Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fishing net knot structure and a striped method thereof, and more particularly to an improvement of a fishing net knot structure previously filed by the applicant.

The characteristics of the knotted structure of fishing nets previously filed by the applicant are as follows:
1. There is no misalignment.

2. The knot must be flat and not twisted.

3. High productivity with fewer wire mesh processes.

4. The amount of thread used for knotting is small and the yield of thread is good.

5. The nodules are small, so suspended matter in the water does not attach to them.
The amount of fish caught will be large.

However, this invention not only inherits the above-mentioned features, but also further improves the features of items 3 to 5 above, and adds a sixth feature of good convergence. The purpose is to provide fishing nets made of

In other words, when the fishing net is spread out, it can be easily converged, thereby increasing the efficiency of using the fishing net. The key point of this invention is that the knotted structure has the above-mentioned five characteristics, and that both the entry legs of the warp and weft of the knotted structure are sandwiched by the same two loops.
The knot structure and method thereof of the present invention will be explained below in accordance with the steps of weaving the net on a rope silk machine.

In Figures 1 to 13, 1 is the warp, 2 is the weft, and 3 is the warp.
4 is a top fishing rod, 4 is a thread swing, 5 is a comb, 6 is a lower piece, 8 is a cross beam, and each of the above-mentioned elements are normal ones, but 7 is an operation board that operates the weft thread 2. , this is a weft thread slip-off prevention device (Japanese Patent Application No. 1973-
No. 4727, Special Publication No. 56-20381, Special Publication No. 50-157284, and Publication No. 56-42700 of Tsubaki), and in addition to the function of a normal weft thread push-up board, it also has the function of preventing the weft thread from coming off. be. Figure 1 shows the preparation position, with the upper pot 3 facing the back of the paper, the thread swinger 4,
Both operation plates 7 are in the lowered position, and the warp threads 1 pass from the swinger 4 to the cross beam 8 and wrap around the already knitted silk, and the weft threads 2 come out of a boat-shaped box (not shown) and run along the slope of the operation plate 7. It rises, bends at the green above the control panel, passes through the comb 5, and becomes a lotus on the silk that has already been woven.

From this state, first, after the thread swing 4 is raised, the upper fishing 3 is moved to the fourth
The upper copper 3 rotates once in the direction of the rebound indicator when viewed from above (this is called reverse rotation, hereinafter referred to as this) until it reaches the position shown in the figure, and then stops. During this time, at the 1/4 rotation position shown in Fig. 2, the upper hook 3 moves the warp thread 1 from the right side of the upper hook 3 (looking at the upper hook 3 facing the line swing 4 side from the same direction, this will apply hereafter) to the left side. hang,
The thread swinger 4 descends near the pupil at 1/2 turn as shown in FIG. 3, and a loop lb is formed in the warp thread 1. After the upper piece 3 stops rotating, the operation plate 7 rises to push up the weft thread 2, as shown in FIG. Then, as shown in Figure 6, the upper copper is 1
The weft thread 2 is wound from the left side to the right side of the upper hook 3 around the 1/4 rotation position shown in FIG. After the upper hook 3 stops, the operating plate 7 descends as shown in FIG. 6, moves further toward the front, and the weft thread 2 is hooked onto the pot portion 7a of the operating plate 7. Next, the upper hook 3 rotates 3'4 times and stops, as shown in FIG. During this time, 1 shown in Figure 7
There is a time when the upper pot 3 faces the direction of the boat-shaped box of the weft thread 2 around /4 rotation, but the weft thread 2 does not come off because it is hooked on the hook portion 7a and pulled directly downward. And top fishing 3
After the rotation of has stopped, the operation plate 7 is moved toward the back of the paper to release the weft yarn 2 from the hook 7a, as shown in FIG. 8, and a loop lb is formed above the entry leg la of the warp yarn 1. The entry leg 2a of the weft thread 2 on the back side of the entry chest 11a
A loop 2b is formed above. Next, the lower copper 6 moves from right to left so as to pass through the loops lb and 2b, and in FIG. Then, the warp thread 1 of the thread swinger 4 is wound from the right side to the left side around the lower hook 6 that has stopped, and then the lower hook 6 is returned to the right in FIG. Pass through the boat-shaped box and receive the weft thread 2 from below. Next, as shown in FIG. loop lc and loops 2c and 2d of weft thread 2
is formed, and a withdrawal leg ld of the warp yarn 1 tightened in the loop 2d and a withdrawal leg 2e of the weft yarn 2 tightened in the loop lb and the loop 2b are also formed. When this knot is tightened and pulled out from the upper hook, a completed knot as shown in FIG. 12 is obtained. FIG. 13 shows the state in which the knot in FIG. 12 has been loosened to make the knot structure easier to understand. In this knot structure, the entry leg la is fastened by the loop lc, the entry leg 2a is fastened by the loop 2c, the exit leg ld is fastened by the loop 2d, and the exit leg 2e is fastened by the loops lb and 2b, so there is no misalignment. As shown in FIG. 12, the legs of the warp yarn 1 and the weft yarn 2 come out on the same side, so the silk is flat without any twisting, and as mentioned above, the number of knitting processes is lower than that of the present application. The amount of yarn used for knotting is smaller than that of the knotted structure of the previously applied fishing net, and not only is the knotted size itself small, but the loops lc and 2c are almost parallel, Since the legs la and leg 2a are both sandwiched between two parallel loops, the legs la and leg 2a have good convergence, and therefore the silk as a whole has good convergence. It has the advantage of making it easy to organize the silk and improving usage efficiency.

Note that the nodule structure may be bilaterally symmetrical as described above, and therefore, the nodule structure may be reversed from the above-mentioned method in terms of right and left and right and reverse.
