[0007]

In the present invention, since the rotary shaft is parallel to the rotary shaft of the grooved drum, even though the rotary shaft is installed in the narrow space in front of the winder, a large number of four rotary shafts can be formed on one rotary shaft. A peg can be attached, while one is in use, one is set to the take-out position of the empty tube, and another one is set aside to replenish the actual bobbin. You can keep it waiting. Therefore, the actual bobbin can be quickly supplied. Moreover, in the rotary shaft only is rotated 90 degrees, so the next full bobbin can be positioned at the supply position, the operation is very simple, to automate can perform a simple control equipment. Since the new real bobbin can be replenished to the empty peg while the real bobbin in use and the real bobbin in standby are used, the time required for replenishment can be increased and the number of winders owned by the worker can be increased. There is also a lot, and there is no need to stop the winder for bobbin replacement, which improves the operating rate of the winder. Furthermore, the thread feeding position of the actual bobbin
