Similarly, the lower thread Y 2 is gripped between the clamp guide 6 and the clamp plate 7 (FIG. 1). Then, the thread end of the lower thread Y 2 is cut by the thread end cutter 8 at a position apart from the gripping position by a predetermined distance, and similarly, the thread end of the upper thread Y 1 is cut by the thread end cutter 9 (first (Fig. 1). At this time, the thread pressing lever 12 is pivoted to the non-acting position.

The yarn ends are drawn out from inside the untwisting nozzles 2 and 3, respectively. After that, the yarn pressing lever 12 is further actuated to swivel while guiding each yarn end, grasping each yarn end and at the same time ejecting compressed air from the yarn splicing nozzle 1 to entangle each yarn end and twist each other. It is added and the splicing is completed.

じて設けるようにする。In the untwisting nozzles 2 and 3 having such a structure, first, compressed air is supplied from the air supply passage 14b for a predetermined time, and a swirling air flow in the untwisting direction is ejected from the untwisting nozzle holes 24 and 25. As shown in FIG. 7, the untwisting nozzle holes 24 and 25 are opened toward the inner side of the untwisting nozzle, so that the jetting of the air flow causes a suction force as well as a swirling force. Therefore, the yarn end is sucked into the yarn introducing space 22, and is naturally brought closer to the yarn splicing nozzle 1 side where the yarn base exists, and moves through the slit 23 into the untwisting space 21. Then, it is untwisted by the swirling air flow. Next, while the supply of the compressed air from the air supply passage 14b is continued, the compressed air is supplied from the air supply passage 14a for a predetermined time, and the air flow is ejected from the untwisting nozzle hole 27 and the yarn introduction auxiliary nozzle 26. To be done. The suction force is increased by the air flow jetting from the yarn introduction auxiliary nozzle 26, and the yarn end, which was not sufficiently sucked only by the air jetting of the untwisting nozzle holes 24 and 25, is surely sucked. Further, the yarn end sucked in with a delay is also untwisted by the swirling airflow from the untwisting nozzles 24 and 25 that are continuously ejected. Thereafter, the supply of compressed air from the air supply passage 14b is stopped, and only the supply from the air supply passage 14a is continued for a predetermined time. Meanwhile, untwisting nozzle hole 2
The yarn ends of which the untwisting by the swirling air flows of Nos. 4 and 25 are completed are stretched by the airflow from the untwisting nozzle hole 27. As a result, the yarn ends untwisted in a coil shape by untwisting by the swirling airflow are also stretched, and the constituent fibers of the yarn ends are aligned substantially in parallel, reducing yarn splicing mistakes and obtaining good seams. To be The yarn introduction auxiliary nozzle 26 is provided if necessary.
