ABSTRACT:
Corona discharge treatment apparatus for treating or coating a surface of a conductive substrate includes a high voltage radio frequency power supply and a cable having a number of flexible conductors and other components. The cable has a first end connected to the power supply and a second end wherein the other cable components have been removed and the conductors extend from the remainder of the cable. The free ends of the conductors at the second end are disposed in a general non-parallel arrangement and the free end of each conductor is held in a separate insulator which extends beyond the free end it holds. Each free end is movable independently of the other free ends. The conductive substrate is held beneath the cable second end so that the upper surface is engaged by the insulators. The conductive substrate is grounded, and relative movement is effected between the second cable end and the conductive substrate while a gas mixture is introduced into the area of engagement between the upper surface and insulators.
