<p>PROBLEM TO BE SOLVED: To provide a method of fixing resin-coated heating wires to a resin cylindrical body without generating working traces on the outer surface of resin-coated heating wires, and rendering its winding condition irregularly. SOLUTION: This is to fix resin-coated heating wires 2 to a resin cylindrical body 1 by use of a core mold 3 and a stationary table 4 provided with a recess 41 having a heating part 411 in substantially parallel with the outer peripheral surface of the core mold 3 at a predetermined distance. The core mole 3 mounted with the resin cylindrical body 1 having the resin-coated heating wires 2 wound therearound is inserted into the recess 41 of the stationary table 4, and heating is carried out from the heating part 411 to thereby perform welding between the resin cylindrical body 1 and the resin-coated heating wires 2.</p> |
