Die Neuerung betrifft einen Füdenzagkraftmesser t?a·: =i 4»v Oberbegriff des Anspruchs i.The innovation concerns a force measuring device t?a·: =i 4»v generic term of claim i.

Fadenführer v;--<i ein Per~anent«agnet angeordnet sind. Des Pereanentaague' gegenüber ist eine Railsc.sC" installiert, die jede Bewegung, welche von de · Blattfeder ausgeht res'-triert.

Dieses Federeleaent hat aber, wie jedes schwingende Eleaer<t,eJne Eigenfrequenz. Hinzu koamen noch Schwingfrequenzem seitens der Maschine, die sich Bit der Eigenfrequenz der Feder überlagern. Die Folge hiervon sind Fehlaessungen.DE 35 OS 698 C2 describes a thread spring which has a leaf spring clamped on one side and at the end of which a thread guide and a permanent magnet are arranged. A rail sensor is installed opposite the permanent magnet, which restrains every movement that comes from the leaf spring. Of course, only movements that are triggered by the spring, i.e. different thread tension forces, should be registered. However, like every vibrating element, this spring element has its own natural frequency. In addition, there are vibration frequencies from the machine which overlap with the natural frequency of the spring. The result of this is incorrect measurements.
Es ist Aufgabe der Neuerung, den Fadenzugkraftnesser so zu gestalten, daß bei einfache* Aufbau Fehlaessungen vermieden werden.The aim of the innovation is to design the thread tension meter in such a way that incorrect measurements are avoided with a simple* structure.
Die Lösung dieser Aufgabe ist dea kennzeichnenden Teil des Anspruchs 1 zu entnehmen. Weitere vorteilhafte Ausgestaltungen enthalten dl*» An-The solution to this problem can be found in the characterizing part of claim 1. Further advantageous embodiments contain the following:
Bei dem neuerungsgemaßen Fadenzugkraftaesser weist die einseitig eingespannte Blattfeder eine auf die jeweilige Frequenz abstimmbare Dämpfung auf. Vorteilhafterweise ist diese Dämpfung auf der Blattfeder einstellbar, so daß je nach Maschinenfrequenz oder Federfrequenz eine enfspre-In the new thread tension meter, the leaf spring clamped on one side has a damping that can be adjusted to the respective frequency. Advantageously, this damping can be adjusted on the leaf spring, so that depending on the machine frequency or spring frequency, a corresponding

Die Masse ist vorzugsweise aus einem Fluor-Kautschuk, der gegen Spinnpräparationen beständig ist. Darüberhinaus muß die Masse temperaturunabhängig, elastisch und hochdämpfend sein.The mass is preferably made of a fluoro rubber that is resistant to spin finishes. In addition, the mass must be temperature-independent, elastic and highly dampening.
Die Dämpfungsmasse kann aber auch fest mit der Blattfeder, z.B. durch
vulkanisieren, verbunden sein.
An einem Beispiel soll die Neuerung noch näher erläüte- i. werden.The damping mass can also be firmly connected to the leaf spring, e.g. by vulcanization.
The innovation will be explained in more detail using an example.
