Abstract

A method for coating a paper or paper board web at least on one side of the web by a coating color containing pigment particles and by applying a spray technique. The method comprises at least the following successive steps: (a) the web is electrically charged by conducting the web through an electrostatic field that is created between an electrode and a counterlectrode ; (b) the web that was electrically charged in step (a) is conducted to the coating station, and (c) the web conducted to the coating station is coated at least on one side by said coating color containing pigment particles and by applying the spray technique.
