[0002]

2. Description of the Related Art For wire harnesses installed in automobiles,
As shown in FIG. 7, a large number of electric wires 2 are bound with a tape 3 to form a circular cross section. When there are many electric wires 2 to be bound, the wire harness 1 has a large-area circular shape. In some cases, this type of wire harness 1 must be routed between the vehicle body panel 4 and the trim 5 as shown in a gap 6 having a narrower spacing than the diameter of the wire harness 1. In such a case, in order to pass the wire harness 1 through the narrow gap 6, it is necessary to provide the wire harness 1 with a flat flat portion having a thickness smaller than that of the gap 6.

Conventionally, when the flat portion is provided on the wire harness 1, as shown in FIG. 8 (A), first, the tape is provided on a portion other than the section F which is the flat portion 8 of the wire group 7 of the wire harness 1. 3 is wrapped around to bundle the electric wire group 7, and then the operator manually spreads the electric wire group 7 in the section F in which the tape 3 is not wound as shown in FIG. Arrange it flat. In this state,
Adhesive films and the like are attached to both sides of the section F of the electric wire bundle 7 to fix the electric wires 2 arranged in parallel.

In order to install the wire harness in the gap 6, there is a method of using a flat cable 11 in which a plurality of electric wires 12 are integrally connected in parallel as shown in FIGS. When using the flat cable 11, first,
As shown in FIG. 9 (A), the flat cable 11 is cut to fit the longest circuit, and the whole is cut. Then, as shown in FIG. The part is cut off.

In the prior art shown in FIGS. 8 (A) and 8 (B), it is necessary for an operator to manually spread the once bundled wire group 7 and arrange the wires 2 in parallel. There is a problem in that this arrangement work takes time and the manufacturing cost of the wire harness increases accordingly. Moreover, since the electric wires 2 are arranged manually, the electric wires 2 may overlap in the flat portion 8,
There is also a problem that the gap between the electric wires 2 is not uniform.

Further, in the prior art shown in FIGS. 9A and 9B,
When cutting the flat cable 11 as shown in FIG. 9 (A),
Since the flat cable 11 is cut in accordance with the longest circuit, the portion of the dotted frame 14 shown in FIG. 9B to be cut off is wasted, and there is a problem that the manufacturing cost of the wire harness increases accordingly. Further, since the electric wires 12 of the flat cable 11 are integrally connected, when the electric wires 12 are connected to the connector, a cut is made at the tip of the flat cable 11 so that the electric wires 12 are separated from each other. This requires work, and also from this point, there is a problem that the manufacturing process of the wire harness is complicated and the cost is increased.

The present invention has been made in view of the above problems, and enables a flat portion to be formed in a wire harness in accordance with the work of laying the electric wires of the wire harness, and simplifies the manufacturing process of the wire harness.
