Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a stranded wire in which a plurality of strands are stranded 4 degrees and an apparatus for producing a stranded wire.

[0002]

2. Description of the Related Art Conventionally, when a plurality of strands are twisted 4 times, a twisted wire manufacturing apparatus capable of twisting 2 times is used first.
After twisting twice, after winding the twisted wire twice from the drum wound up on another drum, it is passed through the twisted wire manufacturing device again to form a twisted wire of 4 degrees, Alternatively, it is twisted 4 times by using a twisted wire manufacturing apparatus configured so that it can be reciprocated.

[0003]

The conventional double threading method has a drawback in that the rewinding for double threading and the movement of the winding drum are troublesome and the work efficiency is poor. Further, in the latter case of the reciprocating running line method, the work of the twisted wire manufacturing apparatus must be performed twice by twisting and then four times, and the workability is poor. There was a flaw.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
It is an object of the present invention to provide a stranded wire manufacturing method and a stranded wire manufacturing apparatus capable of simultaneously performing a two-twisting operation and a four-twisting operation.

[0005]

In order to achieve the above-mentioned object, the present invention provides a break unit capable of applying a predetermined tension to a plurality of wires from a plurality of supply wire bobbins, an eye plate,
First winding a twisted wire twice through a die and a first flyer rotating at both ends with rotating sheaves and then wound around a first or second winding drum provided on a floating frame.
And the twisted wire twice twisted around the first or second winding drum in the first twisted wire step is shielded at both ends during the first twisted wire step. The second twisted wire step of passing the second flyer through which the twisted wire is twisted 4 times and winding the twisted wire on the winding drum constitutes the method for manufacturing the twisted wire.

[0006]

The function of manufacturing the stranded wire configured as described above is as follows:
The first twisted wire step of twisting twice and the second twisted wire step of twisting four times can be performed at the same time.
