Patent ID: 7326298

Claim:
A wire insulating line, comprising: an extruder for coating resin to a core wire; a cooling device for cooling down the coated wire, which is extruded from said extruder and allowed to travel, in cooling water in a reservoir tank; a coated wire haul-off machine that hauls the coated wire from said cooling device to allow it to travel and cools down the coated wire by cooling water; and a take-up machine for taking up the coated wire from said coated wire haul-off machine, wherein said coated wire haul-off machine comprises: front and rear capstans for winding the coated wire, which comes out of said reservoir tank and on the way to said take-up machine after the wire is resin-coated and led into said reservoir tank, by allowing the wire to reciprocate back and forth for several times; and a water film flow forming groove body to form water film flow for cooling, which is arranged between said front and rear capstans and extends along a lower coated wire traveling path between said front and rear capstans such that the front and rear capstans are not in the water film flow, wherein said coated wire haul-off machine is constituted that said coated wire is allowed to travel in said water film flow between said front and rear capstans.
