Since the leveling upper roll 207 has a smaller diameter than the leveling lower idle roll 209 and the leveling lower driving roll 210, the leveling upper roll 207 removes the cushioning action and tension of the band 117 when the band 117 is wound and reduces the shape. By correcting, the band 117 is tightly and compactly wound on the winding head 115.

When the upper and lower shaft home position touch bars 313 and 315 mounted on the rear end of the winding head 115 detect any one of the upper and lower shaft home position sensors 312 and 314, the automatic rotation is stopped and the winding operation of the band 117 is completed. Done.

In the sixth step 405, the band clip unit installed at the top of the frame 108 starts to clip the winding band, and the clip case 300 waiting for the clip case home position sensor 301 is traversed through the clip case. As the cylinder 302 moves forward, it swings around the fixed frame deck 319.

The clip case 300 swings to a band position bound to the winding head 115, and the clip outlet 309 is positioned at the center of the clip groove 316 formed on and below the winding head 115.

In the clip case 300, two springs 307 are fixed to the upper spring fixing plate 306, and the lower clip touch bar 308 moves up and down to process the grooves on the side, and moves the clip 310 to the clip case. (300) leads to the clip exit (309).

Finally, the seventh step 406 is to prepare the band binding in the swing state that the guided clip 310 is already located in front of the winding head 115, so that the clip outlet 309 is easy to seat on the wound band The clip exit 309 is rounded, and the clip ejecting plate 311 is advanced by the clip push cylinder 305 along the guide groove formed in the clip case 300 to bind the band. The clip 310 is pushed into the clip groove 316 positioned in front of the winding head 115 to form the binding band 119.

The presence of the clip 310 in the clip case 300 is such that when the clip touch bar 308 detects the lower clip detection sensor 304, the operator confirms that the clip 310 is absent and opens the door handle 317. If the clip 310 is opened and the upper clip detection sensor 303 is detected, the clip is inserted.

When the binding operation of the band 119 is completed, the operation is performed by the reverse order of the above steps, and the binding band 119 is dropped along the chute 105 to the conveyor 106 to the scrap box 107.
