Abstract

PURPOSE:To prevent deposition of water drops on the inner walls of a hood, by introducing dry air into the hood, in titled discharge treatment carried out while drawing air from the hood surrounding a discharge electrode. CONSTITUTION:In an apparatus for corona discharge treatment comprising a hood 3 surrounding a corona discharge electrode 1 fixed on an electrode holder 2, a pipe 7 for drawing air from the hood and an electrode 1 for treating a plastic film 6, the lower end of the hood 3 is provided with a pupe 4 having holes through which air is injected in the direction of arrows, and dry air is introduced through said holes from a dry air main pipe 5 into the hood. The quantity of said air introduced may be about 1/50 time the volume of air exhausted from the pipe 7.
