You can also do that. In addition, if an insulation defect is discovered, it is possible to immediately stop the rotation of the core 15 by an electric signal from the power supply circuit of the metal roller 16, or conversely, the winding is completed and the core 15 is stopped. When the rotation stops, it is also possible to automatically stop supplying the electric image to the metal roller 16.
