Bobbin 6 is unstable. In addition, since the outlet of the entangled thread 5 is located higher than the outlet of the shaft system 4, in order to prevent the bobbin 6 from catching the shaft system 4 during its movement, the shaft system 4 and the entangled thread 5 must be It has to be stretched upward at a nearly vertical angle, which increases the overall height of the device and requires a flattening process to push the twine 5 into the weave, making the manufacturing process and the structure of the device complicated. Become something.

Although it is possible to make the direction of the shaft system 4 and entangled thread 5 nearly horizontal by lengthening the gear rear shaft 3 upward, a large lateral force will be applied to the upper end of the bobbin 6, and the carry six ``The grip of the grip part 8 by the I! 117 tends to wobble, become stuck and become unstable.

The present invention was made in view of the above circumstances, and it is possible to stabilize the bobbin 6 by lowering the position of the draw-out opening for the entangled thread 5, and to make the drawing direction of the shaft system 4 and the entangled thread 5 close to horizontal. The object of the present invention is to provide a device that can make the entire device compact and eliminate the need for a reshaping process.

As a means for solving the problems, the present invention arranges a large number of points with two-dimensional expansion on a plane, and creates a large number of axis systems extending perpendicularly to the plane through each of the points, and This is a device for producing a three-dimensional fabric made of entwined threads that are entangled along arbitrary paths on the shaft group on a plane, in which a large number of carriers are arranged on a carrier fixing plate, and the center of the carrier is penetrated. The shaft system is inserted into a carrier shaft, and the bobbin on which the entangled yarn is wound is arranged between the carriers, and the carrier has a gripping means capable of gripping and releasing a gripping portion formed at the upper end of the bobbin. and the gripping means is rotatable at a predetermined angle about the carrier axis, the bobbin is gripped by the gripping means to rotate around the carrier at a predetermined angle, and the gripping means for the carrier is released. At the same time, by operating the gripping means of the adjacent carrier to transfer the bobbin to the adjacent carrier, the bobbin is fl-
The bobbin has an elliptical shape so that the bobbin can be moved along two paths, and a draw-out opening for the entangled thread is formed at the upper end of the central axis of the bobbin.

Operation Next, the present invention will be described in detail. In the present invention, the gripping part 8 is located at the upper end of the bobbin 6, and the drawer opening for the entangled thread 5 is formed at the upper end, and the thread storage part 9 is located below the gripping part 8. As a result, the pulling out position of the entangled thread 5 is close to the gripping position of the gripping part 8 by the carrier arm 7.

In addition, since there is nothing that protrudes greatly above the gripping position, the drawer 1 of the entangled thread 5 at the drawer opening of the shaft system 4 is at the same height, and the shaft system 4 and the entangled thread 5 are held at an angle close to horizontal. Even if it is pulled out, the bobbin 6 will not be caught by it.
