摘要：
A method and apparatus for applying a uniform coating to a moving paper web by utilizing a coating applicator with regional cross-machine zones from which coating quality or excess coating can be monitored and analyzed. As the coating conditions vary between regional zones, upstream liquid coating flow parameters can be varied for a particular region to render uniform coating profiles across the entire machine-direction of the web.
