Abstract

An apparatus for applying a treatment liquid to a web moving in a predetermined web-travel direction has an applicator element having a surface extending transverse to the direction and positioned to contact the moving web. The liquid is applied to the surface such that the liquid is transferred to the moving web where the moving web contacts the surface. A shield directly engages a portion of the surface between the web and the surface so that where the shield extends between the moving web and the surface there is generally no transfer of the liquid from the surface to the moving web. Formations on the shield conduct the liquid away from edges of the shield.
