Abstract

The insulating members, almost circular or oval in cross section with an outer diameter virtually equal to the thickness of the rectangular conductor, are arranged in such a manner as to be alternated with the rectangular conductors and are held between the two insulating tapes from both the upper and lower sides, with the adhesive layer filling the space between the two facing tapes. The insulating tapes with adhesive layers on the opposing inner sides are pressed against the conductors and the insulating members by the press-forming rollers to form a tape wire.

Claims

1. A tape wire comprising:

a plurality of parallelly arranged conductors;

insulating tapes holding the conductors therebetween from both the upper and lower sides;

an adhesive layer interposed between the facing insulating tapes; and

insulating members almost circular or oval in cross section, the insulating members each having the outer diameter almost equal to the thickness of the conductor, the insulating members being arranged in such a way as to be alternated with the conductors.

2. A tape wire as claimed in claim 1, wherein the conductors are rectangular in cross section.

3. A tape wire as claimed in claim 1, wherein the conductors are circular in cross section.

4. A tape wire as claimed in claim 1, wherein the insulating members each comprises a plurality of insulating members put close together in a row.

5. A tape wire as claimed in claim 1, wherein the insulating members each comprises a plastic or synthetic fiber string or a band of fine synthetic fibers.

6. A method of manufacturing a tape wire comprising the steps of:

feeding to press-forming rollers a plurality of parallelly arranged conductors, insulating members and two insulating tapes in such a way that the insulating members are alternated with the conductors, the insulating members being almost circular or oval in cross section and having an outer diameter almost equal to the thickness of the conductors;

holding the conductors and the insulating members between the two insulating tapes from both sides thereof by the press-forming rollers; and

pressing the two insulating tapes against the conductors and the insulating members by the press-forming rollers, with an adhesive layer interposed between the two opposing insulating tapes.
