In addition, when the vertical bar 252 is transferred relatively slightly upward and the cutter 253 is separated from the outer circumferential surface of the alignment roller 251 in a non-contact state, the roller arm 251a is moved by the attachment drive unit 261 as shown in FIG. 6 (a). After being transferred to the front bobbin 20, the alignment roller 251 is rotated, and the rear adhesive strip B2 together with the plurality of yarns 1 is engaged between the alignment roller 251 and the clamp roller 255. Then, as shown in FIG. 6 (b), the attachment roller 262 is conveyed downward to attach the rear adhesive strip B2 to the outer circumferential surface of the front bobbin 20.

In the warping bobbin replacement step (S40), the moving winding means 260 is provided in the distal end alignment module 250, and the moving winding means 260 is installed on the warping body 221, and the roller arm 251a Attachment drive unit 261 for controlling the movement in the lateral direction, and an attachment roller 262 installed on the roller arm 251a and conveyed downward by cylinder operation to press the rear adhesive strip B2 toward the outer circumferential side of the front bobbin 20 ),
When the winding of the yarn 1 on the front bobbin 20 is completed, the plurality of yarns 1 disposed in the front and rear areas based on the alignment roller 251 are attached to the front and rear adhesive strips B1 and B2. bundled and attached with
The vertical bar 252 is transported downward, and the clamp roller 255 first comes into close contact with the outer circumferential surface of the alignment roller 251 to restrain the plurality of strands of yarn 1, and then the cutter 253 is transported downward so that the yarn 1 ) After cutting, the front adhesive strip (B1) is attached to the outer circumferential surface of the yarn (1) wound around the warp bobbin (20), and the warp bobbin (20) is replaced,
When the vertical bar 252 is transferred relatively slightly upward and the cutter 253 is separated from the outer circumferential surface of the alignment roller 251 in a non-contact state, the roller arm 251a is transferred to the front bobbin 20 side by the attachment drive unit 261 After this, the alignment roller 251 is rotated, and the rear adhesive strip B2 together with the plurality of strands of yarn 1 is engaged and fed between the alignment roller 251 and the clamp roller 255, and then the attachment roller 262 ) is transported downward to attach the rear adhesive strip (B2) to the outer circumferential surface of the front bobbin (20),
The alignment roller 251 is rotated to feed multiple strands of yarn 1, and at the same time, the warping bobbin 20 is rotated to wind the yarn 1 several times, and then the attachment roller 262 and the clamp roller 255 move upward. Yarn cutting method for fence netting, characterized in that the roller arm (251a) is provided to be returned and then conveyed.
