PURPOSE:To prevent clogging of yarn remaining in a draft zone in a fluid false twist device, by stopping feed of raw material in occurrence of end breakage, stopping the fluid false twist device after a given time is passed. CONSTITUTION:When end breakage detector 14 is operated, the relay 15 is worked to close the contact point, a sign is sent to the back roller part 1a of the draft device 1 to operate a stopper, and feed of the stable fiber bundle Y is stopped. Yarn spun from the fluid false twist device 5 is sucked in the pneumatic device 8, and taken out from the pneumatic duct 10. The delay relay 16 is operated, a sign is sent to the solenoid valve 7, and feed of compressed air to the fluid false twist device 5 is stopped. After operation of treatment of yarn is over, the fluid false twist device made into an operative state, a device to stop feed of raw material is made into an inoperative state, the raw material is fed, and spinning operation is continued. |
