Abstract

A plasma treatment device for treating a surface with a dielectrically impeded plasma field which is generated between an electrode (16), to which a high voltage is supplied, and the surface, wherein the electrode (16) forms, with a dielectric (17) surrounding the electrode (16), a roller (6) mounted rotatably in a grip housing (1), which roller can be rolled on the surface, has an extended treatment field and enables defined and controlled plasma treatment of the surface by virtue of the fact that the roller (6) is designed such that it can be matched flexibly to irregularities on the surface and has a rolling area with elevations (19, 19′), between which interspaces (20) forming the plasma field are located.
