Embodiment Construction

[0021] exist figure 2 In the loom shown, the two leno threads 2 and 3 are each supplied from a thread compensator 6 or 7, a fixedly positioned thread guide 8, a warp break stop device 9, and a device 10 according to the invention. The device (eg bobbin 4 or 5) is brought to the heald heald device 11. It is known from DE3818680 C1 that the twisted heald 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 heald 12, 13 can lift the twisted heald 14. A warp beam 15 with warp threads 16, a shedding device 17, a reed 18, and a cloth beam 19 are also schematically shown. The leno threads 2 guided through the leno healds 14 are also called fixed leno threads, while the leno threads 3 guided around the healds 14 and between the associated lifting heddles 12, 13 are also called alternating lenos line or alternate lines.

Abstract

A device (10) for the tensioning of a leno thread (2, 3) for a doup heddle device (11) 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 leno threads of a heald heald device of a loom according to the preamble of claim 1 and to a leno yarn with the device according to the preamble of claim 10 loom. 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 lar...
