SUMMARY OF THE INVENTION The present invention attains the above object, and more specifically, a three-dimensional structure composed of a plurality of linear bodies individually supplied from a plurality of bobbins. In the method for producing a three-dimensional structure, a plurality of entangled portions are formed on the withdrawal side by twisting at least three of each of a large number of linear bodies supplied from the linear body supply side.

The present invention relates to a twisting tool that moves between a linear body and a twisted entangled portion of the linear body generated on a linear body supply side when the linear body is twisted and entangled to form an interlaced portion. By moving the linear body on the downstream side of the supply from the supply downstream side to the supply upstream side, the linear body on the downstream side of the supply can be supplied to the linear body distribution means in a state where there is no twisting.

And there is no difference in other configurations. That is, the rotating body 6 in the manufacturing apparatus for manufacturing the 4X tissue body ST2 is provided with the linear body receiving grooves 9 which are opened at an angular interval of 90 ° in the radial direction.

As described above, the three-dimensional 3X organization ST
1. Three-dimensional 4X organization ST2 and three-dimensional 6X-3X
When forming the tissue body ST3, in parallel with the formation of the first layer entangled portion Tw1 on the outlet side (pulling side) of the linear body distribution means 4, near the entrance side of the linear body distribution means 4,
In some cases, the twisted linear bodies may form a tangled portion. Therefore, an operation of using the shifting means 17 shown in FIG. 16 to shift the twisted tangled portion Jc of the linear body toward the supply upstream side of the linear body will be described. This is performed so as not to disturb the formation of the entangled portion Tw2 of the second layer. The operation of shifting the twisted entangled portion Jc of the linear body can be performed after forming the entangled portion Tw of each layer or after forming the entangled portion Tw of a plurality of layers. The entangled portion Tw1 of the first layer and the entangled portion Tw2 of the second layer shown in FIG. 2 are gathered one after another toward the upstream side of the supply of the linear body because the twisting direction of the linear body is reversed. Since the twist rotation direction of the linear body forming the twisted entangled portion Jc is also alternately reversed, the twist of the linear body gathered before and the twist of the linear body gathered later are mutually reciprocal. And all or a part of the twist at the tangled portion can be eliminated.

When twisting the linear bodies at intervals in the composition direction to form entangled portions Tw one after another, a continuous entangled portion of a plurality of layers is formed with the same twist rotation direction. Even if the torsional rotation direction is reversed at regular intervals, the operation of shifting the twisted entangled portion Jc of the linear body is performed every time the entangled portion Tw of each layer is formed, or is performed at regular intervals. This makes it possible to eliminate all or a part of the twists of the twisted entangled portions Jc gathered.

According to the apparatus for manufacturing a three-dimensional tissue according to the present invention, the three-dimensional tissue is constructed on the basis of the composition principle of the braid. Alternatively, a three-dimensional 6X-3X structure can be composed, and when these structures are provided in a fluid flow path of a distillation apparatus and applied as a packing for performing mass transfer, heat exchange, etc., a three-dimensional 3X structure is obtained. , The fluid is 3 from 3 directions
The fluid reaches the X-entangled portion and flows in three directions. In the three-dimensional 4X tissue, the fluid flows from the four directions to the 4X-entangled portion and flows in the four directions. −
In the 3X organization, the fluid flows from the 6 directions to the 6X interlaced portion and flows in the 6 directions, and each of them separates in the 3 directions to the 3X interlaced portion and flows in the 3 directions. It can be said that it is extremely effective in that it has an excellent processing function, reduces pressure loss and improves processing efficiency.

According to the method and the apparatus for manufacturing a three-dimensional structure according to the present invention, the entangled portions of the linear material which are generated on the side of the linear material supply side when viewed from the entangled portion of the three-dimensional structure are entangled. By moving the linear body on the downstream side of the supply to the next twist entanglement operation without twisting by moving the linear body on the downstream side of the supply from the supply downstream side close to the entangled part, the entangled part is formed smoothly It is possible to dramatically improve the production efficiency of a three-dimensional structure. Furthermore, according to the method for manufacturing a three-dimensional structure according to the present invention, the twist rotation direction of each linear body at the twisting entanglement point shifted to the supply upstream side is reversed at regular intervals, so that the three-dimensional structure is gathered before. Since the twist at the twisted portion and the twist at the twisted portion gathered later cancel each other out, it is possible to eliminate all or a part of the twist at the twisted portion, so that the linear body on the supply downstream side Is smoothly transferred to the next twist-entanglement operation, whereby the production efficiency of the three-dimensional structure can be dramatically improved.
