Flat cables for high-speed computers are required to have the same electrical length for each insulated core wire, but the insulated core wires that make up the flat cable have variations in electrical characteristics such as delay time. If cut to the same length, there will be a difference in electrical length. In order to solve this problem, a flat cable using different lengths of insulating core wires and arranging them in parallel has been studied.

However, in the above-described conventional flat cable manufacturing apparatus, since it is an apparatus for continuously manufacturing a long flat cable having a fused portion and a non-fused portion, a plurality of insulating core wires having different lengths are provided. It is not possible to manufacture flat cables of a predetermined length by arranging them in parallel.

Further, in recent years, flat cables have been diversified, and a cable having a branch portion at one end has been required.

Is placed. The pin 15 is attached to the main body of the flat cable manufacturing apparatus.

An alignment carrier 5 provided so that the end portions of a plurality of insulating core wires 1 having different lengths are fixed and the insulating core wires 1 are arranged in parallel is placed on the slide base 12 and the balls are arranged. It is moved to the left by the drive of the motor 14 via the screw 13, and is moved to a position between the pair of fusion-bonding heater chips 10 arranged opposite to each other and stopped. Next, since a plurality of insulating core wires 1 arranged in parallel with the stopped aligned carrier 5 are pressure-bonded from above and below to intermittently provide the fusion-bonded portions 2, the pair of fusion-bonded heater chips 10 are connected to the air cylinders 11. And the insulation core wires 1 are pressed from above and below. In order to obtain the accuracy of the wire pitch between the insulating core wires 1, this crimping is performed by arranging a plurality of insulating core wires 1 in parallel in the groove 8 of the total width guide plate 7 provided in the alignment carrier 5 as shown in FIG. It is carried out at a position (A) where it is arranged and is in contact with the total width guide plate 7. Also,
