Therefore, the feeding tension of the tape body 1 from the tape pad 102 by the torque control of the drive motor 106 is set at zero tension, and even if the winding amount of the tape pad 102 changes, it is fed out with almost zero tension. There is no change in shape such as elongation or twist. It should be noted that the actual tension wound around the wire 10 is about 0.5 N, due to the galling of the tape guide rolls 122, 123, and 124.
- the tape supply unit controls the rotational torque of the first drive source so that the tape supply from the tape pad 102 is always performed with an appropriate feeding tension and can be rotated coaxially with the tape supply unit.
- the attached tape collar is unstable because the tape is wound by rotating the second drive source fixed to the end of the tape collar, but the tape winding tension is kept constant by the tension control roll of the tape collar. Therefore, the PTFE porous tape body having a porosity of 3 ⁇ 40% or more and a thickness of 0.09 mm can be wound with high accuracy by the tape-insulated core manufacturing apparatus of the present invention.
- the degree of adhesion of the tape body to the wire is made constant, and the wire can be made stable by winding the tape. Capable of providing an efficient tape-wrapped insulation core manufacturing apparatus.
