PURPOSE:To prevent torsion between a supporting wire section and a table core section of a cable with a supporting wire (SS) by making adjustable the distance between an inlet to a cooling water tank of the cable and to adjusting rollers. CONSTITUTION:High density polyethylene extruded from an extrusion molding machine A onto an introduced table core (b) and a supporting wire (a) is extrusion molded in a section of twin-round form. A cover (c) of high-density polyethylene extrusion molded in the twin-round form section is not solidified instantly but remains paste-like, and cooled by the cooling water in a cooling water tank B and solidified, and the form of the same is fixed. An accordion-shaped auxiliary water tank B' is continuously connected onto the inlet side of the water tank B, and the distance from an inlet 2 of the water tank B' to adjusting rollers D can be adjusted. The adjustment of said distance is for the purpose of pinchingly pressing the extrusion molded cover (c) by adjusting rollers D immediately before the cover is solidified. |
