Next, two of these winding bobbins are prepared and two insulated wires are twisted together to form a twisted pair wire with a spiral mark. In the manufacturing method of twisted wire pairs, the spiral printing machine is an extremely inefficient manufacturing method due to reasons such as the inability to increase the speed due to its structure. Furthermore, since two take-up bobbins and two delivery bobbins are required, and operations such as moving and replacing the bobbins are required, this method is extremely inefficient in manufacturing.

The thickness of the connecting portion 3 of the insulator 2 such as polyethylene is 0.08 mm.
After being extruded and coated to a thickness of ~0.2 mm, a straight line mark 4 is printed on the lower part of the insulator 2 by a printing machine 10 to form a parallel insulated wire 4. The insulator 2 of the thin connection part 3 of the parallel insulated wire 4 is continuously torn by the splitting plate 12 to become two single wires, which are passed through the die 13 and twisted by the double twist puncher 14 while simultaneously forming a straight line for identification. The mark 4 is turned into a spiral mark 6, formed into a pair of twisted wires 7, and wound onto a winding bobbin 5.
