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 drawings.

[0035] water jet loom figure 1 As shown, the jet water from the weft insertion nozzle 1 fixed on the loom frame passes through the warp yarn opening area 2 and inserts the weft yarn, while the reed 4 supported on the reed holding part 3 is shaken .

[0036] The reed 4 is generally formed by inserting the upper and lower end portions of a plurality of elongated flat plate-shaped reed blades 5 in parallel at predetermined intervals, and inserting the upper and lower end portions of the plurality of reed blades 5 integrated by the coil springs 6 . The spinnerets 7 and 8 are housed in vertically opposing spinnerets 7 and 8 with U-shaped cross-sections. The spinneret 8 on the lower side is fixed to the reed holding member 3, and the reed holding member 3 is connected to an unillustrated rocking mechanism.

[0037] The first form of the weft insertion stabilizing...

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 perpendicularto 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 weft insertion by maintaining the straightness of jet water for weft insertion of a water jet loom. Background technique [0002] The water jet loom produces the phenomenon that the weft insertion jet water moves upward as it gets closer to the opposite side of the yarn feeding. This phenomenon is presumed to be due to the updraft generated in front of the reed due to the swinging motion of the reed in which a plurality of reed blades are arranged side by side between the upper and lower spinnerets (for example, refer to Patent Document 1). The principle of generating updraft is that when the reed retreats after beating, the reed concentrates the air on the cloth fell side, and then when the reed advances, the reed pushes back the concentrated air and makes it rise. The phenomenon of upward movement of jet water tends to occur at high speed and water saving, and sometimes the warp yarn is damag...
