearing flow disruptions in the coating applicator comprises vibrating at least a portion of the applicator to clear flow disruptions. In an apparatus embodiment of the invention, at least one vibrator is attached to a nozzle portion of the applicator for generating vibrations having a frequency of less than about 20 kHz and an intensity of at least 3 G, and a magnitude of less than 10% of a minimum nozzle slot width. A system embodiment comprises a web inspection system down stream of the applicator to detect coating defects and communicate a cross-machine location of the defect to activate vibrations at that location to clear the flow disruption.
