Embodiment Construction

[0043] refer to figure 1 , the weft thread contact 10 is used on a water-jet loom that uses strip-shaped flat threads as weft threads 12 and warp threads 14, and is used to weave strip-shaped (ribbon-shaped) base fabrics, that is, weaving cloth 16. . It can also be used on looms that use flat yarns only as weft yarns 12.

[0044] The weft thread 12 is ejected from the weft injection nozzle without the icon at the same time as the pressure water for weft insertion, and is inserted in the opening of the warp 14 with the thickness direction as the up and down direction, Weft thread is driven into the place just woven by reed 18 to weave as weaving cloth 16.

[0045] The weft thread contact 10 comprises: a contact body 20 formed in an L-shape when the boundary of the base and the front end is bent and viewed from a plane; The front end portion is a pair of guide members 22 and 24 used as a guide device for the weft yarn 12 . In more detail, the touch element main body 20, comp...

Abstract

The present invention discloses a weft feeler, which has a slit allowing passage of weft accompanied by beating motion, especially a method capable of precisely detecting the weft. Within the weft feeler, which has guide parts extended within an area at least comprising a territory closer to an entrance of the weft than a light axle of a slit formed onto a feeler body along an extension direction of the slit, and disposed with space left in a weft entering direction overlapped towards the slit, a method of weft detection is characterized in that accompanied by the beating motion, the entered weft is detected by being passed through the slit while being engaged by the guides.

Description

technical field [0001] The invention relates to a weft contactor and a weft detection method in a shuttleless loom with a spinneret chamber. Background technique [0002] So far, when using thin plate-shaped so-called strip-like weft yarns (flat yarns, flat yarns) to produce strip-shaped woven fabrics (base fabrics), sword-belt looms are often used. But the sword-belt loom has its limitations in increasing the productivity of weaving. At present, weft injection components such as weft injection nozzles or weft thread contacts have been improved, and water jet looms can be used to weave cloth strips gradually. [0003] Among the weft contact elements that can detect the weft threads of jet looms, there is a kind of weft thread contact element that uses the pressure water for retaining part of weft throwing to make the weft thread pass through the slit (slit) along with reeding (beating, beating). , is arranged on the main body of the contact,...
