Description

[Detailed description of the invention] [Industrial application field] This invention is a fishing head strand wire mainly used for long line fishing and pole and line fishing for large fish such as tuna, more specifically, a cotton or chemically woven twisted yarn layer is provided around the outer periphery of the main wire. Concerning an improvement plan for wires.

[Conventional technology]

Among the conventionally known fishing strand wires,
There is something called "Tsumiyama Tsurimoto wire". As shown in Fig. 3, this wire has a main wire 2, which is made by twisting a plurality of galvanized metal wires 1, on the outer periphery of the wire to improve handling (mainly to eliminate slipperiness) and to prevent the main wire from rusting. For the purpose of strengthening the material, a layer (this is called a tsukiyama) of densely spirally wound cotton or chemically woven twisted yarn 3 is provided.

[Problem that the invention attempts to solve]

However, during production of this Tsukiyama Tsurimoto wire, the twisting and final twisting of the main wire strands and the winding pitch are equal to the diameter of the twisted yarn 3, so even if the work is mechanized, it is extremely time-consuming. It is necessary to go through three winding steps, which has the drawback of very poor productivity.

In addition, the twisted yarn 3 wound on the main wire has nothing to protect it, so it is easy to break due to friction or other causes.Furthermore, since it is protected on the main wire only by the winding tension, When the yarn breaks, the area near the cutting point where the tension is released is rewound several times (so-called unraveling), and as a result, there are many cases where the main wire is exposed due to the yarn breakage, which promotes deterioration of the rust prevention ability of the main wire. At the same time, it also has the disadvantage that it requires frequent rework to add broken threads and rewind them.

For this reason, recently, nylon-based wires and wires with a lead core inserted to promote sinking have been increasingly used as alternatives to the Tsukiyama fishing wire. In addition, it has new drawbacks such as being easily worn out and having a low specific gravity that makes it difficult to sink in water.

In addition, lead cored wire was developed as a solution to this drawback, but the lead core often breaks due to the difference in elongation between nylon and lead, so it has not achieved its original purpose. be.

The purpose of this invention is to solve these problems by improving the metal fishing rod wire.

[Means for solving problems]

The fishing strand wire of this invention which achieves the above object has a main wire 2 formed by twisting together a plurality of metal wires 1 whose surfaces are covered with a corrosion-resistant layer such as galvanized. There is a layer in which wires 4 and cotton or chemically woven twisted yarns 3 are alternately arranged and twisted in the circumferential direction, and each twisted yarn 3 of the layer is sandwiched between adjacent metal wires 4, 4. be.

In addition, in the illustrated fishing wire, the main wire 2 is 1
Since the cross-sectional configuration is ×7, six metal wires 4 were used. For example, in the case of a main wire with a cross-sectional configuration of 1 × (3 + 9), the number of outer layer strands is nine, so the metal wire 4 is used. The number of metal wires 4 used is made to match the number of outer layer strands of the main wire 2 in order to make the cross section of the base wire close to a perfect circle.

Each strand 1 of the main wire 2 may be one used in a general wire, but it may be a piano wire.
If the wire is GIS G 3522 B class or has a high tensile strength equivalent to this, a large tensile strength can be ensured with a small diameter wire.

The metal wire 4 is made of copper or stainless steel wire, which is hard to corrode.
Among them, a strong stainless steel wire is preferable. however,
If the corrosion resistance is increased by galvanizing, etc., inexpensive iron-based wires can be used, and even if non-ferrous metal wires other than those mentioned above are used, the effect obtained will be slightly different, but the present invention can achieve the purpose of

In addition, when selecting the metal wire 4, the main wire 2
Specifically, it is recommended to consider the material of the main wire, and specifically, to select a material that does not easily create a potential difference between it and the main wire. This is because the main wire 2 and metal wire 4 are
This is because, depending on the selection of materials, one of the two may become a sacrificial anode and be electrolytically corroded. As you can see, from the viewpoint of strength, it is preferable to use stainless steel wire as the metal wire 4, but depending on the material of the main wire, it may be more advantageous in terms of durability to choose another material. Sometimes.

The twisted threads 3 used have a thickness that protrudes outward from the adjacent metal wires 4 when twisted together.

In addition, coating the twisted layer of the metal wire 4 and the twisted thread 3 with a resin is also extremely effective as a measure to further enhance the rust prevention ability of the fishing wire.

Although the fishing wire shown in FIG. 2 is twisted in a S-Z combination, the direction in which the main wire 2 and its outer layer are twisted is not particularly limited. That is, S
-S, Z-Z twists in the same direction, and Z-S combinations in which the twist directions are opposite to those in the figure can also be adopted.

[Action/Effect]

According to this invention of configuring the fishing strand wire as described above, many effects and advantages listed below can be obtained.

The twisted yarn 3 ensures handling properties in terms of feel and slip prevention that are comparable to those of the Tsukiyama Tsurimoto wire shown in Figure 3, and furthermore, the twisted layer of the twisted yarn 3 and the metal wire 4 ensures The effect of enhancing rust prevention ability is ensured. In addition, it seems that the flexibility of the strand is deteriorated by adding the metal wire 4, but the increase in rigidity due to the wire 4 will be explained later.
This can be offset by the effect of the bending of the main wire.Also, in the conventional pile wire, the pile interferes with the bending of the main wire, but this invention does not have such a problem, and therefore, compared to the conventional pile wire, On the contrary, the flexibility is improved, and in that respect, it is also easier to handle.

The metal wire 4 and the twisted yarn 3 can be simultaneously and efficiently twisted together at a twisting pitch several times the strand diameter, resulting in very high productivity.

Since the twisted yarn 3 is held between the metal wires 4 that act as a binder along the entire length of the wire, there is no need to worry about it coming apart even if it breaks in the middle, preventing the main wire from being exposed, accelerating corrosion, and wasting time on rework. There will be nothing to spend.

The metal wire 4 prevents the twisted yarn 3 from being strongly crushed or subjected to strong frictional force when it hits the ship's edge, etc., and on the other hand, the twisted yarn 3 acts as a cushion layer when the metal wire 4 receives external force. Since the metal wire 4 and the twisted yarn 3 protect each other in this manner, breakage of both is reduced, and this also has the effect of preventing accelerated corrosion, thereby extending the product life.

Since the metal wire 4 receives part of the tension acting on the fishing wire, the tension resistance of the entire wire is strengthened.

Due to this effect, the wire diameter, which tends to be thick due to its structure, can be made 20 to 30% thinner than conventional Tsukiyama Tsurimoto wire, satisfying the various conditions required for Tsurimoto wire, and therefore improving fishing performance. . In addition,
It is well known that the thinner the wire, the easier it is for fish to hook into it.

Not only does the increased productivity reduce product costs, but it also extends the life of the product, making it economically advantageous.
