A continuous web having a first surface and a second surface is coated with a coating powder by allowing the web to move between a first and a second electrode, which are in different potentials and are located on the opposite sides of the web, applying the coating powder on the surface of the web by utilizing the difference in the electric potential, and finishing the coated surface of the web. Both surfaces of the web are coated essentially simultaneously by using oppositely charged electrodes.
