Field of the Invention The present invention relates to an improvement of a cable sheathing apparatus, and in particular, to the development and application of a cable sheath assisted incision sheath necessary for improvement of a cable sheathing apparatus, and improving the performance of an existing cable sheathing apparatus.

Generally, a cable consists of an inner metal wire or optical fiber for carrying electricity or light, and a covering which surrounds and protects it. An example of such a cable is shown in Fig. Referring to FIG. 1, the cable 10 includes a metal wire or an inner wire 14 made of metal surrounding the wire 12, and a synthetic resin such as PE surrounding the inner wire 14 (16). ≪ / RTI > The cover 16 is strongly pressed against the inner film 14 so as not to move for preventing moisture and moisture, preventing electric noise due to external influences and the like. These cables 10 are of various diameters depending on their use.

As the technology of electric and communication fields develops rapidly, the amount of cables 10 to be replaced and discarded is increasing day by day, and environmental pollution is also a problem. The cable 10 is peeled from the cloth 16 so that it can be separated and recycled for each material. Since the recycling of the cloth 16 made of a synthetic resin such as PE among the materials of the cable 10 is economical, a lot of devices for removing the covering of the cable 10 have been developed.

In the announcement number room 1994-0002342 (unloading of super high voltage cable, Apr. 13, 1994) and Publication No. 2000-0027193 (unloading device of optical cable, published on May 15, 2000) Discloses a method in which a cloth is cut with a blade so that the cut cloth is separated into left and right sides.

Japanese Patent Laid-Open Publication No. Hei 9-55135 (Apparatus and Method for Separating Core Wire and Cladding Material of Wire, published Feb. 25, 1997) discloses a wire feeding device, a preheating device for preheating a supplied wire, Discloses a cloth separating apparatus and a method comprising an apparatus.
