Abstract

An improved paper coating applicator has a body portion defined by forward and rearward relatively movable walls defining a chamber therebetween with an elongate opening thereto positionable generally below, adjacent to and transversely of a paper web, the chamber receiving coating liquid and directing the same generally upwardly through the opening and onto the web. According to one aspect of the improvement, the chamber and a distribution header for introducing coating material therein are of a design enhancing a very uniform application of coating material onto the web. In another aspect, a unique seal structure provides a secure, fluid tight connection between the front and rear walls.
