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.

1. 1. An electrode element for a corona treater, which comprises;a case made from a heat resistant electrically insulating material and having a bottom wall which provides a discharge surface and a pair of spaced side walls which connect to the bottom wall and extend upward therefrom;a metal plate disposed between the side walls and against the bottom wall of the case on the side opposite the discharge surface;means for connecting the case to the corona treater; anda contact spring which is disposed between the side walls of the case and having one end in electrical contact with the metal plate and its other end extending upward to make electrical contact with an electrode bar on the corona treater.
