Problems solved by technology

The disadvantage of this embodiment is that, due to the warp threads running on the back rest and due to the reaction of the weaving process, vibrations occur on the skimming roller (Streichwalze) and thus also on the force-measuring mechanism, which can falsify the measurement results
Furthermore, due to the enormous forces acting on the back rest via the warp threads, this back rest needs to be designed to be relatively solid, which also makes accurate measurement of the warp thread tension difficult due to the consequently higher inertia

Embodiment Construction

[0036] figure 1 is a schematic side view of a loom 1 equipped with a measuring device 2 for measuring warp tension. The warp thread (Kettfäden) 5 here is usually unwound (abgewickelt) from the warp beam (Kettbaum) 4 of the conveying device 3 for conveying the warp thread and passes successively in the warp direction KR (see arrow) through the measuring device 2 for measuring the warp thread tension, The backrest 6 and the warp thread monitor 7 feed a shedding device 8 , which are usually oscillating and movable relative to one another in order to form a shed 11 . The rear rest has deflection elements 22 and can be designed in different ways, as will be explained in more detail with reference to the following figures. The weft insertion device is not shown, which can be designed in different ways and is sufficiently known in the prior art. Furthermore, the loom has a weaving reed (Webblatt) 9 , by means of which the inserted weft thread (Schussfaden) can be punched (angeschla...

Abstract

The invention relates to a device (2) for measuring warp thread tension in a weaving machine (1), comprising: a measuring element with two ends (17a, 17b) designed as a deflecting element (17), The warp thread (5) of the loom (1) can be guided through the steering element; the force measuring mechanism (18); and the frame ( 20) on the lever (21). The force-measuring mechanism ( 8 ) can be loaded by the measuring cell by means of this lever. The deflection element (17) is supported with one of its two ends (17a, 17b) on the lever (21) and with the other of its two ends (17a, 17b) in a non-movable manner On the frame (20) of the loom (1). The invention also relates to a loom (1) with a frame (20) and with at least one device (3) for feeding warp threads (5), said loom having at least one A device ( 2 ) for measuring warp thread tension is arranged downstream of a device ( 3 ) for conveying warp threads ( 5 ), comprising a diverting element ( 17 ) as measuring element.

Description

technical field [0001] The invention relates to a measuring device for measuring warp thread tension in a weaving machine, with a measuring element having two ends configured as a deflection element, through which the warp threads of a weaving machine can be guided. Furthermore, the measuring device comprises a force-measuring mechanism and a lever mounted rotatably about a fixed pivot point on the frame of the weaving machine, via which lever the force-measuring mechanism can be acted upon by the measuring element. Furthermore, the invention relates to a corresponding weaving machine with such a measuring device. Background technique [0002] Warp tension sensors are used in weaving machines in order to maintain a uniform warp tension during the weaving process which is required for uniform fabric formation and in particular for avoiding warp thread breakage. The warp thread tension is usually controlled or regulated by a correspondingly drivable warp thread tension, which...
