Heat-treated by heat treatment in a state.

Then, the plated copper wire is guided through the plating bath in which the plating solution is stored by guiding the heat-treated copper wire, and the cooling solution is cooled through the cooling bath, and then the copper plated copper wire is wound on the winding bobbin by a winding device. do.

However, in the conventional multi-stage rolling apparatus, since the cylindrical boss on which the rolled flat line is wound and the H bobbins formed at right angles of the supporting portions provided on both sides are rotated at a constant speed, the circumferential distance of the winding portion after the initial stage of the flat line and after some progress is achieved. Since there is a problem that the winding speed of the flat line is changed.

In addition, since there is no tension sensing means for controlling the first heat treatment roller and the second heat treatment roller, the movement speed of the copper wire passing through the first rolling part and the second rolling part is the movement speed of the copper wire passing through the first heat treatment part and the second heat treatment part. There was a problem that the difference between the thickness and width formed unevenly during the heat treatment of the copper wire.

The conventional method as described above is significantly reduced workability and productivity has an impact on the production cost.
