Abstract

Es wird ein Verfahren zur Regelung der Fadenzugkraft eines laufenden Fadens beschrieben, welcher in einem Friktionsfalschdrall-Aggregat einer Falschzwirnkräuselmaschine gekräuselt wird. Bei dem Verfahren wird die Fadenspannung des laufenden Fadens hinter dem Friktionsfalschdrall-Aggregat gemessen und dadurch ausgemessen, daß die Fadenspannung über einen Zeitfilter und durch Vergleich mit einem vorgegebenen Sollwert in ein Verstellsignal für das Friktionsfalschdrall-Aggregat umgewandelt wird, wobei der Regelbereich durch festgelegte Grenzwerte des Verstellsignals bestimmt wird. Erfindungsgemäß ist das Verstellsignal ein Stromwert und wird adaptiv über eine PI-Regler korrigiert, dessen Regelverhalten Quotienten aus Änderung der Fadenspannung und Änderung des Stromwertes berücksichtigt.

Figure 00000001
A method for regulating the thread tension of a running thread is described, which is crimped in a friction false twist unit of a false twist crimping machine. In the method, the thread tension of the running thread behind the friction false twist unit is measured and measured in that the thread tension is converted via a time filter and by comparison with a predetermined target value into an adjustment signal for the friction false twist unit, the control range being determined by defined limit values of Adjustment signal is determined. According to the invention, the adjustment signal is a current value and is adaptively corrected via a PI controller, the control behavior of which takes into account quotients from the change in the thread tension and the change in the current value.
