Abstract
In a coating apparatus of slide bead type for applying a coating solution on a continuously-fed web, each of edge members has a edge member for regulating a width of coating solution flowing on a slide surface. A height Dg of a perpendicular wall of the edge member satisfies a condition Db≦Dg≦Ds, when Db is determined as a minimum thickness of bead formed by a coating solution, and Ds is determined as an upper limit of the upper limit of the height Dg. A distance between a web and a front end portion of the edge member is more than 100 μm.
