Abstract
A method and apparatus measures the tension of an advancing yarn which is subject to interruptions of the yarn path, resulting for example from the severance of the yarn. During such interruptions, the zero setting of the tension sensor does not always return to zero, thereby providing an erroneous output reading during subsequent yarn advancing cycles. In accordance with the present invention, a circuit is provided which identifies such errors and sounds an alarm when the error exceeds a predetermined limit. Also, the erroneous output signal is input as the zero point signal for the subsequent yarn advancing cycle, and during such subsequent cycle, the tension is determined on the basis of the newly set zero point.
