Embodiment Construction

[0027] Depend on figure 1 The reel holder generally designated 1 can be seen, from which the two strands 2 and 3 are withdrawn. The two strands of warp 2 and 3 are under tension and deflected by means of the yarn hold-down device 4 . The two strands of warp 2 , 3 are fed to the leno edge sewer indicated by 10 on the rear side, that is to say in the rear shed area H. Behind the leno edge sewer 10 are arranged a heald frame 20 as well as a reed 21 and a warp beam (baum) 22 which receives the fabric. The front shed V now extends from the twist point of the warp and weft yarns all the way to the leno selvedge. The leno edge selvedge 10 is shown with a motor drive 11 and two arms 12 arranged diagonally opposite each other, which constitute a "propeller" in this respect. The arm 12 has an eyelet 12a at the end to allow the strands 2, 3 to pass through. Arranged in the housing of the electric motor 11 are at least two magnets 13 and behind each a sensor unit 14 , for example in t...

Abstract

The present invention's topic is a device for detecting leno yarn breakages in the region of a leno selvedge-forming device in a loom. This leno selvedge-forming device having at least two arms for guiding at least two leno yarns which can mutually be entangled by the rotation of the arms is characterized in that the devices (12, 13, 14, 14a) for detecting the leno yarn breakages have devices (13, 14) for detecting the principal vibrations of the arms (12). And, the loom particularly having heald frames, at least one reversely rotatable leno selvedge-forming device, and a device for detecting for detecting leno yarn breakages is characterized in that the device for detecting for detecting leno yarn breakages is particularly disposed in a front side shed (V) between the leno selvedge-forming device (10) and the heald frames (20).

Description

technical field [0001] The invention relates to a device for measuring the breakage of yarns skeined in the region of a leno selvedge in a weaving machine, wherein the leno selvedge has at least two arms for guiding at least two skeins, wherein the arms The spinning yarns are twisted together. [0002] The subject matter of the invention is also a weaving machine with a heddle frame and at least one leno edge device (Dreherkanten apparat) whose direction of rotation is reversible, and a device for measuring yarn breakage on the twisted warp. Background technique [0003] The fabric has so-called "leno selvedges" on its two side edges. This leno selvedge prevents the fabric from unraveling. Various very different instruments are known for the manufacture of this leno selvedge; for example, a rotary selvage device for a loom is known from EP0674031, which has a so-called Yarn compass. With the aid of this known device it is possible to produce a so-called "full skein leno ...
