Abstract

PURPOSE:To efficiently manufacture a flat electric wire with conductor exposed portion reinforcement. CONSTITUTION:A first and a second heating roll 16, 17 are used in order to reinforce conductor exposed portions of a flat electric wire 6A with a conductor exposed portion by the use of a reinforcing tape 9 so as to manufacture a flat electric wire 6B with conductor exposed portion reinforcement. The flat electric wire 6A with a conductor exposed portion passes in an S-shape in contact with the first and second heating rolls 16, 17 with application of heat, while the reinforcing tape 9 is temporarily attached to the conductor exposed portion of the flat electric wire 6A with the conductor exposed portion on the outer periphery of the first heating roll 16 by a reinforcing tape temporarily attaching machine. When the reinforcing tape 9 passes between the first and second heating rolls 16, 17, the reinforcing tape 9 is pressurized by the first and second heating rolls 16, 17 so as to be actually fixed to the conductor exposed portion.

2. Description of the Related Art Recently, flat electric wires called tape electric wires, card electric wires and the like have been used as internal wiring for telephones, facsimiles, electronic copying machines and the like.

Conventionally, the production of such a flat electric wire is
It went as follows. That is, as shown in FIG. 10, before passing the insulating tape 1 such as both plastic tapes between the pressure rollers 2, the insulating tape 1 is punched by the punching machine 3 at predetermined intervals in the longitudinal direction to form the window 4. Then, the insulating tapes 1 are supplied between the pressure-bonding rollers 2, and a plurality of conductors 5 arranged side by side at a predetermined pitch in the width direction are supplied between the insulating tapes 1 between the pressure-bonding rollers 2. ,
By sandwiching the conductors 5 from both sides with the insulating tape 1 between the pressure-bonding rollers 2 and integrating them, a tape-shaped flat electric wire 6A with an exposed conductor portion is manufactured. At the time of pressure bonding by the pressure roller 2, the insulating tape 1 is bonded or fused to each conductor 5 and the insulating tape 1 on the opposite side to be integrated. In this case, the two insulating tapes 1 integrated together form a flat insulator 7. In such a flat electric wire 6A with an exposed conductor portion,
Each conductor 5 is exposed at each window 4 to form a conductor exposed portion 8.

Flat electric wire 6A with such an exposed conductor portion

It becomes B. To attach the reinforcing tape 9 to the exposed conductor portion 8, for example, a fusion layer or an adhesive layer having a low melting point is provided in advance on one surface of the reinforcing tape 9 and then the reinforcing tape 9 is attached by heating.

The attachment of the reinforcing tape 9 by the first and second heating plates 10 and 11 is performed by temporarily stopping the feeding of the flat electric wire 6A with the exposed conductor portion at that time, or the first and second heating plates 10 and 11.
The heating plates 10 and 11 are moved at the same speed as the feeding speed of the flat electric wire 6A with the exposed conductor portion. When the reinforcing tape 9 is attached by moving the first and second heating plates 10 and 11, when the attachment is completed, the first and second heating plates 10 and 11 are
11 is returned to the original position.

The thus-obtained conductor-reinforced flat wire with reinforcement 6B is cut in the next step along the cutting line 12 shown in FIG. 12 to remove both ears of the conductor-reinforced flat wire with reinforcement 6. Next, at the center of each exposed conductor portion 8, the cutting line 13

When the reinforcing tape 9 is attached by moving the first and second heating plates 10 and 11, it takes time for the first and second heating plates 10 and 11 to reciprocate. When the feeding speed of the flat electric wire with conductor exposed portion 6A is high and the distance between the front and rear conductor exposed portions 3 is short, there is a problem that the first and second heating plates 10 and 11 cannot follow. An object of the present invention is to provide a method and a device for cutting a flat wire with a conductor-exposed portion reinforcement, which enables efficient production of a flat wire with a conductor-exposed portion reinforcement.
