ABSTRACT:
A corona discharge surface system for treating both conductive and non-conductive materials is disclosed. The system comprises one or more universal electrodes each of which comprises first electrode means configured for corona discharge treatment of non-conductive materials and second electrode means configured for corona discharge treatment of conductive materials. The one or more universal electrodes are arranged on a common support with the combined structure having a pivot point about which the common support is pivotable. In one embodiment, the corona discharge device is used for the treatment of continuous webs of film materials that are moved by one generally cylindrical electrode mounted for rotation about a central axis thereof. The common support is fixed but pivotable so that the first electrode means is configured for corona discharge treatment of non-conductive film materials and the second electrode means is configured for corona discharge treatment of conductive film materials. The common support means has its pivot point disposed parallel to and spaced apart from the central axis of the generally cylindrical electrode. The common support is pivotable for selectably positioning a selected one of the first and second electrodes in spaced corona discharge treatment relation to the generally cylindrical electrode, thereby defining a gap between the generally cylindrical electrode and the selected one of the first and second electrode means for the passage of materials to be treated.
