ABSTRACT:
Method and apparatus for limiting unwanted vibration-induced variations in coating thickness of coating materials deposited on a moving web by an extrusion-type coating applicator employs a vibration generating electro-mechanical transducer coupled to the applicator that produces mechanical vibrations having an amplitude and frequency that produce a reduction in the magnitude of the vibrations causing the unwanted web coating thickness variations.
