Abstract
A device and a method for at least partial removal of electric charges from dielectric surfaces, in particular surfaces of plastic films, paper webs or plastic fibers are described. First, a plasma is generated through microstructure discharges with a plasma device in at least one plasma region. In addition, the dielectric surface is introduced into the plasma region with a feed mechanism and is temporarily exposed to electrically charged particles generated by the plasma there.
