Abstract
The method is for applying a coating on a paper substance. A paper moves over a set of rollers. A coating is applied with a coating applicator that has ultrasonic transducers to vibrate the coating to reduce the viscosity of the coating. A downstream blade has an ultrasonic transducer in operative engagement with the blade. The vibrating blade is applied to the paper for scraping off excessive coating from the paper.
