部３側寄りとするのが好ましい。As described above, in this embodiment, the exhaust portion 3 and the accumulation adjusting portion 4 are elastically supported independently of each other, but they may be integrally supported. In addition, as the strength of the elastic support when independently supported, in the exhaust unit 3, since the high-pressure heating fluid flows from the injection nozzle 1c as it is,
A sufficient pressure-resistant seal is required as compared with the accumulation control unit 4,
In addition, since the movement of the yarn Y along the flow and the movement of each single yarn becomes active, it is preferable to prevent the yarn Y from catching on the division surface F as much as possible. On the other hand, in the accumulation control unit 4, since the heating fluid flowing from the injection nozzle is almost exhausted in the exhaust unit 3, the pressure is reduced, and a pressure-resistant seal as strong as the exhaust unit is not required. Also, since the yarn Y is accumulated in the accumulation chamber 4 to form a plug-like yarn lump, there is no situation in which the single yarn is easily caught. Therefore, it is preferable that the exhaust unit 3 and the accumulation adjusting unit 4 be configured separately, and that the exhaust unit 3 be provided with strong elastic support by a strong spring and the accumulation adjusting unit 4 be provided with weak elastic support by a weak spring. When the exhaust section 3 and the accumulation adjusting section 4 are integrated and elastically supported, the area of the dividing surface S becomes large, so that the position of the elastic member is set so that the sealing performance of the exhaust section 3 does not deteriorate. Is preferably closer to the exhaust unit 3 side.
