通過させることは、容易ではなかつた。Prior Art It is widely known that corona discharge treatment is applied to the surface of thermoplastic resins for the purpose of improving the surface properties of thermoplastic resins such as polyolefins such as polyethylene and polypropylene and increasing their adhesion with paints, etc. There is. In addition, when attempting to improve the surface properties uniformly and sufficiently by such corona discharge treatment, the surface of the object to be treated should be passed between the electrodes as close as possible to the electrodes and at a uniform distance. It is also known that it is necessary to do this, and various ideas have been made and proposed so far. However, it is not so difficult to meet these requirements when the object to be processed is a flat, web-like thermoplastic resin, but it is not so difficult to meet these requirements when the object to be processed is a flat, web-like thermoplastic resin. In the case of molded bodies with surfaces, it is not easy to pass the surface to be treated between the electrodes sufficiently close to the electrodes and at a uniform distance.

た。Problems to be Solved by the Invention It is true that according to this device, by moving and rotating the upper electrode and the lower electrode according to the surface shape of the molded object, it is possible to uniformly apply corona discharge treatment to the surface of the molded object. Although it is possible to some extent, it is impossible to move the upper and lower electrodes so that the distance between them is completely uniform, and also to always match the shape of the discharge device to the surface shape of the object to be treated. Therefore, with this apparatus, it was not possible to obtain sufficiently satisfactory uniformity of processing, and there was also the problem that the apparatus and operation were extremely complicated.
