ABSTRACT OF THE DISCLOSURE Apparatus for maintaining a relatively placid pool of liquid coating material in the trough between two nipped rolls comprises a pair of deckles, one disposed near either end of the nipped rolls, each of the deckles having an edge generally conforming to a segment of the adjacent roll to effectively form an end of the trough formed by the rolls. At least one of the deckles has one or more openings which permit the liquid coating material to flow laterally out of the trough and through the deckle at a rate proportional to the depth of the coating material in the trough. Controlling the lateral outward flow of material from the trough stabilizes both the turbulence of the liquid coating material in the trough and the surface condition of the coating material.
