Problems solved by technology

As a result, the holding state of each weft yarn is different, and the holding of the end of the weft yarn connected from the farther nozzle will be insufficient, and the nozzle is likely to be detached, resulting in poor weft insertion.

Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0025] On a fluid jet loom, especially a water jet loom equipped with a fixed weft insertion nozzle that is not fixed on the sley but fixed on the frame of the loom, as shown in Figure 3, along the warp direction A weft yarn holding device 3 is arranged between a plurality of parallel weft injection nozzles 1 and the reed, and a cutter 5 as a weft yarn cutting device is arranged between the weft yarn holding device 3 and the cloth fell 4 .

[0026] The first example of the weft yarn holding device of the present invention figure 1 As shown in FIG. 3 , it is used in a device in which the number of weft insertion nozzles 1 aligned in the warp direction is two. Its structure is that there is a partition plate 7 between the weft insertion nozzle 1 and the warp yarn row 6, and the weft yarns 8 and 8 sprayed from the two weft injection nozzles 1 are separated by th...

Abstract

The weft-holding apparatus 3 has pressing boards 9 on upper and lower sides of a diaphragm 7 and forms a holding region 17 between the diaphragm 7 and each pressing board 9 and introduces weft ends continuing from two stationary weft-inserting nozzles arranged in parallel in the warp direction to a cloth fell side into a space between the diaphragm 7 and the each pressing board 9 and holds the wefts. In the weft-holding apparatus 3, a holding region 17 on the upper side and a holding region 17 on the lower side are differentiated under conditions viewed from a direction perpendicular to the diaphragm 7. As the differentiated aspect, in the weft end continuing from either stationary weft-inserting nozzle 1, the difference is given between a length passing through the holding region 17 on the upper side and a length passing through the holding region 17 on the lower side.

Description

technical field [0001] The invention relates to a weft yarn holding device arranged between a fixed weft insertion nozzle and a reed of a fluid jet loom. Background technique [0002] Weft yarns are respectively inserted from two weft insertion nozzles (corresponding to the fixed weft injection nozzles of the present invention) separated in the warp direction. The weft yarn is held on the yarn supply side by the weft yarn holding device through the beating motion, and the part between the weft yarn holding device and the reed is cut by the weft yarn cutting device. The cut weft yarn end is held by the weft yarn holding device until the next weft insertion, and the holding is released by the fluid jet from the nozzle to perform weft insertion. As the weft yarn holding device, there is known a disc-shaped member (equivalent to the push plate of the present invention) on the upper and lower sides of the partition plate, and the weft yarn is respectively held between the upper ...
