Inlet of each of the twisting die 2 for twisting 11 wires to make a 7-core twisted wire, and the twisting die 3 for twisting 12 strands on a 7-core twisted wire to make an electric wire. In filling, tape-shaped watertight materials 4 and 5'r are respectively supplied to the assembled strands, and a gas burner is placed on the λ mouth side of each die to heat it, melting the tape-shaped watertight material and forming the strands. I try to let it seep in between.

作業線速を大きくすることは困難であった。In the above conventional method, the watertight material is processed into a tape shape, which may result in high costs.Also, when processing the watertight material into a tape shape, it is difficult to make the tape thinner than a certain limit.・Electric wires The thickness may be too large for the filling 'ItK, which may result in loss of watertight material. In addition, the excess p watertight material may adhere to the surface of the electric wire and cause unevenness on the surface. Furthermore, since the wire is heated by a gas burner at the inlet of the twisting die, there is a risk that the hard wire will be softened and its tensile strength will deteriorate. However, there is a possibility that the strands may turn red due to heating.Furthermore, there is a drawback that it is difficult for the honey material to enter the gaps between the strands. In addition, the watertight material is supplied in the form of a tape and is permeated by heating.
It was difficult to increase the working linear speed.

A second wire twisting machine 13 is provided which twists 12 strands of wire onto the seven twists 12 formed by the wire twisting machine 10 to form an electric wire. A twisting opening (/i' is also provided with the circular pressure die 14 shown in FIG. 3B. Furthermore, an extruder I5 is installed above the line. The nozzle of the extruder 15) 6 is the first twisting machine] The nozzle 16 has a branch 16a on the artificial side and a branch 16b on the outlet side of a circular pressure die 1 of 0. Also, a heater 17 is attached to the nozzle 16.

二ることはない、。As described above, in the present invention, the water honey material is supplied in a molten state and is not processed and supplied into a tape shape as in the past, so that the cost of producing a tape can be avoided. Moreover, since the extruder can be used to supply a suitable amount of watertight material, there is no loss of watertight material. First, the adhesion resistance of the honey material creates unevenness on the wire surface]

In addition, since the water jungle material is supplied in a molten state, it is easy to crowd between the strands of wire, and the working wire speed can be increased.
