Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weaving method for weaving a tubular tissue body having a plurality of layers around a mandrel by using a braider device, and particularly, a boss type tissue body with a flange is seamlessly woven. TECHNICAL FIELD The present invention relates to a weaving method for weaving a radial direction weaving textured body that is integrally continuously woven, and a flanged boss type textured body and a disk type textured body woven by the weaving method.

2. Description of the Related Art As is well known, a method for weaving a tissue body has been developed and provided for weaving a tubular tissue body having a plurality of layers by a braider device. Conventionally, for example, when weaving the flanged boss type tissue body 21 shown in FIG. 6 with a braider device, as shown in FIG.
2 and the flange portion 23 were separately formed in advance, and after that, they had to be bonded to each other to rely on a weaving method for forming the flanged boss type fabric body 21 as shown in FIG. 6B.

The reason for this is that the set angle with respect to the axis is ± θ °.
When weaving a tissue body by selectively combining the braided yarn of No. 1 and the central yarn having an angle of 0 ° with the axis line around the mandrel to weave a tissue body, the tissue of the tubular portion 22 and the tissue of the flange portion 23 are essentially different. This is because this cannot be performed by the conventional weaving method. In this manner, the tubular portion 22 and the flange portion are separately formed in advance, and then the flanged boss type tissue body formed by adhering them together is the tubular portion 22.
Since the flange 23 and the flange 23 are adhesively bonded, there is a big problem of breakage at the bonded portion.
