ABSTRACT:
A yarn false twisting device in which two motors 30, 40 are installed separately for each of the drive shafts 30a, 40a of each false twist application element, and each motor is controlled by a control unit C in accordance with changes in the yarn tension. The installation of separate motors for each drive shaft of each false twist application element has enabled the elimination of complex power transmission mechanisms such as an endless belt or idler, making the yarn false twisting device more compact. Furthermore, each motor is controlled so as to rotate in mutually synchronic fashion according to changes in the yarn tension, improving the overall quality of false twisted yarn.
