問題点がある。Therefore, as a method for detecting abnormal yarns in the drawing false twisting process, a method has been proposed in which, for example, as described in Japanese Patent Publication No. 59-3573, unevenness in untwisting tension is detected using a tension meter. . However, this method detects abnormal yarns based on fluctuations in the yarn tension, and since the yarn is brought into direct contact with the tension detection part during processing, white powder may accumulate on the detection part and defects other than yarn irregularities may occur. Depends on the factors. There is a problem that an abnormality is detected and it is difficult to clarify the relationship between the abnormal tension and the abnormal yarn.

runs and continuously detects uneven thickness or bulky unevenness of yarn Y as a capacitance deviation signal. Regarding the detected deviation signal, the frequency signal below a specific frequency is full-wave rectified1.
Next, the full-wave rectified waveform is integrated. When the voltage of the integrated waveform reaches a predetermined voltage or higher, it is detected as abnormal untwisted yarn, and at the same time, the yarn cutter 3 disposed immediately before the supply roller 5 is operated to cut the yarn.

ができる。The thickness unevenness or bulky unevenness of the yarn Y is expressed by the amplitude of the waveform as shown in FIG. In particular, the waveform detected as abnormal untwisted yarn has a large waveform amplitude and a lower waveform frequency than that of a normal yarn, as shown in b. In order to reliably detect these abnormal untwisted yarns,
By front-rectifying the waveform (■) in FIG. 1 and further integrating it, a waveform as shown in (■) can be obtained. It is clear from this waveform that abnormal untwisted yarn occurs when the voltage is above a certain level, and the abnormal untwisted yarn can be easily detected. At this time, by simultaneously operating the yarn cutter placed just before the supply roller,
False twisting can be stopped without winding up abnormally untwisted yarn.
