Coating solution distribution apparatus

摘要

A coating method and apparatus for applying a liquid coating solution containing suspended particulates to a moving web which eliminates areas of stagnation in the reservoir pan thereby resulting in a relatively even application of the particulates to the web. The web is continuously passed through the reservoir pan while supported on a rotatable backing drum. The liquid coating solution is delivered to the coating pan through a distribution conduit a distribution conduit disposed within the reservoir pan generally parallel to the discharge weir of the reservoir pan. The distribution conduit includes a plurality of spaced apart orifices therein to deliver the liquid coating composition in a pair of end streams and a plurality of intermediate streams traveling toward the discharge weir. The distribution conduit is fed from both ends thereof resulting in the end streams flowing at a greater velocity than the intermediate streams.
