B61816519 ABSTRACT OF THE DISCLOSURE A coating apparatus is disclosed for applying a coating onto a surface of a moving web. The apparatus includes a backing member which defines a perforate surface such that when the member is connected to a source of partial vacuum, the web is drawn towards the perforate surface of the member. A coating blade is disposed adjacent to the backing member such that the blade urges the web towards the perforate surface. A permeable belt extends around the backing member with the belt being disposed between the web and the backing member such that when the source of partial vacuum is connected to the backing member, air flows through the belt and the perforate surface for drawing the web into close conformity with the belt. The belt and the web then move together in the same direction for inhibiting the buildup of deleterious material adjacent to the blade that would otherwise remain adjacent to the blade causing marking of the coating applied to the surface of the web by the blade.
