に水没通過させて外被Ｃを冷却固化する。In order to extrude the jacket of this SS cable P, as shown in Fig.
are supplied in parallel, and after integrally extruding the jacket C on both a and b, the cable P is submerged and passed through a cooling water tank B, and the jacket C is cooled and solidified.
ところで、このＳＳケーブル製造時、第５図に示すよう

被Ｃの樹脂が充分固まる（形状が固定する）までに前記
撚戻りの力が働くと、ねじれた状態で形状が固まってし
まうためである。By the way, when manufacturing this SS cable, cables are often produced that are twisted between the support wire portion and the cable core portion, as shown in FIG. This is due to the untwisting of the galvanized steel wires that make up the support wire a and the untwisting of the cable core b.The outer sheath C is extruded and enters the cooling water tank B, and the resin of the outer sheath C hardens sufficiently. This is because if the untwisting force acts before the shape is fixed, the shape will be fixed in the twisted state.
上記のことから、従来から、第１図に示すように、押出
成形されたＳＳケーブルＰを冷却水槽Ｂに導き、該水槽
Ｂ内で矯正ローラＤにより挾持するようにしているが、
その効果が表われない場合、あるいは、外被Ｃ表面に矯
正ローラＤによるヘタリが生ずる場合などがある。In view of the above, conventionally, as shown in FIG. 1, the extruded SS cable P is led to a cooling water tank B and is held between straightening rollers D in the water tank B.
There are cases where the effect is not apparent, or where the surface of the outer cover C is sagged due to the correction roller D.

持されるとヘタリが生ずるからである。This means that depending on the size of the cable, the jacket C is in the water tank B.
If the resin in the outer sheath C hardens before it is compressed by the straightening roller D, the effect will not be apparent, and if the resin in the outer sheath C is soft, This is because if it is pinched, it will become stiff.
