Method and apparatus for plasma surface treatment of a moving substrate

摘要

Method and plasma treatment apparatus for treatment of a substrate surface (1) using an atmospheric pressure plasma. An atmospheric pressure plasma is provided in a treatment space (5) between a first electrode (2) and a second electrode (3). Furthermore, a substrate (1) and a mask web (7) in contact with the substrate (1) are provided. A plasma generating power is applied to the first and second electrode (2, 3) for treatment of surface areas of the substrate (1) exposed by the mask web (7), in which the substrate (1) and mask web (7) are moved synchronously through the treatment space (5).
