- the conventional winding device winds a wire having a circular cross section, it can be wound without requiring a particularly precise guide.However, a wire such as a square wire is used. When wound with a conventional winding device at high speed, the side of the wire wound around the outer periphery of the pobin and the opposite side of the wire wound adjacent thereto are separated or twisted in the axial direction of the pobin.
- the winding of one layer may be completed without reaching the predetermined number of windings.
- an air layer is formed inside the winding, and the advantage of the coil using the square wire is lost.

In other words, in the case of continuous winding in multiple layers, when the wire rod moves from the lower layer to the upper layer, it is necessary to minimize the gap as much as possible without relying on chance and to achieve accurate winding. This is very important in forming a coil.
