The invention is based on the problem of improving an apparatus for modifying the surfaces of webs using a device for generating plasma, in particular of ensuring that uniform plasma is created. For this purpose, the invention proposes to round the edges (4, 5) of the electrode (1) such that the flow in this region does not become turbulent. In addition, the media flow is conducted through the hollow electrode (1), achieving cooling of the same. The counter electrode (8) is preferably arranged in the hollow electrode (1). |
