Abstract
A method and apparatus for applying a coating composition onto a moving web especially a paper web, in which an excess of said coating composition is applied to said web. The web thereafter passes smoothing means to uniformly regulate the final thickness of the coating and simultaneously to remove the excess coating composition. This smoothing operation is performed under an adjustable partial vacuum. The removed excess coating composition is recirculated without being mixed with the coating composition within the application area and is mixed with fresh coating composition before reuse within the process.
