DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for connecting braids formed by a braider to form braided composites of various shapes and sizes. . The braid composite thus formed is:
The resin is cured as it is or after being impregnated with the resin, and is used as various members and components in various industrial fields.

[0002]

2. Description of the Related Art Conventionally, there has not been known a technique of connecting braids to form braided composites of various shapes and sizes. It is envisioned that the suture will form a braided composite.

[0003]

However, when the braid is simply sewn by conventional means, the needle cuts or damages the filaments of the fiber bundle, which is a bundle of filaments, constituting the braid. As a result, there is a problem that the strength of the sewn portion is reduced, and as a result, the strength of a braided composite manufactured by connecting the braids is reduced.

[0004] Further, in order to form a complicated shape or a large braid at a time with a braider, there is a problem that a very large braider is required and a track on which the bobbin carrier travels is complicated.

An object of the present invention is to provide a method and an apparatus for connecting braids to produce braided composites of various shapes and sizes by connecting the braids without reducing the strength of the connecting portions. Things.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention firstly provides a thin stitch hole formed in a braid of an overlapping portion of a braid or a overlapping portion of a braiding portion of a braid. Secondly, the thin member is inserted into the overlapping portion of the braid by a suturing member having a substantially hemispherical end portion, and the suturing is performed. A plurality of braids are connected in a sewn state by a strip member inserted by the member. Thirdly, the braid is formed by a perforated member having a substantially hemispherical tip. A suturing hole is formed in the overlapping portion, and a thin member is inserted into the suturing hole formed in the overlapping portion of the assembly by a suturing member to connect the plurality of assemblies in a sewn state.
