実に多数の凹凸状の粗面部を形成できるものである。Since the present invention is constructed as described above, when it is used as a cable erection coil, it is much easier to install than a conventional cable hanger erection work, Since the twist is formed so as to rotate along the entire surface, the wind noise caused by rain and wind can be reduced, and the rain flow can quickly descend to reduce the weight. In addition, since a protective film layer made of a water-repellent synthetic resin is superposed and laminated on the outer periphery of the coating layer, the outer periphery of the coil body is toughened, and the effect of dissipating moisture and the snow and the like on the outer periphery of the coil body are obtained. This has the effect of solving the drawbacks such as freezing in the winter season due to the adhesion of water droplets and the weight of the coil body increasing and sagging. Further, the constituent material of the water-repellent synthetic resin of the protective film layer has a low melt viscosity and uses a mixed synthetic resin of powder and particles of a high fluidity additive, and after extrusion molding, is applied to the surface of the protective film layer. Since the uneven surface is formed, the frictional resistance on the surface of the protective film layer is further reduced, so that the effect of reducing wind noise and removing rain and snow by improving water repellency is more excellent. According to this method, a coating layer is provided on the outer periphery of a metal wire in a die, and a protective film of a synthetic resin having a small frictional resistance is provided with water repellency on the outer periphery of the coating layer. The layers can be easily and simultaneously polymerized and laminated, and the entire coil body can be easily twisted with a sizing die during softening. Furthermore, according to the material of the protective film layer, which has a low melt viscosity and a high fluidity additive powder and a mixed synthetic resin of particles, the surface of the protective film layer of the coil body surely has a large number of uneven surface portions. It can be formed.

のである。Since the present invention is constructed as described above, when it is used as a cable erection coil, it is much easier to install than a conventional cable hanger erection work, Since the twist is formed so as to rotate along the entire surface, the wind noise caused by rain and wind can be reduced, and the rain flow can quickly descend to reduce the weight. In addition, since a protective film layer made of a water-repellent synthetic resin is superposed and laminated on the outer periphery of the coating layer, the outer periphery of the coil body is toughened, and the effect of dissipating moisture, and the rain and snow on the outer periphery of the coil body, This has the effect of solving the drawbacks such as freezing in the winter season due to the adhesion of water droplets and the weight of the coil body increasing and sagging. Further, the constituent material of the water-repellent synthetic resin of the protective film layer is dissolved from the base material.
Since the melt viscosity is large and the powder of the additive having low fluidity and a mixed synthetic resin of particles are used, and after extrusion molding, a rough surface portion having an uneven shape is formed on the surface of the protective film layer, the Since the frictional resistance of the surface is further reduced, the effect of removing rain and snow by reducing wind noise and improving water repellency is more excellent. Further, according to this manufacturing method, as a method of manufacturing a cable erection coil, a coating layer is formed on the outer periphery of a metal wire in a die, and a protective film made of a synthetic resin having a low frictional resistance and having water repellency on the outer periphery of the coating layer. The layers can be easily and simultaneously polymerized and laminated, and the entire coil body can be easily twisted with a sizing die during softening. Furthermore, according to the material of the protective film layer, which has a low melt viscosity and a high flowability additive powder and a mixed resin of particles, the surface of the protective film layer of the coil main body is surely provided with a large number of uneven surface portions. It can be formed.
