Abstract
Apparatus and method for glow discharge treatment of opposite surfaces of a moving web such as a plastic film or metallic sheet. The web moves in a vacuum housing between two rows of elongated electrodes arranged in a direction transverse to the direction of movement of the web. Coolant flows through an elongated hollow space in each electrode. The electrodes are fitted into a single common socket which is removably attached to the vacuum housing. A shielding member made of metallic material covers only the part of each electrode which is laterally offset to a side of the web. Each shielding member is connected to ground via a conductor and is spaced away from the outer peripheral surface of each electrode by a gap which is sufficiently small to prevent discharging of electricity from occurring in the gap when the web is subjected to glow discharging treatment.
