Abstract:
A method of applying a fluid coating onto a substrate, wherein the substrate has a first surface on a first side thereof and a second surface on a second side thereof, and wherein the method comprises:providing relative longitudinal movement between the substrate and a fluid coating station; forming a fluid wetting line by introducing, at an angle of from 0 degrees through 180 degrees, a stream of fluid onto the first surface of the substrate along a laterally disposed fluid-web contact area at the coating station; and creating a main attractive electrical force on the fluid from an effective electrical field originating from a location on the second side of the substrate that is substantially at and downstream of the fluid wetting line in order to attract the fluid to the first surface of the substrate, wherein electrical charges which may reside on the second surface of the substrate do not constitute the main attractive electrical force.
