The back roller 410 and the bag guide roller 420 are also rotated by the roller driving unit so that the sewing target 10 can be transported.

Also, the tension detecting roller 310 may be rotated by the tension detecting roller driving unit 320 to transfer the sewing target 10.

In the fourth step, the rotation speed of the first anti-creasing roller 210 or the rotation speed of the second anti-creasing roller 220 can be selectively controlled.

In the fifth step, the sewing process for the sewing target 10 can be performed.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be.
