By the way, the winding tool described in Patent Documents 1 and 2 applies a back tension to the insulating tape while energizing the friction roller via an oscillating arm by an energizing spring. Therefore, the strength of the back tension inevitably differs depending on the wound outer diameter of the insulating tape. For this reason, the wound outer diameter of the attached insulating tape is large, that is, the back tension is weak in the initial stage of the winding operation, but the winding outer diameter gradually decreases with the progress of the winding operation. In conjunction with the insulation tape, the back tension becomes very strong,
Winding work must always be performed with non-uniform back tension, and as a result, winding is insufficient and electrical inconvenience is likely to occur in terms of insulation and waterproofness. . In addition, since the viscosity and hardness of the insulation tape vary due to changes in the outside air temperature, etc., the back tension must always be adjusted properly, making the adjustment work extremely cumbersome and cumbersome.

Insulation tape characterized by guiding in the winding direction The winding tool is intended to be the subject matter of the present invention.
