Description

[Detailed description of the invention] The present invention relates to a method for forming knots fff4 in fishing nets.

Conventionally, gillnets and other fishing nets made of monofilament have been formed using a double frog knot formation method (see Figure 15 +r<<); however, strong tension When applied to the ground, since the weft threads 12 are entwined with the loops of the warp threads 11 in a straight manner, the weft threads 12 turn (see Figure 1 O), and the weft threads move against the warp threads 11 at the knot. 12 moves, causing misalignment and breakage, which then spreads along the warp yarns 11 to the entire net.

In view of the above, the object of the present invention is to provide a knot forming method that allows the weft yarn to be entwined with the warp yarn (see Figure 73) to knit a net fabric in which no misalignment occurs and the net foot spreads completely in all directions. do.

The gist of this invention is b) Hang the warp threads onto the winding pieces.

Tip) Turn the winding piece 1/2 turn and hang the weft yarn from the opposite direction of the warp yarn.

c) Return the winding piece by 1/2 turn and hang the warp threads in the same direction as in item n11 a).

2) Turn the winding piece again by 1/2 turn in the same direction as in the above step) to remove the weft thread from the winding piece.

e) A fishing net knot forming method in which the winding piece is returned 1/2 turn again, the warp thread is pulled out through the loop of the warp thread at 1-, the weft thread is penetrated, and the weft thread is passed through the loop of the warp thread. be.

The method of this invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 11.

Nao, Figures 1 to 72 sequentially explain the 1st to 7.2 steps in the knotting process of the cycle. In each figure, t1 is 7'j warp thread, 2 is weft thread, 6 is vertical movement, left and right movement. dynamic and i
tl backward movement backward movement 1 repulsion lii intersecting, 4 is a movement that can move up and down.
5 is a comb fixed to a frame (not shown), 6 is a winding piece that can be rotated and tilted in an upright position, 7 is a lower hook that can be moved back and forth, 8 is a movable mold, and 9 is a movable mold. It is a Bunsen coin stored in 8.

@/Process (see Figure 1) With the hook 6A of the winding piece 6 stopped at a predetermined position facing toward the swinger 3, the warp thread 1 is moved from the swinger 3 to the lii
5, and the weft thread 2 is directed from the lifting plate 4 to the comb 5.

2nd step (see Figure 2) Raise the thread swinger 3 slightly above the hook part 6A and
from left to right on the hook part 6A.

Step 2 @ 3 (See Figure 3) Lower the thread swing 6 to lower the warp to the hook 6A, and move the winding piece 6 to the left 7172 times, and then move the lifting plate 4
3rd degree step (see Fig. 7) to slightly above the hook part 6A, J-, da1. 2 on the hook portion 6A.

Fifth step (see Fig. 5) Move the thread swinger 3 slightly above the hook portion 6A again, and hang the warp threads 1 from the left side to the right side of the hook portion 6A.

6th step (see Figure 2) Lower the thread swinger 3 to hang the warp on the C hook 6A, and then rotate the winding piece 6 to the left slightly more than 1/2 turn.

7th step (see Figure 7) The lifting plate 4 is lowered to remove the weft yarn 2 from the hook 1; 6A of the winding piece 6 and entangle it with the warp yarn 1.

Gth step (see Fig. g) The winding spool 6 is rotated to the right again slightly over 172 revolutions.

Step (see Fig. 9) After inserting the hook portion 6A and hooking the warp threads with the lower hook 7, insert the lower hook 7 backward.

70th step (see Figure 70) After retracting the lower hook 7 to the specified position ff'ffi, remove the hooked warp threads 1 and press J! Thread the continuous weft thread from Bunsen 9 of LLS8.

1st/Step (See 1st/Figure) The weft thread 2 is passed through the loop of the warp thread 11 by the warp thread 1.

Seventy-second step (see Figure 7.2) When the winding piece 6 is tilted to remove the knot ring formed by the warp yarn 1 and the weft yarn 2 entangled therefrom from the hook portion 6A, the seventh
As shown in FIG. 3, the weft yarn 2 is entwined with the warp yarn 102 loops, and a knot is formed which passes through nine loops of the 2/L/- loops.

Thereafter, this knot 11j is tightened by a tightening device (not shown) as shown in FIG. 1, and the cycle knot forming process is completed, and the warp yarns 1 and weft yarns 2 return to the state shown in FIG. 1, Thereafter, the knotting process consisting of steps 1 to 2 of Section 2 is repeated.

As described above, the method of the present invention is different from the conventional knot forming process, in that the weft yarns are entwined with the 2/L/- loops of the warp yarns, and are inserted through the loops of the 2/I/- loops. .

For this reason, there is no shift of the blind eye compared to the conventional double frog knot, and the net legs are completely spread out in all directions, making it a strong fishing rod.
Being able to knit a net can be effective.
