Abstract (en)

In an individual-spindle-drive type double twister comprising a spindle motor 3 for each spindle that drives a spindle shaft 1 and twists a yam Y that forms a balloon around a yarn supplying package P while simultaneously winding the yarn, a yarn tension detection device 11 for outputting a tension detection signal depending on the variation of the tension of the travelling yarn Y while in contact with the yarn Y is provided adjacent to a balloon guide 5 that converges the balloon, on the downstream side of the balloon guide 5, and a display device 16 is also provided to display uniformity (p) and temporal waveforms as information indicating the temporal variation of the tension detection signal. The present invention thus enables even a small variation in balloon tension to be accurately recognized and also enables inappropriately produced packages to be identified. <IMAGE>
