Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch line for long lines used for fishing large fish such as tuna.

[0002]

2. Description of the Related Art Branch ropes for long lines that have been conventionally used for fishing large fish such as tuna, that is, branch ropes attached to trunk ropes at appropriate intervals in the longitudinal direction are synthetic fibers such as nylon thread or It is known that three bundles of a large number of polyester yarns are twisted into three strands.

However, the branch line for long lines made by triple twist has a peculiar peculiarity to the twisted yarn, that is, a peculiar twist, and the specific gravity of the nylon yarn or the polyester yarn is larger than that of seawater, but is extremely large. Since there is no thread habit, there is a problem that the branch rope is entangled with the trunk rope,
There was a problem that the operability was poor because the long lines could not be thrown in and the work could not be rolled up smoothly. Furthermore, after pulling the long rope on the ship, it is difficult to remove the branch rope from the trunk rope due to the yarn habit of the branch rope, and after removing it, when storing it,
There was a problem that it was difficult to roll it up and store it.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve such problems, and to provide a longline branch rope that can be rolled up and stored when it is stored while eliminating the yarn peculiarity and improving the operability. That is the purpose.

[0005]

In order to solve this problem, the present invention comprises a core yarn made of fibers having a specific gravity of 2.00 or more, and wraps the core yarn with a covering yarn made of synthetic fiber. The gist of the present invention is that a plurality of yarns covered with this covering yarn is used for braiding.
Further, the gist of the present invention is that the fibers constituting the core yarn having a specific gravity of 2.00 or more are metal fibers. Further, the gist of the present invention is that the fibers constituting the core yarn having a specific gravity of 2.00 or more are synthetic fibers to which an adhesive resin containing metal powder is attached.

The present invention will be described in detail below. Fibers having a specific gravity of 2.00 or more that compose the core yarn means a metal wire having a specific gravity of 2.00 or more, such as a stainless wire or a tongue wire.
Examples include amorphous wires of various alloys. Alternatively, a synthetic fiber to which an adhesive resin such as urethane-based, acrylic-based, or nylon-based resin containing metal powder is attached may be used. The fibers having a specific gravity of 2.00 or more are used as a core yarn in a multifilament state.

[0007] As the synthetic fibers forming the covering yarn that wraps the core yarn, it is preferable to use multifilaments or monofilaments made of synthetic fibers such as nylon and polyester.

It is possible to produce a longline branch line by braiding a plurality of yarns coated with the above-mentioned coated yarn, but when making a tuna longline branch line, 8 or 12 pieces are made. This is preferable. In addition, it is possible to apply water repellent treatment to the braided rope, which can suppress the water content of the braided rope.

FIG. 1 shows a use state of a branch rope obtained by the present invention. In the figure, reference numeral 1 is a long rope for a long line installed near the sea surface. The long rope 1 for snapping is snapped at appropriate intervals in the length direction. A branch rope 3 is attached via a metal fitting 2.
Further, FIG. 2 shows a branch rope obtained by the present invention in cross section, 4 is a core yarn, 5 is a covering yarn for covering the core yarn 4, and the core yarn 4 is composed of a large number of bundles. And covered with the covering thread 5. Then, by using twelve yarns 6 formed by coating the core yarn 4 with the covering yarn 5, a branch line for a long line is produced.

As described above, since the branch rope for long lines of the present invention is manufactured by braiding, it does not have a yarn peculiarity as in the conventional branch rope for long lines made by the above-mentioned triple twist and is flexible. By using fibers with specificity and a specific gravity of 2.00 or more as core yarn, it is possible to improve the operability, because the sinking into the sea is quick and there is little trouble that branch lines are entangled with trunk lines. it can. Also, after pulling the long rope on the ship, the branch rope has no habit, so it can be easily removed from the trunk rope, and can be rolled up and stored when storing the branch rope.

[0011]

INDUSTRIAL APPLICABILITY As described above, the branch line for a longline of the present invention comprises a core yarn made of fibers having a specific gravity of 2.00 or more, and the core yarn is wrapped with a covering yarn made of synthetic fiber. Since it is braided by using a plurality of yarns covered with, there is no thread habit like the conventional branch rope for long line made by the conventional triple twist, and the sinking into the sea is quick, and the branch is There is little trouble that the rope is entangled with the trunk rope, and it is possible to improve operability. Also, after pulling the long rope on the ship, the branch rope has no habit, so it is easy to remove it from the trunk rope, and even when storing the branch rope, it can be rolled up and stored.
