Abstract

PURPOSE: To provide a needle electrode having a uniform insulation coating in using a marketable circular cross sectioned copper wire by a method wherein a circular cross sectioned covered copper wire is rolled flatly with a rolling mill to wind up as giving a tension thereof.
CONSTITUTION: A circular cross sectioned copper wire insulated preliminarily is wound around a strand bobbin 6 to feed into a roller 8 through a idle pulley 7 in pulling out the copper wire from the bobbin 6. The rollers 8 are respectively rotating as shown by an arrow direction. The copper wire 9 forming the insulation coating 9a is rolled closed to a flat rectangular shape by passing through the rollers 8. The rolled covered copper wire (electrode wire) is wound around the winding jig 14 through the idle pulleys 11, 12, 13. A weight 27 is connected with the idle pulley 12 to give a fixed tension on the electrode wire after rolled.
