摘要： Calibration of a thread tensioning force meter on a texturing unit for a false twist machine was previously performed differently depending upon the direction of withdrawal, that is forwardly or rearwardly, of the thread from the texturing unit. The thread passes the tensioning force meter by passing over a spring biased support abutment connected with a meter. In the invention, the outlet past the tensioning force meter includes a withdrawal point and slightly upstream of that point a calibration point, which points are separated by a thread eye through which the thread passes. The location of the calibration point is selected with respect to the withdrawal point and with respect to the position of the abutment engaged by the thread that regardless of whether the thread is withdrawn forwardly or rearwardly of the meter, the thread continuously contacts the calibration point. In one direction of withdrawal, the thread only contacts the calibration point. In the opposite direction of withdrawal, the thread first contacts the calibration point and then contacts the thread guide outlet, which holds a thread passing through the thread eye against the calibration point.

摘要翻译： 根据来自变形单元的线的向前或向后退出的方向，先前对假捻机的纹理单元上的线张力力计的校准进行不同的选择。 螺纹通过张紧力计，通过与仪表连接的弹簧偏压支撑支座。 在本发明中，经过张紧力计的出口包括提取点，并且在该点稍微上游一个校准点，该点由线程通过的线眼分开。 校准点的位置相对于提取点选择，并且相对于由螺纹接合的基台的位置而选择，无论线是否从仪表向前或向后抽出，线都连续接触校准点。 在退出的一个方向上，线程只接触校准点。 在退回的相反方向上，螺纹首先接触校准点，然后接触导纱器出口，该导纱器出口保持穿过线眼的螺纹抵靠校准点。
