In FIG. 2, the notch a is not shown for the sake of clarity. The same applies to FIGS. 3 and 5.

Next, the manufacturing process of the penetration type knotless net by the braiding machine thus formed will be described.

First, the manufacturing process of the mesh leg will be described.

In this net leg, a pair of two weights 1 and 2, weights 3 and 4, weights 5 and 6, ... Then, each of the weights 1, 2, 3, 4, ... Of each of the net leg constituent units is revolved around the rotation axis of each of the carrier wheels A, B to form two pairs of weights of each net leg constituent unit. A total of two wound strands are twisted to form a net leg. In the present embodiment, the right-twisted net legs are formed by the forward rotation theory A, A ... And the left-twisted net legs are formed by the reverse rotation wheels B, B. The net leg portion above the assembled portion in FIG. 4 shows the net leg portion formed by the weights 1 and 2 and the weights 3 and 4.

Then, when the formation of the net legs having a predetermined leg length by each net leg constituent unit is completed, the braiding is continuously performed.

This braiding process will be described with reference to FIG. 3 showing an example.

FIG. 3 shows the weights 1, 2, arranged on the forward rotation wheel A and the reverse rotation wheel B.
Looking down at 3 and 4 obliquely from above, the forward wheel A and the reverse wheel B are 90
The operation state of each weight is shown in the order of steps from top to bottom with the state of being rotated once as a unit of process, and the strands drawn from each weight are represented by thick lines. And
At the intersection of the strands, the front strand is represented by a continuous thick line, and the back strand is represented by a broken thick line.

When performing the braiding according to the present embodiment, as shown in step (I) of FIG. 3, at the start of the braiding, the two wheels adjacent to each other in the continuous direction of the carrier wheels A and B (left and right direction in the figure) are adjacent to each other. Two net-leg constituent units (weights 1 and 2, 3 and 4 in the same figure) which are arranged on the carrying wheel, that is, the forward-wheel A and the reverse-wheel B, and which form the anti-twisted net legs, are formed in the assembly unit. As a result, we will carry out the following section.

Specifically, as shown in steps (I) to (X) of FIG. 3, the weights 1, 2, 3 of the assembly unit are combined with the progress of rotation of the forward rotation wheel A and the reverse rotation wheel B. , 4 are moved between two adjacent normal wheels A and reverse wheels B while intersecting each other. The crossing state of the weights 1, 2, 3, 4 is determined by the weights 1 and 2 and 3 and 4 which form the two net leg constituent units after the end of the assembly (step (X) in the figure). The relative positions of the wheels in the continuous direction (left-right direction in the figure) are interchanged. In other words, the weights 1 and 2 located on the left side of the weights 3 and 4 at the start of the assembly are located on the right side of the weights 3 and 4 at the end of the assembly. Furthermore, the crossing state of the weights 1, 2, 3, and 4 is determined by the weights 1 and 2 of the net leg constituent units arranged on the non-rotating wheel A at the start of the assembly.
2 is placed on the forward rotation wheel A even after the end of the assembly, and the weights 3 and 4 of the net leg constituent unit, which were placed on the reverse rotation wheel B at the start of the assembly, are also placed at the reverse rotation wheel B at the end of the assembly. ing.

The knotted portion in FIG. 4 shows the knotted portion knotted by the strands drawn from the weights 1, 2, 3, 4 according to the steps (I) to (X) in FIG. This braided portion is formed to be small, and each strand intersects with each other on average, so that the braided strength is also strong.

After the end of this assembly, the net legs are formed again by the respective net leg constituent units. In this case, since each net-leg constituent unit is arranged on the spindle wheel that rotates in the same direction before and after the knot, as shown in the net-leg below the knot in FIG. The weights 1 and 2 that had formed the right twisted net legs before formed the right twisted net legs even after the end of the knot, and formed the left twisted net legs before the start of the other knot. The weights 3 and 4 form a left-twisted net leg even after the assembly.

After the formation of the net legs, the weights 1 and 2 form a knot with the weights 7 and 8, and the weights 3 and 4 are one pair left from the weights 1 and 2 in the pair of normal rotation wheels adjacent to the left. Form a mass and a knot.

By repeating the net leg construction and the formation of the braid in this manner, the twist direction of the net leg composed of the two strands forming the penetrating braid as shown in FIG. A through-type knotless net is produced in which the right twist is constant and the left twist is constant as the left twist.

FIG. 5 shows a pair of weights 1 arranged on each of the wheel spindles A and B.
FIG. 4 shows the formation of the knots in the same manner as in FIG. 3 from step (I) to step (X) in the case of arranging Nos. 2, 3, and 4 in 180-degree phase. The braided portion formed according to the process shown in FIG. 5 is also formed in the same or substantially the same manner as the braided portion shown in FIG.

There are numerous steps in forming the braided portion according to the present invention, and FIGS. 3 and 5 exemplify some of them.

As described above, according to this embodiment, a total of four weights, one pair for each of the two normal wheels A and the reverse wheels B that are adjacent to each other in the continuous direction, are arranged to form an assembly unit. Therefore, as compared with the conventional example described in the above-mentioned publication, in the knotless netting machine, the distribution density of the weights with respect to the carrier wheels is twice as high. Therefore, according to the present invention, it is possible to produce double the number of 200-mesh nets by using the braiding machine which produces 100-mesh nets according to the conventional method. Therefore, it is possible to provide a knotless net with high capital productivity and low cost.
Also, when connecting nets to make a wide net, the number of sewn nets is half that of the conventional one, improving the efficiency of net-making work after knitting and reducing net-working work. Be converted.

The present invention is not limited to the above embodiment,
