DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tapered fishing line suitable for "Tenkara fishing" using hair burr of mountain stream fishing and "Chikara" for throw fishing, and a method of manufacturing the same.

[0002]

2. Description of the Related Art In tenkara fishing using a hair burr of mountain stream fishing, a tapered fishing line is preferably used because the movement (action) of a fishing rod can be accurately transmitted to the hair burr. Also, in throwing fishing,
Tapered fishing lines are used because they can prevent the shock from being cut. By the way, in throw fishing, a tapered monofilament is often used as it is to catch a fish on the seabed. In Tenkara fishing and fly fishing, since it is necessary to accurately throw hair burrs at the target position, twist or assemble a tapered monofilament with a narrowed tip to obtain the effect of bending A frayed fishing line has been proposed (for example, Japanese Utility Model Laid-Open No. 5-43868). Another conventional tapered fishing line has been twisted or assembled using tapered filament fibers. For example, in the case of twisting, prepare a plurality of single yarns for the final required fishing line length in consideration of the amount of twist and shrinkage, apply the bottom twist / top twist, cut, tie the cut single yarn to other yarns, Was repeated to produce a tapered fishing line. In the case of assembling, all the filament fibers are formed into a tapered shape, or the core portion is formed by using a tapered filament fiber.

[0003]

However, in the method of twisting using, for example, seven tapered monofilaments, the twist habit remains, and the stability of twisting is not sufficient. Further, in the production of the tapered fishing line, there is a problem that at least a portion corresponding to the final required length of the fishing line in consideration of the amount of twist and shrinkage is required, and the appearance is inferior because a cut single line is tied. . On the other hand, in the method of assembling a tapered monofilament, it is necessary to prepare a plurality of tapered monofilaments while synchronizing a plurality of tapers, and in actual production, production costs are reduced due to complicated preparation. There was a problem that it became expensive.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, in which the manufacturing cost is low, the structure is stable against twisting, the appearance is high, the commercial value is high, and the form and physical properties are ensured even when used repeatedly. It is an object of the present invention to provide a tapered fishing line which is stable and has excellent durability and a method for producing the same.

[0005]

In order to achieve the above object, a fishing line of the present invention is a tapered fishing line assembled by a plurality of filament fibers, and a part of the plurality of filament fibers. characterized in that the diameter in the longitudinal direction of the fishing line by filament fibers reduce the number is cut filaments are small, and the cutting portion is incorporated into the length of 0.5cm~5.0cm as core yarn And Incorporation length of the cut portion into the core yarn
When it is less than 0.5cm, it is used repeatedly as fishing line
Durability tends to be insufficient, and 5.0 cm
If the length exceeds, the tapered shape is not good,
It tends to be disadvantageous in terms of cost.

In the above construction, the plurality of filament fibers are constituted by a plurality of sets of filament fibers each including two filament fibers, and the cut filament is one of the set of filament fibers. Is preferred.

In the above construction, the tapered fishing line
Is preferably assembled in a round string structure. Form
It is because it is excellent in nature.

In the above structure, the filament fibers are preferably at least one fiber selected from ultrahigh molecular weight polyethylene fibers, polyvinylidene fluoride fibers, polyamide fibers, and polyester fibers.

Next, a method of manufacturing a tapered fishing line according to the present invention is a method of manufacturing a tapered fishing line by assembling a plurality of filament fibers, wherein a part of the plurality of filament fibers is removed. The method is characterized in that the number of filaments is reduced by cutting, and the diameter in the length direction of the fishing line is reduced by incorporating the cut portion as a core yarn.

In the above construction, the filament fibers constituting the entire length of the fishing line and the spindle on which the bobbin around which the filament fibers to be cut are wound are connected, and are continuously connected to one track. It is preferable to configure

In the above construction, it is preferable that the filament fiber to be cut is incorporated as a core yarn into a length of 0.5 cm to 5.0 cm, and then cut. As a tissue (braiding machine) used in the present invention, a commonly used round braid machine is used.

The number of spindles on which the bobbin is mounted varies from 3 to 133.
Those with 12, 16, 24, 32, 48 spindles are particularly preferred.

In a method for producing a fishing line assembled from a plurality of filament fibers, before the filaments are sequentially cut and reduced in number to reduce the diameter, the filament fibers to be cut are incorporated as a core yarn and have a length of 0.1 mm. 5
Cut after braiding from 5.0 cm. This length is 0.
If the length is smaller than 5 cm, the durability of the fishing line when repeatedly used tends to be insufficient, and if it is longer than 5.0 cm, the tapered shape tends to be poor and the cost tends to be disadvantageous.

[0014]

According to the construction of the present invention described above, a plurality of filament fibers are assembled, and a part of the plurality of filament fibers is cut to reduce the number of filaments. Due to the small diameter and the cut part is incorporated as a core thread, it is low in cost, stable against twisting, has good appearance and high commercial value, and is suitable for repeated use. A tapered fishing line having stable physical properties and excellent durability can be realized. That is, a part of the filament fibers is cut along the length direction of the fishing line, and the diameter is reduced in the length direction of the fishing line by reducing the number of filaments, thereby forming a tapered fishing line. Also,
Since the cut portion is incorporated as a core yarn, the filament fibers in the cut portion do not protrude outside, and the form is stable and the appearance is good.

In the above, when the plurality of filament fibers are constituted by a plurality of sets of filament fibers including two sets of filament fibers, and the cut filament is one of the set of filament fibers, It is preferable because the braid structure of the thick part and the thin part is balanced, and the thick part and the thin part can be formed with the same structure.

In the above, if the cut portion of the filament fiber is incorporated as a core yarn with a length of 0.5 cm to 5.0 cm, the durability when repeatedly used as a fishing line is sufficient, and the tapered upper portion is formed. And it is also advantageous in terms of cost.

In the above, the filament fiber is
At least one fiber selected from ultrahigh molecular weight polyethylene fibers, polyvinylidene fluoride fibers, polyamide fibers, and polyester fibers can be preferably used as a tapered fishing line.

In the above, when the braided structure is a round string structure, the morphology is excellent. Next, according to the method of manufacturing a tapered fishing line of the present invention, when assembling a plurality of filament fibers and manufacturing a tapered fishing line, a part of the plurality of filament fibers is cut to reduce the number of filaments. In addition, the tapered fishing line of the present invention can be efficiently and rationally manufactured by reducing the manufacturing cost and reducing the diameter of the fishing line in the length direction by incorporating the cut portion as a core line.

In the above, the filament fibers constituting the entire length of the fishing line and the spindle on which the bobbin around which the filament fibers to be cut in the middle are wound are connected to form one track continuously. This is preferable because the braid structure of the thick part and the thin part is balanced, and the thick part and the thin part can be formed with the same structure.

In the above, the filament fiber to be cut is incorporated as a core yarn into a length of 0.5 cm to 5.0 cm, and then cut, the fishing line is sufficiently durable when repeatedly used and has a good tapered shape. It is also advantageous in terms of cost.

[0021]

The present invention will be described more specifically with reference to the following examples. (Embodiment 1) As a braid manufacturing apparatus for assembling a round braid structure according to an embodiment of the present invention, a known spindle round braid machine can be used. At the center of the pedestal, an 8-spindle round braiding machine with a hole through which the core yarn passes is used, and 100 deniers of ultra-high molecular weight polyethylene fibers (“Dyneema” manufactured by Toyobo Co., Ltd.) are prepared on four spindles. And 200 denier of the same fiber was prepared for the other four spindles. The 100-denier and 200-denier spindles were braided in a pair (one pair) and in the same orbit, a so-called chase method.

First, the braid was braided using all eight spindles, and was assembled to a length of 7 m. 20 at this stage
One denier yarn of 0 denier was cut and passed through a hole in the center of the pedestal, and this was used as a core yarn to assemble about 2 cm. Thereafter, the yarn was assembled 0.5 m, another 200-denier one-spindle yarn was cut, passed through a hole in the center of the pedestal, and used as a core yarn to assemble about 2 cm. After that, assemble 2m and do the same
The next 200 denier single spindle yarn was cut and passed through a hole in the center of the pedestal, and this was used as a core yarn to assemble about 2 cm.
Thereafter, 2 m was assembled, the next 200 denier single spindle yarn was cut, passed through a hole in the center of the pedestal, and used as a core yarn to assemble about 2 cm. Thereafter, 1.5 m was assembled. Thus, a fishing line was finally finished on a taper having a total length of 13 m. FIG. 1 shows a schematic model diagram of the obtained tapered fishing line. In FIG. 1, d indicates denier (yarn weight per 9000 m).

When this fishing line was used as a fishing line after throwing fishing and a casting line and used by a so-called angler, he was evaluated as having excellent flight performance and shock absorption. Received.

Further, it was confirmed that the braided yarn was not frayed and the durability was excellent even after repeated use. (Example 2) The same procedure as in Example 1 was carried out except that the fiber used was a polyvinylidene fluoride fibrous monofilament ("Fluoro Fighter EB" manufactured by Gohsen Co., Ltd.) 132 denier for all eight spindles. , FIG. 2
A tapered fishing line having a total length of 3.7 m was prepared.

This fishing line was evaluated by a fisherman, a so-called fishing master, as a tenkara bass (Japanese style fishing line), and was found to be excellent in flying performance and point-accuracy. And received the evaluation.

Further, it was confirmed that the braided yarn was not loosened even after repeated use and the durability was excellent. (Comparative Example 1) A plurality of filament fibers were assembled, the filaments were cut in the middle, and the number was reduced to reduce the diameter, thereby producing a tapered fishing line.

However, the tapered fishing line manufactured by this type of method has a poor appearance because the cut ends appear in a whisker-like manner, and the cut ends are unraveled by repeated use, and are entangled with other foreign substances. It was a cause of cutting and a drop in strength. For this reason, the durability was not sufficient.

[0028]

As described above, according to the present invention, the length of the fishing line is increased by assembling a plurality of filament fibers and cutting a part of the plurality of filament fibers to reduce the number of filaments. The diameter is reduced in the vertical direction, and the cut part is incorporated as a core thread, so it is low in cost, stable against twisting, good in appearance, high in commercial value, and suitable for repeated use. However, it is possible to realize a tapered fishing line having stable shape and physical properties and excellent durability. That is, a part of the filament fibers is cut along the length direction of the fishing line, and the diameter is reduced in the length direction of the fishing line by reducing the number of filaments, thereby forming a tapered fishing line. Further, since the cut portion is incorporated as a core yarn, the filament fibers of the cut portion do not protrude outside, and the form is stable and the appearance is good.

Next, according to the method for producing a tapered fishing line of the present invention, when assembling a plurality of filament fibers to produce a tapered fishing line, a part of the plurality of filament fibers is cut. While reducing the number of filaments, incorporating the cut part as a core yarn,
By reducing the diameter of the fishing line in the length direction, the manufacturing cost is low, and the tapered fishing line of the present invention can be efficiently and rationally manufactured.
