Embodiment Construction

[0021] in figure 2 In the loom shown, the two leno threads 2 and 3 pass through the thread compensator 6 or 7, the fixedly positioned thread guide 8, the warp automatic stop device 9, and the device 10 according to the present invention each from a thread supply The spool (for example, the spool 4 or 5) is brought to the heddle device 11. It can be seen from DE3818680 C1 that the twisted heddle device 11 can be composed of two lifting heddles 12 and 13, and the lifting heddles 12 and 13 can interact with the twisted heddle 14, so that each lifting heddle 12, 13 can lift the twisted heddle 14. The warp beam 15 with the warp threads 16, the shed forming device 17, the reed 18, and the cloth shaft 19 are also schematically shown. The leno thread 2 guided through the twisted heddle 14 is also called a fixed leno thread, while the leno thread 3 guided around the twisted heddle 14 and between the associated lifting heddles 12, 13 is also called an alternating leno thread. Line or ...

Abstract

A device (10) for the tensioning of a leno thread (2, 3) for a doup heddle device (11) which can be positioned in proximity to the doup heddle device (11 ), wherein the device (10) comprises for at least one leno thread (2, 3) a resiliency mounted thread guide (20) which forms a bending point (21) for the leno thread (2, 3), wherein the device (10) also comprises a fixedly mountable thread guide (30) which forms a bending point (31) for the leno thread (2, 3) which in use is positioned in proximity to the doup heddle device (11). A weaving machine which comprises a device (10).

Description

technical field [0001] The invention relates to a device for tensioning a leno thread of a heald heald unit of a loom, and a loom with the device. Background technique [0002] In weaving machines it is known to apply leno heddles, also known as leno heddles, to form leno weaves using known fixed and alternating leno threads and weft threads. In this case, the two leno threads are each brought from a thread feeder to the twisting heald device via the thread compensator, the fixedly positioned thread guide, the thread breakage stop device and the thread pressing member, and the twisting heald device Consists of two lifting heddles interacting with twisted heddles. Although there is a thread compensator near the thread feeder, such heald heald devices cannot accommodate the difference in leno thread length caused by the up and down movement. This is also accompanied by an undesirably large change in tension in the leno thread. This also leads to the inability to form a good...
