糸開口を通る緯糸に、緯入れ補助力を与えろ補助ノズル
に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an auxiliary nozzle for applying an auxiliary weft insertion force to a weft thread passing through a warp opening from a weft insertion nozzle in an air injection loom.
従来の技術

れ補助用空気を噴射する噴出口とで構成されている。Prior Art This type of auxiliary nozzle basically consists of a nozzle body disposed in a weft air guide extending in the weft insertion direction at the front of the reed, and a nozzle body disposed on the downstream side wall of the nozzle body. The nozzle is configured with an ejection port that injects weft insertion assisting air from a passage in the nozzle body toward the weft air guide.

As shown in Japanese Patent No. 35, it is known that a large number of small holes are assembled and separated from each other to form one ejection port. Also, the pore size is l.
６Ｊｌｊ＋程度の穴を噴出口にしたものも知られている
。It is also known that a hole of about 6Jlj+ is used as a spout.

の均一なものを得がたいということが指摘されている。Problems to be Solved by the Invention Since the structure is such that a large number of small holes are formed directly on the downstream side wall of the nozzle body, the small holes must be formed one by one by drilling or electrical discharge machining. It is necessary to make the diameter of the small hole about 0.2 mm. However, in the case of drilling, the drill diameter is approximately 0.
Since it is as thin as 2 mm, the holes must be drilled one by one, taking care not to break or shake the drill during drilling, which requires a great deal of effort and time. In the case of electrical discharge machining, the diameter of the discharge electrode is too small for the discharge voltage, so the discharge electrode is bent by machining heat during drilling, and the small hole is curved in the direction of its axis, making it difficult to maintain uniform injection direction. It has been pointed out that it is difficult to obtain things.
また１ 、 ６１１程度の噴出孔をドリルで形成すると

一の孔にならず、もって噴射方向が均一にならないとい
う不具合がある。Furthermore, when a jet hole of about 1,611 diameter was formed using a drill, particles were formed on the inner surface, and as a result, the jet direction was not uniform. In addition, when forming by electrical discharge machining, the corners of the electrode tip become rounded with use, so even if holes are formed under the same conditions, the holes will not be the same and the injection direction will not be uniform. There is a problem.
そこで本発明は、噴射方向が安定な噴出口の製作を容易
に行うことができる空気噴射式織機の補助ノズルを提供
するものである。Accordingly, the present invention provides an auxiliary nozzle for an air-jet loom, which allows easy manufacture of a jet nozzle with a stable jet direction.
問題点を解決するための手段 噴出口をノズル本体と一体に型成形しである。Means to solve problems The spout is molded integrally with the nozzle body.

を発揮する。According to the above embodiment structure, as shown in FIG. 9, a plurality of auxiliary nozzles 10 are arranged in the weft air guide 6,
When weft insertion assisting air is supplied to each of the nozzle bodies 12 of these auxiliary nozzles 10 from an air supply source (not shown), the weft insertion assisting air flows from the spout 13 of each auxiliary nozzle 10 to the weft air guide 6 downstream of weft insertion. Apply weft insertion assisting force to the weft yarn 18 that is jetted diagonally upward to the side and passes through the inside of the weft air guide 6 along with the jet airflow from the weft insertion nozzle 7. The weft insertion assisting air that has advanced through the passage 16 of the nozzle body 12 of No. 9 changes its flow approximately at right angles,
3, as shown in FIG. As a result, the air for assisting weft insertion that is injected from the jet nozzle I3 toward the weft air guide 6 is converged and ejected as shown by the dashed-dotted lines Q3 to I26 in FIG. In order to narrow the included angle θ, the injection directions in the vertical and horizontal directions are regulated to be approximately constant.By the way, the pressure of the weft insertion assisting air injected from the auxiliary nozzle to the weft air guide needs to be changed depending on the type of weft. However, by changing the type of weft yarn 18, even if the pressure of the weft insertion assisting air supplied from the air supply source to the passage of the nozzle body I2 is changed, the jet direction does not vary and the desired directivity can be maintained. Demonstrate.
