この発明は、エアジェツトルーム用のオサ羽とその製造
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reed feather for an air jet loom and a method for manufacturing the same.
（従来の技術）
エアジェツトルームのオサ羽１には、第２図に示すよう

ａを設けた構造をより好ましい構造として提唱している
。Therefore, the peripheral portion 6.7.8 defining the recess, in particular its lower jaw edge 6, is provided with an inclined end face 6a which is inclined in the direction of restricting the air jet. Note that conventionally, the bottom edge 7 of the recess 3
It has been said that it is preferable that the mandibular margin 8 and the mandibular margin 8 be sloped end surfaces in the direction of restricting the airflow, similar to the maxillary margin 6.
and inclined end surfaces 6a, 8a in a direction that narrows the airflow to the mandibular edge 8.
, and the bottom edge 7 has an inclined end face 7 in the direction of diffusing the air flow.
A structure in which a is provided is proposed as a more preferable structure.

公報には、オサを組み上げてから、凹所３をパフで研磨
して、その研磨反力によるオサ羽の撓みを利用して凹所
３の周縁部分を斜めに研磨する方法が提唱されている。Conventionally, as a method for making the peripheral edge part 6.7.8 of the recess 3 of the reed feather into a predetermined inclined end face, the peripheral edge part of the recess is shaped by face punching after press punching, or by cutting during press punching. A method is used to create a slope depending on the conditions. As another method, Japanese Patent Publication No. 61-32416 discloses that after assembling the reeds, the recesses 3 are polished with a puff, and the periphery of the recesses 3 is A method of polishing the part diagonally has been proposed.
更に本願出願人は、上記特願昭６３−８９４４７号にお
いて、研削加工によってオサ羽の所望の周縁部分に傾斜
端面を形成する方法を提唱している。Furthermore, in the above-mentioned Japanese Patent Application No. 63-89447, the applicant of the present application has proposed a method of forming an inclined end face on a desired peripheral edge portion of the reed feather by grinding.
そして従来は、凹所３を画定する周縁部分を傾斜端面と
した後、バレル加工等によって周縁の角部を丸める丸め
加工を行っていた。Conventionally, after the peripheral edge portion defining the recess 3 is made into an inclined end surface, the corners of the peripheral edge are rounded by barrel processing or the like.
（発明が解決しようとする課題）
オサ羽の周縁２の丸め加工は、経糸内でのオサ羽の運動
を円滑にし、オサ羽との摺擦によって経糸が損傷するの
を避けるために必要であり、可能な限り、オサ羽周縁の
丸み半径を大きくするのが望ましい。(Problem to be Solved by the Invention) The rounding of the peripheral edge 2 of the reed feathers is necessary to smooth the movement of the reed feathers within the warp threads and to avoid damage to the warp threads due to rubbing against the reed feathers. It is desirable to increase the radius of roundness of the periphery of the feathers as much as possible.
しかし従来の方法では、オサ羽の周縁２に充分な丸みを
与えようとすると、凹所３を囲む周縁部分６．７．８に
形成した傾斜端面６ａ、７ａ、８ａも丸められてしまい
、傾斜端面にうねりが生じたり、傾斜角にばらつきが生
じる問題があった。However, in the conventional method, if an attempt is made to give sufficient roundness to the peripheral edge 2 of the reed feather, the inclined end surfaces 6a, 7a, 8a formed on the peripheral edge portion 6.7.8 surrounding the recess 3 will also be rounded. There were problems such as waviness on the end face and variations in the angle of inclination.
また従来の面打ちやプレス打抜き時の切断条件で凹所３
を囲む周縁部分を傾斜端面６ａ、７ａ、８ａとする方法
は、作業に時間がかかったり、形成される傾斜端面の精
度や平滑度が悪いという問題があった。In addition, under the cutting conditions of conventional surface punching and press punching, the recess 3
The method of forming the peripheral edges surrounding the slanted end surfaces 6a, 7a, and 8a has problems in that the work is time-consuming and the precision and smoothness of the formed slanted end surfaces are poor.
また、上記特公昭６１−３２４１６号公報で提唱された
方法は、凹所の底縁７を斜めにするのには有効であるが
、オサ羽の撓み方向の関係で、上顎縁６を斜めにするこ
とは困難であり、パフの移動に伴ってオサ羽に作用する
加工反力が連続的に変化するので、形成される面が緩い
中凸状の円弧面になるという問題もある。Further, the method proposed in the above-mentioned Japanese Patent Publication No. 61-32416 is effective for making the bottom edge 7 of the recess oblique, but due to the direction of deflection of the reed feathers, the upper jaw edge 6 is made oblique. It is difficult to do so, and since the processing reaction force acting on the reed feathers changes continuously as the puff moves, there is also the problem that the formed surface becomes a moderately convex circular arc surface.
更に、通常行われているような研削加工でオサ羽周面を
研削して傾斜端面６ａ、７ａ、８ａを削成する方法を採
用すると、荒砥石を用いると傾斜端面に研削痕が残り、
仕上げ砥石を用いると砥石の目づまりにより加工性が著
しく低下する問題があり、また研削反力によりオサ羽が
傾動して傾斜端面の角度にばらつきが発生する問題があ
った。Furthermore, if a conventional method of grinding the circumferential surface of the reed blade and cutting the inclined end surfaces 6a, 7a, and 8a is adopted, using a rough grindstone will leave grinding marks on the inclined end surfaces.
When a finishing whetstone is used, there is a problem in that the grindstone becomes clogged, resulting in a significant decrease in workability, and there is also a problem in that the reed blades tilt due to the grinding reaction force, causing variations in the angle of the inclined end face.

．． 6.7.8 is rounded, and then the peripheral edge portion 6.7.8 defining the recess 3 is formed with inclined end surfaces 6a, 7a, 8a, and the inclined end surfaces 6a, 7
The above-mentioned problem is solved by employing an abrasive grain processing process using a polishing tool 11 having a flexible base in the process of forming a and 8a. In this case, the reed blades can be manufactured efficiently by stacking a large number of reed blades 1 with their plate surfaces inclined and performing the abrasive processing described above.

気流Ｘを絞る側に傾斜することはない。Furthermore, the reed feather manufactured by the above method is characterized in that the peripheral edge of the recess 3 has a truncated arc-shaped cross section having inclined end surfaces 6a, 7a, and 8a. Feathers cannot be manufactured using conventional manufacturing methods. In the reed feather of this invention, the end surface 6a, which is a truncated surface of the maxillary edge 6, is inclined in a direction that narrows the airflow X. bottom edge 7
The direction of inclination of the end surface 7a changes depending on the arrangement interval of the reed feathers, etc., but it is at least thicker than the end surface 6a of the maxillary edge (it does not incline toward the side that restricts the airflow X).

一になる。(Function) According to the manufacturing method of the present invention, after the reed feathers are rounded by barrel processing or the like, the inclined end surfaces 6a, 7a, 8a of the peripheral portions 6.7.8 of the recesses 3 of the reed feathers are Since it is molded, the flatness and angle of the inclined end surfaces 6a, 7a, and 8a are not impaired by rounding. Also, the inclined end surface 6
Since the processing of steps a, 7 a, and 8 a is performed with the polishing tool 11 equipped with a flexible base with the reed blades 1 tilted and closely stacked, clogging will occur even if fine abrasive grains are used. Therefore, a smooth surface without scratches can be formed, and since no large processing reaction force is applied to the reed feathers 1, the angles of the inclined end surfaces 6a, 7a, and 3a also become accurate and uniform.
そして、上記方法により製造した本発明のオサ羽は、空

羽の摺擦による経糸の損傷も回避できる。The reed feathers of the present invention manufactured by the above method can guide the airflow X more stably, so that the flight of the weft threads is stable, and the movement of the reed feathers within the warp threads is smooth. Damage to the warp threads due to rubbing can also be avoided.

ある。The reed feather 1 has a recess 3 on its front side to form an air guide for guiding the weft yarn 4. The recess 3 is approximately U-shaped, and the upper jaw edge 6, the bottom edge 7, and the lower jaw edge 8 have an end surface 6a that is inclined with respect to the passing direction of the air flow X, as shown in FIGS. 1, 4, and 5. , 7a, and 8a. The direction of inclination of this end surface is such that the end surface 6a of the upper jaw edge 6 and the end surface 8a of the lower jaw edge 8 are in a direction in which the downstream side of the air flow X protrudes in the direction of the air flow (positive taper), and the end surface of the bottom edge 7 7a is a reverse taper in the direction in which the downstream side of the airflow X is away from the airflow and becomes lower.

とはない。The end surface 6a of the maxillary edge is always made to have a positive taper in order to guide the airflow from the sub-nozzle in the direction of the weft flying force. Further, the end surface 8a of the lower jaw edge is preferably made with a normal taper for boat fishing in order to prevent the flying weft 4 from being deflected downward due to gravity. Furthermore, the end surface 7a of the bottom edge has a reverse taper when the spacing between the feathers is narrow, and as it becomes wider, it has a parallel or normal taper, but it never becomes a normal taper with a larger inclination angle than the upper jaw edge 6.
