Abstract
Abstract Deflection correction metering bar assembly for metering coating on a web. The assembly includes a rod holder having a recess extending along its top portion, a metering rod mounted in said recess, deflection correction bars for said rod holder, carrying jacking screws deflecting the rod holder in horizontal and vertical planes and holding the rod holder against sagging vertically or deflecting horizontally. A fluid passageway leads through the rod holder to accommodate the passage of temperature control fluid therethrough, to prevent coating from building up on the metering rod, and maintain an even coating on the web.
