Problems solved by technology

The phenomenon of upward movement of the jet water tends to occur at high speed and water saving, and sometimes the warp yarn is damaged by the upward movement of the jet water
Therefore, in order to allow the jet water to pass through the warp yarn opening, it is necessary to increase the pressure of the jet water from the weft insertion nozzle to enhance straightness, or to adjust the jet direction in consideration of the amount of upward movement, which is difficult to adjust.

Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0035] The water jet loom is shown in Fig. 1. The water jet from the weft insertion nozzle 1 fixed on the loom frame passes through the warp yarn opening range 2 and wefts the weft yarn, while keeping the support on the reed. The reed 4 on the part 3 is rocked.

[0036] The reed 4 is usually formed by inserting the upper and lower ends of a plurality of elongated flat plate-shaped reed pieces 5 into the coil spring 6 in parallel at a predetermined interval, and integrating the upper and lower ends of the plurality of reed pieces 5 by the coil spring 6 . The structure is accommodated in the spinneret caps 7 and 8 having a U-shaped cross section facing up and down. The lower spinneret cap 8 is fixed to the reed holding member 3, and the reed holding member 3 is connected to a swing mechanism not shown.

[0037] The first mode of the weft insertion...

Abstract

Provided is a device for keeping the straightness of water jet for weft insertion of a water jet loom and stabilize the weft insertion. The weft insertion stabilizing device of a water jet loom is composed of a member 9 integrated to or separated from the upper or lower spinnerets 7, 8 of a reed 4 or a reed holding member 3 and extended out of the warp opening range to the side of the cloth fell 10. The member 9 may be placed above or below the tip range 17 of the water jet ejected from the weft insertion nozzle 1 to the reed dent 5. The extending direction of the member 9 may be perpendicular to the longitudinal direction of the reed dent. The tip end of the member 9 may have a curved part opened at the side of the reed dent.

Description

technical field [0001] The present invention relates to a device for stabilizing the weft insertion by maintaining the straightness of the water jet for weft insertion of a water jet loom. Background technique [0002] The water jet loom produces a phenomenon in which the jet water of the weft insertion moves upward as it approaches the opposite side of the feeding yarn. This phenomenon is presumed to be caused by the rocking motion of the reed in which a plurality of reed pieces are arranged in parallel between the upper and lower spinnerets, and an upward airflow is generated in front of the reed (for example, refer to Patent Document 1). The principle of generating updraft is that when the reed retreats after beating up, the reed concentrates the air on the weaving fell side, and then when the reed advances, the reed pushes back the concentrated air and makes it rise. The upward movement of the jet water is likely to occur at high speed and water saving, and the warp yar...
