〈産業上の利用分野〉
本考案は空気噴射式織機に用いる補助ノズルに
関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an auxiliary nozzle used in an air-jet loom.
〈従来の技術〉
空気噴射式織機においては、主ノズルから噴射
される緯入れ用空気流の減衰を防止し、高速でか
つ確実な緯入れを行うという目的で、緯入れ通路
に沿つて適当な間隔で中空棒状の補助ノズルを並
設し、この補助ノズルの空気噴射口から補助空気
を噴射して緯入れを行うようにした方式の緯入れ
装置が用いられる場合がある。<Prior art> In an air injection loom, an appropriate weft is installed along the weft insertion path in order to prevent the weft insertion air flow injected from the main nozzle from attenuating and to perform high-speed and reliable weft insertion. A weft insertion device is sometimes used in which hollow rod-shaped auxiliary nozzles are arranged in parallel at intervals, and auxiliary air is jetted from the air injection ports of the auxiliary nozzles to perform weft insertion.

材料によれば所望の形状及び空気噴射口の穿設加
工がし易く、かつ硬質のメツキを施すことで表面
の滑らかさを確保すると共に、耐摩耗性を向上さ
せ得るという理由によるものである。 This auxiliary nozzle is usually fixed to the reed holder together with the reed so that it is located in the weft insertion path only during the weft insertion period. The auxiliary nozzle itself is small in weight so that the load during beating movement can be reduced, and the surface is smooth and there is no damage to the warp yarns. Conditions such as ease of use are required. Therefore, the auxiliary nozzles that have been used so far are made of thin plates or thin-walled tubes made of iron, copper, stainless steel, etc., which are shaped into the desired shape by appropriate processing methods such as pressing, welding, and brazing. In most cases, the air injection port is formed by drilling or electrical discharge machining, and the surface is hard plated. This is because easy and hard plating can ensure surface smoothness and improve wear resistance.

ルを提供するものである。<Means and effects for solving the problem> Therefore, in this invention, we focused on the use of ceramic, which has recently been attracting attention as a structural material, and used a composite material of metal and ceramic (cermet) as a material. Provided is an auxiliary nozzle in which an auxiliary nozzle in the shape of a hollow rod with its tip side pressed flat is integrally molded with a mold, and has an air injection port bored on one side of the flat part by electrical discharge machining. It is something to do.

is deformed and the auxiliary nozzle 1 is held and fixed. Then, the inside of this support 3 is attached to a lead holder (not shown). A distribution hole 7 communicating with the mounting hole 4 is formed in the support 3, and pressurized air supplied from a pressure air supply source (not shown) via an on-off valve is introduced into the distribution hole 7 of the support 3 through a pipe 8. Then, the air is supplied from the distribution hole 7 to the hollow part of the auxiliary nozzle 1 and is ejected from the air injection port 2.
