い。In each of the tension devices of the above-mentioned weights, the adjustment range of the tension is not so large, and the tension cannot be absorbed in a large slack of the yarn. By the way, the applicant of the present invention has previously described an apparatus for manufacturing an I-shaped cylindrical assembly, an apparatus for manufacturing a cylindrical assembly that forms a plurality of branches at an acute angle, and is integrated with each other at the branch point. We have developed braid manufacturing devices with a three-dimensional structure, but the trajectories of these devices have a large difference between the part near and far from the composition point, and there is a large difference in the yarn length drawn from the bobbin B. . Therefore, when each of the above-mentioned weights is used in these composition devices, when the weight moves from a portion far from the composition point to a portion close to the composition point, the slack of the yarn drawn out from the bobbin B is sufficiently absorbed. And can't get a tight braid.

The coil tension increases gradually and the thread tension gradually increases .
The engagement is loosened as the outer diameter of the large diameter portion becomes substantially equal, and the urging of the bobbin in the reverse rotation direction is released. By repeating such biasing and release, the thread tension is maintained at a substantially constant value with a very small fluctuation. In addition, when operating using a three-dimensional structure braid manufacturing apparatus, when the weight is moved from a position far from the composition point to a close position, the bobbin is moved in the opposite direction by the urging force of the tension device. The spinning and loosening thread is wound on a bobbin.

On the other hand, the inner diameter of the coil spring 3 is slightly smaller than the outer diameter of the bobbin support large-diameter portion 2a. The upper portion of the coil spring 3 is twisted to increase the inner diameter, and is attached to the bobbin support large-diameter portion 2a. When the torsion is released, the coil spring 3 tightens the bobbin support large-diameter portion 2a,
Engage as if hugging. A cap 9 for preventing the bobbin B from jumping out is screwed to the upper end of the bobbin support 2.

る、ほぼ一定と見なせる糸張力下で組成される。The bobbin B is inserted into the bobbin support 2 in the bobbin machine thus constructed, and after a predetermined threading operation, the yarn Y is pulled out from the bobbin B to pull out the bobbin B. The bobbin B rotates while being guided to the composition point located above the center of the bobbin (withdrawn by 1 to 2 m), and the rotation is transmitted to the coil spring end hooking body 4 by the pin 8, and the coil spring 3 is twisted, Its diameter increases. When the diameter of the coil spring 3 is increased beyond a certain value, the bobbin support large-diameter portion 2
a, the coil spring 3 slips and rotates between the bobbin support large-diameter portion 2a, and the rotation releases the twisting force of the coil spring 3 to reduce the diameter. Engage with the diameter part 2a. In the meantime, the thread tension is adjusted by the coil spring 3 and the bobbin support large-diameter portion 2.
rises linearly until it slips between
Every time slip and engagement are repeated, very small fluctuations are repeated. Therefore, after the yarn Y is set, the composition is made under a yarn tension that fluctuates very little and can be regarded as almost constant.

When the weight is moved from a distant position to a near position, the yarn tends to loosen greatly, but the bobbin B rotates in the opposite direction while releasing the torsional force accumulated in the coil spring 3,
The yarn is wound on bobbin B.
