摘要： A spinning device, which is capable of preventing yarn, especially a truly twisted-like spun yarn, in produced packages from dyeing unevenly by controlling the tension, torque, and hairiness number of yarn, in piecing yarn,
The spinning device comprises a delivery roller (17) that delivers spun yarn Y formed in a draft device (4) and an air spinning part (5), a host controller (64) and sub controllers (31,32, and 36) that change the drive speed of a winding means (8) to a first drive speed in normal spinning or to a second drive speed in piecing yarn that is lower than the first drive speed, based on the result detected by a slab catcher (18). A sub controller (13) is also provided for changing jet air pressure of a rotating air current from an air spinning nozzle (19) in an air spinning part (5) to be high or low, based on the change in the drive speed.
