ABSTRACT:
Disclosure of an electrode arrangement (1) as high voltage electrode for continual plasma treatment or plasma coating of web material with several knife electrodes (3) arranged at a right angle to any transport direction of the web material and essentially located parallely to each other which is characterized by the fact that the distances (a−e) of adjacent knife electrodes (3) vary. In tests it has turned out that a more uniform coating result or, respectively, treatment result can be achieved with such an electrode arrangement than with comparable arrangements in which the knife electrodes are arranged equidistant. Preferably, the distances (a) between adjacent knife electrodes (3) are larger at the edges of the electrode arrangement (1) than the distances (e) between adjacent knife electrodes (3) in its center.
