The core 1 is moved in the direction of the arrow 15, the projecting rods 2, 5, 8 are projected almost in parallel with the core 1 when necessary, and the force is composed of the coil wires. Hook 4 and wind coil wire 4 around core 1 and protruding rods 2, 5, and 8 to form loops 3a, 3b, 6a, 6b, 9a, and 9b. Then, the tap 7 is formed by twisting the loops 3a, 3b, 6a, 6b, 9a, 9b by another means of another process, as shown in FIG. Manufacture coil 6 with tap.

In the apparatus of the present invention, as shown in FIGS. 8 and 9, the coil wire supply section is a flyer 12 having a hole 12 a through which the coil wire 4 is supplied and passes, or the coil wire 4. Is wound and accumulated and is not shown in the drawing.

The above-described method and apparatus of the present invention are appropriately driven and controlled by driving means controlled by a computer.
