Abstract
A coating system employs a fluidized bed unit in which the porous plate is inclined to promote flow of the coating powder from the feed point to a subjacent location. Means is provided to sense the level of the coating powder at the subjacent location of the plate, and to control its discharge into the unit in response thereto. The incline of the plate minimizes the lag between the feed and sensing operations, thereby affording accurate correlation between the amount of powder introduced and the actual need.
