Abstract
Disclosed is a method for cooling a coated wire including: preparing a water storage tank disposed between an extruder for coating a core wire with an insulating material and for feeding the coated wire forwardly, and a winder for winding the coated wire; and passing the coated wire before being wound through still water in the water storage tank thereby rapidly cooling the coated wire, the improvement comprising: preparing trough members disposed between the water storage tank and the extruder along the advance direction of the coated wire in such a manner as to cover the coated wire from the underside; and cooling the coated wire by water which is discharged to the trough members and is made to flow therein and thereafter passing the coated wire through the water storage tank. Using the above method, even in manufacture of an insulated wire having a coated outside diameter of 1 mm or less, it is possible to suppress the surface roughness of the coated wire in the degree of at least 1 .mu.m.
