Line equipment.

2. Description of the Related Art Conventional winding of toroidal coils is mostly done by hand. In conducting the winding work, a conductor cut to the length required for the winding is manually passed through the window of the ring. ，
It was produced by applying tension to the conductor wire, keeping an appropriate pitch for each turn, and winding it around a magnetic core.

For this reason, in the conventional manual winding method, the conductor wire is wound around the magnetic core every time the conductor wire is wound around the magnetic core.
The insulating layer of the conducting wire has a peeling portion, which causes factors such as coconut palm or wire breakage, which inevitably lowers the reliability of the product, further lowers the productivity, and makes it difficult to provide it at low cost.

Therefore, as one of the above-mentioned drawbacks, there has been proposed a method in which a conductor is electrostatically coated with epoxy resin or a method of wrapping a magnetic core with a two-piece synthetic resin molded product.
Even with these proposals, it is still difficult to contribute to improving productivity, and special equipment is required, which inevitably leads to the drawback of high cost.

Problems to be Solved by the Invention In view of the above drawbacks of the conventional toroidal coil and the winding method thereof, the inventors have completed the present invention as a result of research.

Therefore, an object of the present invention is to automatically guide and wind a conductor wire around a magnetic core without manually winding the winding of the toroidal coil. To prevent the insulation layer from peeling off during winding work, and to form a multi-layered conductor wire with a balanced winding tension.
The present invention is to provide a toroidal coil that can be wound, and further to provide a winding method and a device that can inexpensively produce a toroidal coil by saving the winding work.
