Embodiment Construction

[0043] The tensiometer T in Fig. 1 as the main element has a substantially straight torsion element F, a photoelectric scanning device A, and a filamentary arm D; on some extendable material M, for example, a filamentary material Y, A tensiometer can test its stress.

[0044]The torsion element F is, for example, made of disc material or tubular material. For example, the elastic steel wire has a pole 5, and one end 4 of the pole can be used as a wire arm D, which is bent in a direction perpendicular to the pole 5. The other end 6 of the pole 5 is also bent here. The torsion element F is fixed firmly together with the end 6 at the support means 3, next to the filiform arm D, in the swivel bearing 2, the post 5 is supported, but twistable. In order to guarantee the distance from the twisted axis of the threaded material Y turned around on the threaded arm D in the contact range 4' to the mark bar 5, the threaded material Y can be introduced into the threaded material introduc...

Abstract

The invention relates to a tensometer (T) for measuring the tension of filiform materials. The inventive tensometer comprises a thread arm (D) connected to an incorporated torsion element (F) and an optoelectronic detection device (A) for a large scale measurement of the torsion of the torsion element (F) on an optical trajectory with the aid of a light position sensor (P) when the threads are tightened.

Description

technical field [0001] The invention relates to a tensiometer for measuring force on a filamentary material, comprising a torsion element fixed at least at one end, a filamentary arm connected to the torsion element and in contact with the filamentary material, the torsion element encircling the torsion axis The twist is dependent on the tension of the filamentary material and includes an optoelectronic twist detection device comprising a receiver with a reference plane and a light source, the light from the light source impinging on the reference plane of the receiver. Background technique [0002] Tensiometers are used in the warp processing industry or in the field of textile technology. Measuring the tension is to obtain the working condition of the knitting machine, adjust the machine within the range of the tension of the thread, and let the warp thread weave into the machine. [0003] Tensiometers are defined in patent EP 0 288 784, which allow free entry and exit of...
