Curtain coating method and apparatus

摘要

The present invention is a method and apparatus for use on a curtain coating apparatus. In a curtain coater, edge guides (12) guide the free falling curtain from the hopper lip to the substrate to be coated. Lubricating liquid (15) is introduced near the hopper lip from the top of the edge guide (12). The present invention is a method and apparatus for introducing lubricating liquid (15) as close to the hopper lip as possible while avoiding any turbulence in the flow of the lubricating liquid (15).
