Abstract

986,680. Spark gaps. NATIONAL DISTILLERS & CHEMICAL CORPORATION. Jan. 3, 1962 [Jan. 12, 1961], No. 218/62. Heading H1X. Apparatus for the corona discharge treatment of a polyethylene or polypropylene film 14 comprises an electrode 11 for generating a corona discharge supplied with high-frequency current by a generator 10, an earthed electrode 13 and a dielectric member 15 interposed between the electrodes, the electrode 11 comprising a plurality of knife edges 12 positioned generally parallel to the direction of travel of the film being treated and connected together to form an electrically continuous electrode which extends transversely across the width of the film. The knife edges may be formed by a helical thread on a cylindrical, semi cylindrical or square rod 11 thus repetitively extending portions of itself into corona discharge spatial relationship with respect to the other electrode 13, or may be rasp or file shaped. Several such electrodes may be arranged successively along the direction of travel of the film, all parallel to each other. A specific example is given indicating the circuitry required for the apparatus.
