DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, when a plurality of strands are twisted four times, a twisted wire manufacturing apparatus capable of twisting twice is used first.
After twisting twice, winding it on another drum from the drum on which the twice twisted wire was wound, and then passing it through a twisted wire manufacturing device again to form a twice twisted wire, Alternatively, the wire is twisted four times using a stranded wire manufacturing apparatus configured to be capable of reciprocating running.

[0003]

The conventional double threading method has the disadvantage that rewinding for double threading and the movement of the winding drum are troublesome, resulting in poor work efficiency. Further, in the case of the latter reciprocating running method, the operation of the stranded wire manufacturing apparatus must be performed by repeating twice the twisting operation after performing the twisting operation twice, and the workability is poor. There were drawbacks.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a method for manufacturing a stranded wire and an apparatus for manufacturing a stranded wire, which can simultaneously perform a twice twisting operation and a fourth twisting operation.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a brake unit which can apply a predetermined tension to a plurality of wires from a plurality of supply wire bobbins;
A first winding device that winds a stranded wire that has been twisted twice on a first or second winding drum provided on a floating frame through a rotating first flyer having a die and a sheave interposed at both ends.
And a second flyer in which a double-twisted stranded wire wound on the first or second winding drum in the first stranded wire step is provided with sheaves at both ends. And a second stranded wire step of twisting it four times and winding it on a winding drum constitutes a method for producing a stranded wire.

[0006]

The method for manufacturing the stranded wire configured as described above is as follows.
The first twisting step of twisting twice and the second twisting step of twisting four times can be performed simultaneously.
