摘要

A spray coating apparatus for spraying paint on a vertically moving web is designed to provide an overspray area on each side of the web. In order to remove the oversprayed paint, a pair of liquid film forming boards are located on both sides of the web. Each liquid film forming board is provided with a cleaning liquid supply device along the top edge thereof and a plurality of parallel vertically extending protrusions thereon for forming a downwardly flowing continuous liquid film for removing the oversprayed paint.
