Abstract
The present invention is an apparatus for curtain coating a composite layer formed from a plurality of coating compositions onto a moving receiving surface. Edge guides comprising two thin, parallel and closely spaced wires maintain the horizontal extent of the free falling curtain. A flushing and lubricating liquid is supplied to the edge guide. The present invention comprises a distribution body for delivering the flushing and lubricating liquid in laminar flow without initiating stationary waves in the curtain that lead to objectionable coating nonuniformities. The distribution body allows for replacement of the wires without its removal or disassembly. A horizontal conduit near the top of the curtain has an outlet face in contact with the wires that tapers in the upward and downward directions to horizontal edges. The wires pass across the outlet opening within its horizontal diameter. The upper edge of the outlet face positions and supports the wires.
