It is composed of a colored band 3 made of extruded material. This colored banded sheath cable 4 is extruded using a crosshead shown in FIG. This crosshead is composed of a mandrel 6 attached to a crosshead body 5 and a mouthpiece 8 tightened by a die nut 7, and further includes an auxiliary extruder nozzle 10 for supplying a color strip 9 of colored projection material. is provided. The sheath material 11 pushed out by the main screw is the mandrel 6
and the cable core 1 through the passage between the cable core 1 and the base 8
extruded as a sheath around the On the other hand, the colored band material 9 of the colored projection material is extruded by the screw of the auxiliary extruder, passes through the auxiliary extruder nozzle 10, reaches the mouthpiece 8, and is extruded simultaneously with the sheath material 11.

帯３がずれることがある。[Problems to be Solved by the Invention] The sheathed cable with colored band protrusions has significantly improved sheath Meg characteristics compared to the colored banded sheath cable, but when the above-mentioned prior art cap with protrusions is used, the cable shown in Fig. 8a As shown in FIG. 1, the projection material is pushed up by the pressure of the sheath material, and the color band 3 enters only a part of the projection part 15. For this reason, when viewed from the side, it looks like a normal cable with no color band and protrusions.
Furthermore, in this manufacturing method, it is necessary to align the auxiliary extruder nozzle and the protrusion groove of the protrusion cap, and if they are not aligned, the color band 3 may shift as shown in Figure 8b. .

ケーブルの製造が可能になる。[Function] In the present invention, the protrusion material that passes through the protrusion material supply hole from the auxiliary extruder nozzle and passes through the protrusion groove of the protrusion cap is extruded in a parallel portion where it is hardly subjected to the pressure of the sheath material. It is in. Therefore, the entire protrusion can be formed of the protrusion material without having to align the protrusion as in the conventional case, and the workability of cable manufacturing is improved. Furthermore, by using a colored protrusion material, it becomes possible to easily manufacture a sheathed cable with colored protrusions provided with a colored band.
