DEVICE FOR THE PLASMA TREATMENT OF OBJECTS, IN PARTICULAR IN STRIP FORM

A device for the plasma treatment of an object, in particular in strip form, has an electrode (7) and a counterelectrode (8) of electrically conductive material and an alternating high-voltage generator (17), which is designed and connected so as to cause a gas discharge between the electrode (7) and the counterelectrode (8) by means of an alternating high voltage. In this case, the electrode (7) and the counterelectrode (8) are arranged next to one another in a contact casing (5), which has a roller (1), which is mounted rotatably about a roller axis (2) and is intended for contacting the object to be treated. The contact casing (5) has an outer layer (9, 10) of dielectric material (6), which covers the electrode (7) and the counterelectrode (8) and, between the electrode (7) and the counterelectrode (8), is connected in series with the gas discharge in order to hinder the gas discharge dielectrically, and arranged above the electrode (7) and/or above the counterelectrode (8) there is a linear ignition electrode (21, 22) of electrically conductive material, which is separated from the electrode (7) and the counterelectrode (8) by the outer layer (9, 10) and at the outer circumference of the contact casing (5) is exposed.
