る。[Example] The present invention will be described below based on the illustrated example. FIG. 1 shows an embodiment of the invention. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, a guide pipe 10 having an inner diameter 0 to 50 microns larger than the theoretical tape-wrapped diameter, which is the sum of the core diameter and the metal tape thickness, was used. By doing this, the metal tape 3a is pressed against the core 6 on the inner surface of the guide pipe 10, and the winding is formed, so that it comes into close contact with the insulator of the core 6, and the core 6
It is possible to obtain a metal tape wrapping method that makes it possible to significantly improve the adhesion between the insulator and the metal tape 3a.

The core 6 together with the guide pipe 10 is rotated at a constant speed around the core while applying an appropriate tension to a, and at the same time the cable 8 wrapped with the metal tape 3a (cable after wrapping with the metal tape) is rotated at a constant speed. By pulling it out from the guide pipe 10, the metal tape 3a can be wrapped around the core 6 at a constant pitch with strong adhesion.

ある。The reason why the inner diameter of the guide pipe in this example was limited to 0 to 50 microns larger than the theoretical metal tape winding diameter is that immediately after the metal tape is wound, the metal tape is rotated while pressing it against the core on the inner surface of the guide pipe. This is to form the metal tape so that the metal tape and the core are in close contact with each other.

Since we used a guide pipe with a micron-large inner diameter, the metal tape is pressed against the core on the inner surface of the guide pipe, and the winding is formed, so that it is tightly bonded with the core's insulator, and It is possible to obtain a metal tape wrapping method that makes it possible to significantly improve the adhesion between an insulator and a metal tape.
