Abstract (en)

[origin: DE19829490A1] The invention relates to a method and device for improving the coating surface of the coating slip deposited on a strip of body paper (8, 23). An anionic aqueous coating slip and anionic paper are thus provided with an opposite electric charge by an electric charging device, whereby the dispersed coating slip is attracted to the oppositely charged paper (8, 23). The electric charging device consists of corona generators (13, 17) or a direct current voltage source (9) that is connected to the paper (8, 23) and coating slip via electrodes (5, 5a, 7, 7a).
