Abstract
An ultrasonically assisted coating method for applying a smooth layer of coating material on a surface of a moving web are disclosed. A coating material is applied onto one web surface. An ultrasonic energy generator excites the line of initial contact between the coating material and the web at a uniform ultrasonic intensity selected in combination with the properties of the coating material. The coated web has a thin, uniform crossweb thickness with low thickness variations.
