Description

Description: The present invention relates to a method for tailoring, for example, drift gill nets and stationary nets in the fishery industry.

As is well known, fishing nets hang down from the sea surface and extend as desired, as can be seen, for example, in the fixed nets shown in FIG.
o) Or the pushing force acts so strongly that the ropes will be torn and fall, and at the time of tailoring (extension), every fixed interval of the net must be tied to a thick support rope.

From the background described above, it is required on a global scale to reduce the troublesomeness of the work of attaching and detaching the net, retain the work place and the work time to the minimum necessary limit, and at the same time, recycle the materials and the like to save the labor.

If you capture the conventional uneconomical means from another side, the float (flo
main rope R of FIG. 7 equipped with at) and intermediate rope R ′
By connecting intermittently, another string is knotted so as to form an Sui circle or semi Sui circle, so-called 800 straps R ″
Therefore, it is inevitable to suspend the lateral side of the mesh on the rope R one by one, which causes a high cost of manufacturing 800 strings in the mesh. This also applies to a drift gill net (not shown) that does not require the main rope R, which is uneconomical.

It is an object of the present invention to provide means for eliminating the above-mentioned conventional defects easily.

Hereinafter, the method of the present invention will be described in detail with reference to Examples.

1 to 6 show a method of tailoring a fishing net according to the present invention and a mode of tailoring.

The implementation is of various thicknesses (3 m / mφ ~ 3 in the drift gill net).
The support rope 1 of 0 m / mφ) was used, but the 6 m / mφ support rope 1 arbitrarily selected will be described below.

FIG. 1 shows that the tailoring thread 4 is passed through the ears 3 of the net 2 and the arbitrary spacing S
It is the aspect figure which made the tailoring thread 4 project by. In practice, the diameter of the tailoring yarn 4 was 2 m / mφ, the arbitrary interval S was 23.6 cm, and the protruding length L of the tailoring yarn 4 was 5 cm. However, the protrusion length L has a close relationship with that of FIG. That is, it is necessary to determine the protrusion length L according to the slack length.

FIG. 2 is a view showing a mode in which the tailoring yarns 4 protruding at an arbitrary interval S are twisted 180 ° in the horizontal direction with the support rope 1 so as to form a ring shape. In this case, if a twist of 360 ° or more is applied, a stronger binding force can be obtained, but the most suitable 180 ° is adopted from the relationship with the working time, and the ring-shaped portion 4-
a was formed.

FIG. 3 is an aspect diagram in which the vicinity of the tailing yarn intersection 4-b inside the ring portion 4-a and the support rope 1 are temporarily fixed by winding one or more times with an adhesive material or an adhesive material 5. In practice, the special adhesive tape or adhesive material 5 is a special polyester tape in which polyester filaments are linearly arranged in a longitudinal direction on a biaxially stretched polyester film and an adhesive having strong seawater resistance is applied.
m / m width was used. Adhesive material or adhesive material means a material having adhesiveness or adhesiveness, and specifically includes adhesive tape, etc., but it is only necessary to select the most suitable one according to the intended use of the fishing net, in particular I don't.

FIG. 4 shows that both ends (4-c, 4-d) of the tailoring yarn are pulled simultaneously or alternately with the tailing yarn crossing point 4-b of the ring-shaped portion 4-a as a fulcrum to shrink the leg-shaped portion 4-a. FIG. 3 is a mode view in which the adhesive material or the adhesive material 5 is closely attached. In practice, one end 4-d of the tailoring yarn 4 is adjusted by intuition or a scale so that the sagging length of the presser l becomes uniform with the tailing yarn intersection 4-b as a fulcrum.
Was strongly pulled in the direction of the horizontal axis and fixed in a tensioned state.

FIG. 5 shows that both ends (4-) of the tailing yarn are held while pressing the tailing yarn intersection 4-b of the annular portion 4-a in claim 2 of the claims.
c, 4-d) are simultaneously or alternately pulled, and the state of FIG. 4 is further pulled until the adhesive material or the adhesive material 5 undergoes plastic deformation.

By plastically deforming the adhesive material or the adhesive material 5, the ends of the adhesive material or the adhesive material 5 are less likely to peel off, and at the same time, both end portions of the adhesive material or the adhesive material 5 perpendicular to the support rope 1 are pulled and stable tension is obtained. Since the state is brought into a state, the binding portion is tightly tightened, the shift between the support rope 1 and the adhesive material or the adhesive material 5 is prevented, and the binding force of the tailoring yarn 4 can be increased. Although this method was adopted in the implementation, when trial was performed at a water depth of 10 m with a tailoring width of 20 m, no peeling or slippage occurred even in an underwater test for 6 months, and the above-mentioned effects were witnessed. .

Support rope 1. And tailor thread 4. When the adhesive or the adhesive is fixed, it is pulled more strongly to plastically deform the adhesive or the adhesive to prevent the end of the adhesive or the adhesive from peeling off, and at the same time, it is perpendicular to the support rope 1 of the adhesive or the adhesive. Since both end portions are pulled to be in a tense state, the binding portion is tightly tightened, the shift between the support rope 1 and the adhesive material or the adhesive material can be prevented, and the fixing force can be further increased.
