This hanging type discharge electrode 3 includes an electrically conductive support shaft 4 extending downward from a support frame (not shown), and an electrically conductive electrode member mounting member 5 attached to the lower end of this support shaft 4 and provided horizontally. It is equipped with
A large number of discharge electrode members 1 are attached to the bottom surface of this electrode member attachment member 5 so as to hang down. The discharge electrode members 1 are arranged vertically and horizontally at regular intervals when viewed from the bottom.

は下表にみる通りである。The same length is used for each length. As shown in FIG. 3, the test situation for this hanging type discharge electrode 4 was such that a flat plate-shaped object 7 made of PP material was placed on the base electrode 6. A vertically oriented electrode member attachment member 5 is installed, and discharge electrode members 1 made of, for example, 200 twisted single fibers of 12 μΦ are suspended from the electrode member attachment member 5 at equal intervals. A high frequency type fX8 is connected between the base electrode 6 and the electrode member mounting member 5 to apply a high voltage, and the object to be processed 7 and the discharge electrode member 1
can be moved relatively by moving either one of them. Thereby, the surface of the object to be treated 7 is subjected to the discharge treatment, and the desired improvement in the peel strength and the like of the surface can be obtained. The results using the discharge electrode member 1 are shown in the table below.

電極部材用として採用に不向きなところがある。In this way, the discharge electrode member is made of a large number of single fibers with extremely small diameters, so it is neither weak nor too strong, making it a somewhat sturdy electrode member that can be easily touched by a light touch. It comes into contact with the surface of the object to be treated, and since it is made up of a large number of single fibers, stable and reliable contact can be achieved. As a result, the discharge effect is stable and reliable, and no damage is caused to the electrode member or the object to be treated. However, although a similar discharge effect can be obtained by simply bundling a large number of supporting fibers without twisting them together, this method is unsuitable for use in electrode materials because it tends to cause fuzzing.

In this case, as shown in Fig. 5, which shows an enlarged view of the main part of the implanted part, the rotor 9 has a horizontal cross section with the opening side of the groove widened. A spring-shaped first rotating member 10 and a second rotating member 11 having a similar structure are formed so that they are screwed into each other and fit between the spirals. 2 rotating member 1
0.11 are fitted together by spring force so that they are adjacent to each other, and between the adjacent parts, a coil spring-shaped electrode member mounting member 5 having a J-shaped cross section is similarly screwed and fitted. It is designed to be crowded. The discharge electrode member 1 is
Their bases are attached by caulking into the U-shaped groove of the electrode member attachment member 5, and a large number of them are arranged along the circumferential direction. The discharge electrode member 1 is set to be inclined by an angle θ in one direction of the axial center of the rotating body 9 with respect to a vertical reference line V drawn by a broken line in the outer diameter direction.

It is advantageous to do so. This θ can be set to be large or small by changing the rising angle α of the flanges 10a and lla of the rotating member 10.11. Various plastic (resin) solutions having excellent heat resistance, wear resistance, and flexibility can be used for the plastic (resin) coating of the discharge electrode member. For example, examples include acrylic resin, vinyl resin, polyester resin, epoxy resin, polyamide resin, polyamide resin, melamine resin, fluororesin, silicone resin, and the like. Although the discharge electrode member 1 is set at the angle θ, in a natural state, it may assume an inflexible posture as indicated by the dashed line in FIG.

Alternatively, it can also be vibrated horizontally (rotationally). It goes without saying that the discharge electrode member is not limited to stainless steel.
