本考案は織機の綜絖枠を構成するサイドステー
に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a side stay that constitutes a heald frame of a loom.
（従来技術）
近時、織機の高速化に伴い、綜絖枠の軽量化が

確保しようとすれば重量が重くなり、軽量化の要
請に十分応えられないことになつていた。(Prior Art) Recently, as the speed of looms has increased, there has been a demand for lighter heald frames. Conventionally, side stays of heald frames have been made of light metal such as aluminum or plastic in order to meet the above requirements. However, especially in the case of the side stays of heald frames used in ultra-high-speed looms such as air jet looms and water jet looms, if we try to ensure rigidity that can withstand ultra-high speed rotation with the above-mentioned light metal materials or plastics, the weight will be too high. became heavier, and it became impossible to fully meet the demands for weight reduction.
この点の改善策として、軽くてしかも剛性に富

が、加工が面倒でコストが高くなる。 One possible solution to this problem is to construct the side stays from carbon fiber reinforced plastic (hereinafter referred to as CFRP), which is lightweight and highly rigid. However, side stays using CFRP have problems with vertical tensile strength and thickness direction bending strength when used in heald frames for ultra-high-speed looms. In order to maintain strength, it is also possible to use CFRP, which is a base material made of carbon fibers woven into a cloth, but this would be difficult to process and increase costs.

富んだものとなる。 The side stay main body 2 has a sandwich structure in which the honeycomb structure 21 is inserted as a core between the front and back skins 22, 22.
Since the honeycomb structure 21 is lightweight but has high rigidity, the honeycomb structure 21 as a whole is much lighter and more rigid than that made of aluminum.

On the other hand, when stainless steel plates are used for the skins 22, 22 on both sides, the skins 22, 22 due to friction with the guide member for guiding the heald frame up and down during operation of the loom.
It has the advantage of suppressing heat generation.

A hollow fitting part 23 is formed by partially cutting out the heald bar coupling member 2b, and the lengthwise (left and right) half portions of the heald bar coupling member 2b are fitted into this fitting part 23 and fixed by adhesive. As a result, the heald bar coupling members 2b, 2b are attached to both upper and lower sides of the side stay main body 2a, and the heald bar coupling members 2b, 2b are attached to both upper and lower sides of the side stay body 2a.
are fitted into the ends of the upper and lower heald bars 1, 1, and connected by screwing, caulking, gluing, etc.

By being integrated, it is provided so as to protrude from the outer peripheral surface of the side stay. In addition, by heating and pressurizing,
The reinforcement part 3 is the side stay main body (both side skins 22,
22) and the outer surfaces of the both-side connectors 2c, 2c, and are integrated therewith. In addition, the tape 3a
As is well known, carbon fibers are arranged parallel to each other on the same plane and are bonded together with synthetic resin, and are flexible before being heated and pressed, and can be attached to the sides in the same way as ordinary vinyl tape. It is wrapped multiple times around the outer circumference of the stay.

着固定するのが望ましい。 By providing the reinforcing portion (3) made of carbon fiber continuously over the entire circumference in the length direction of the side stay, the weight of the entire side stay is maintained, and the side stay main body 2a is effectively It is reinforced and given high strength, and in particular, the tensile strength in the vertical direction and the bending strength in the thickness direction are significantly increased. Therefore, the side stay as a whole is provided with high rigidity and strength that can sufficiently withstand the ultra-high speed rotation of the loom. Furthermore, compared to side stays made of CFRP, which is made of carbon fiber woven into a cloth-like material, it is easier to process and costs less.
Note that the reinforcing portion 3 may be provided over the entire width of the side stay main body 2a. On the other hand, the peripheral end surface of the side stay main body 2a is in an open state in which the honeycomb structure 21 is exposed to the outside, except for the attachment portion of the heald bar coupling member 2b. Although there is no particular problem in terms of strength in this state, in order to protect the honeycomb structure 21, it is recommended to glue and fix a cover member 4 made of plastic or the like to the open end face as shown by the imaginary line in FIG. is desirable.
