Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a penetrating knotless mesh having reinforcing mesh rows provided at required locations on the mesh.

(Prior art) Regarding the method of inserting reinforcing threads, see Utility Model Publication No. 12-1562, Japanese Patent No. 148179, and Japanese Patent Publication No. 62-56250 and Japanese Patent Publication No. 62-56251 by the present applicant.
Various methods have been proposed in Japanese Patent Publication No. 911, Japanese Patent Publication No. 6256252, etc.

(Problem to be solved by the invention) Proposed by the applicant (one person's 3 fl is nl
The purpose of these two cases is to solve various problems with knitted networks caused by the use of thick strands as reinforcing yarns.

Nowadays, it is possible to easily form reinforcing mesh rows at predetermined locations on a mesh fabric using the threads that make up the fabric, and the reinforcing strength can also be adjusted to suit the intended use of the fabric. It is desired that a penetrating knotless net be developed which is easy to use and inexpensive.

The present invention has been made in view of the above circumstances, and it is possible to easily form a reinforcing mesh row at a predetermined location of the mesh fabric using the threads that make up the mesh fabric, and the reinforcing strength also depends on the purpose of use of the fabric, etc. It is an object of the present invention to provide a penetrating knotless net that can be made appropriate according to the situation, is easy to construct as a WA construction, and is inexpensive.

[Means to solve the problem]

The method for manufacturing a penetrating knotless net of the present invention is to provide a penetrating knotless net J3 in which a net leg is constructed by twisting strands attached to a pair of weights, and the net leg is folded back at one edge. All the weights in the structure are roughened at at least 111 predetermined locations while traveling the entire width of the net fabric toward the other edge, then turn back at least one leg, and then advance toward the other edge again. After reaching the other edge, the weight advances the entire width of the screen to the one edge without turning back at the predetermined portion, and this is considered as one cycle, and all the weights repeat this. This feature is characterized in that a predetermined region of the net fabric has at least one reinforcing mesh row formed of one or more legs of two fabric constituent threads.

[For production]

According to the present invention, reinforcing mesh rows formed by two mesh fabric constituent yarns are formed in all 11 predetermined portions of the mesh fabric, and reinforcement W
JL] A through-type knotless net that can easily form rows, can be made suitable for the purpose of use of the reinforced strong electric net fabric, and is easy to manufacture and inexpensive.

〔Example〕

Hereinafter, practical Ik examples of the present invention will be explained with reference to FIGS. 1 to 5.

FIGS. 1 and 2 are schematic representations of an embodiment of the present invention. FIG. 3 shows the progress of one net leg in this embodiment. Each net leg in this embodiment is formed by twisting a land to a thread attached to a pair of weights, and as shown by the thick line in Fig. 3, each net leg in this embodiment is , After the knotting is completed at the predetermined part O while forming the net fabric in the left downward direction, the net legs turn around in the downward direction and go straight towards the left edge again, and at the left edge, it is the same as the conventional penetrating knotless net. Turn around and go straight to the right edge. At this time, each net leg reaches the right edge without turning back at the predetermined portion O like the above-described downward movement to the left, and here it turns back and becomes downward to the left as before. By repeating one cycle like this, the knotless network with the penetration of this embodiment is formed.

The progress of each net leg in this example becomes clearer when compared with the flow of the threads of a penetrating knotless net made of yarns made by twisting two strands of two trees as shown in FIG. That is, in the past, the upper solid line of the net leg 1 flows downward to the left, and when it reaches the left edge, turns back to downward to the right, and turns back at the right edge to flow downward to the left. The mesh leg 2 (broken line) and the mesh leg 3t (dotted chain line) are the same, and all threads follow similar trajectories to form a mesh.

Next, this embodiment will be described with reference to FIG.

Each of the net legs 1 to 7 is formed by twisting two strands, and the transition follows the trajectory shown in FIG.

That is, the net leg 1 moves downward from one part to the left, then turns downward to the right by three legs at the specific part O, and then moves downward to the left again toward the left edge. It turns back at this left edge and heads toward the right edge, but it continues straight to the right edge without turning back at specific point 0.

Similar to 1, the net legs 2, 3, 4, and 5 return to the three-leg analysis at the specific part L''IO on the left 1 and the gill, respectively, and head toward the left edge of the net.

The other net legs 6 and 7 that were folded back at the left edge are not folded back at a specific part and are folded back to the net legs 1.2, 3.4.5, etc.
It continues to move straight, intersecting with the others, forming a mesh.

As a result, a, b, c, d, e, f...
...and a reinforcing mesh row is formed.

Looking at mesh a in one row of these reinforcing nets, each of the mesh legs shown in Fig. 2 is formed by two mesh yarns made of yarns. The reinforcing mesh row by folding back three legs of is one stitch and a half width, and a
, b, c, d, e, f..., the mesh is reinforced in this order.

In the above embodiment, the folded part has three legs, but it goes without saying that if it is folded back with one leg, it will be reinforced by half a width, and if it is folded back with two legs, it will be reinforced with one stitch. On the other hand, if the number of folds is increased to four legs, it will be reinforced by 2 meshes and 1], and the number of reinforcing meshes can be easily selected and changed.

Furthermore, in Figures 1 and 3, the lower left net leg is turned back midway and the right lower net leg is moved straight forward, but a similar reinforcing net can be formed by moving in the opposite direction. .

In addition, Fig. 5 shows the progress trajectory of one mesh leg when two rows of reinforcing mesh rows of 1 and a half stitches are formed at a predetermined location in the mesh.
This is an example in which the lower left net legs are turned back by three legs at two specific parts O1P, and the right lower net legs go straight without turning back and move to the right edge.

By covering a plurality of folding points of the net legs as in this embodiment, a plurality of reinforcing mesh rows can be formed, and a reinforcing net suitable for the purpose of the net can be obtained.

Furthermore, as shown in the above embodiments, the penetrating knotless net of the present invention can form reinforcing mesh rows using the yarns that make up the net fabric, so it is easy to manufacture and inexpensive.

It should be noted that the present invention is not limited to the above embodiments, and can be modified as necessary.

〔Effect of the invention〕

As described above, according to the present invention, in contrast to the generally used knotless mesh fabric, it is possible to easily form two net fabrics at a predetermined location on the fabric using one or more mesh legs using the fabric constituent threads themselves. It is possible to knit the mesh while forming reinforcing mesh rows using common threads, and the number of reinforcing mesh rows can be easily reduced to 11, resulting in 1-minute strength depending on the purpose of use. It is possible to sharpen a net fabric having a thickness of 17 mm, and it also has advantages such as excellent productivity and low cost.
