ABSTRACT:
A method for coating a web with a coating material by applying a metered coating material onto the web and smoothing the applied coating material evenly onto the web with a flexible predoctoring blade. The coating material is applied to the web by the predoctoring blade in the form of a high velocity laminar flow in advance of the predoctoring blade. The coating mix is fed to a stem part of the flexible blade via an exit channel having a narrow opening. The loading of the flexible blade, acting as a smoothing device, is controlled in a cross direction of the web in order to control the cross directional profile of the applied coating web. The feed velocity of the laminar flow is at least one small m/sec.
