Referring to Figures 1a and 1b the operation of the conventional wire banding device having the configuration as described above are as follows.

First, the wound wire is mounted on a wire feed roller, passed through a wire warpage correction device 63 composed of a plurality of rollers 65 and inserted into a paper feed port of the paper feed supply 62 to continue to move forward. The synthetic resin material handle (H) is formed in the handle supply container (9) and when the switch is operated in the control box, the driving motor (M2) of the driving unit 75 is operated to transfer the driving force to the driving shaft and receive the driving force. The drive shaft rotates the interlocking shaft and the driven shaft half by rotating the gears M2-1, M2-2, M2-3 and M4-1 respectively. Then, the link section operates around the hinge point to move the paper feed port to one side on the guide guide to supply the wire inserted in the paper feed port.

When the supplied wire passes through the divided guide guides and the handles H supplied to the handle supply part 74 and other guide guides, the stopper 62-1 is operated at the end thereof to complete the supply.
