The round electric wire 15 gives a back tension through the dancer roller 2 and, at the same time, stores a certain amount of electric wire in order to absorb a shock at the time of starting and passes it through the eye plate 10. The round electric wires 15 that have passed through the eye plate 10 are arranged and wired in parallel through the arranging portion 3 and fed into the tape fusion portion 4.

FIG. 2 shows an outline of the construction of the embodiment of the tape fusion bonding portion 4. Each of the plurality of round wire 15 fed, inserted into a groove guide 11 ₁ having one of Katsuta 8 of the pair of grooves guide having a groove provided in parallel at predetermined intervals in the vertical direction, the groove guide 11 _1, faces the groove guide 11 ₁ vs fixing tape 14 in the vertical direction indicated by the arrow from above downward by feeder 7 between the channel guide 11 ₂ with the other temperature controller 20 that forms a drooping Supply. When the fixing tape 14 hangs down to a position facing all the round electric wires 15 arranged in parallel in the groove of the groove guide 11 ₁ , the groove guide 11 ₂ is pressed against the groove guide 11 ₁ with the fixing tape 14 sandwiched therebetween. to cut the fixing tape 14 by operating the Katsuta 8 of the groove guide 11 _1. On the other hand the temperature controller 20 to heat the groove guide 11 _2, to form a flat multiple-core wire by fusing the fixing tape 14 to the round electric wires arranged in parallel. After forming the flat multi-core electric wire at the end, it is cooled to a temperature suitable for terminal processing through the cooling unit 5 if necessary, and is fed to the cutting and peeling unit 6. A slide mechanism 12 moves the relative positions of the tape fusion portion 4 and the cutting and peeling portion 6 in accordance with the length of the electric wire, and can be applied to electric wires of various lengths.

For the cutting and peeling unit 6, for example, a general-purpose cutting and peeling machine is applied. By controlling the frequency of the drive motor of the cutting and peeling machine, the timing is measured with the tape fusing section 4, and the tape fusing section 4 and the cutting and peeling section 6 are interlocked with each other by a cutting start signal.

By changing the stroke of the clamp 13 of the cutting and peeling section 6, it is possible to cut the round electric wire where the fixing tape 14 having a predetermined length is fused and fixed to a necessary portion at an arbitrary position, if necessary. The parallel end portions cooled to an appropriate temperature are cut by the fusion tape adjusting cutter 9 provided in the flat multicore electric wire insertion opening of the cutting and peeling unit 6, and the round electric wire coating layer is peeled off.
