Abstract
A corona treater includes an active electrode which has one or more insulated electrode elements slidably supported by an insulating track. A contact spring connects each electrode element to a conductive electrode bar embedded in the track, and sheet material to be treated is fed through a treatment zone created between an active discharge surface on each electrode element and a bare metal roller electrode.
