Abstract
Method and apparatus for dispensing coating material on a moving substrate, such as a paper or cardboard web or the surface of a roll or the like, wherein the coating material is introduced into the coating apparatus before a coating nip and applied to the substrate through a slit of the coating apparatus directly onto the surface of the moving substrate. The coating nip and slit of the coating apparatus are formed so that a coating material smoothing member of the coating apparatus is directly supported against the moving substrate in a manner such that the free flow aperture of the slit at the coating nip is confined by the moving substrate and the surface of the smoothing member.
