Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for manufacturing a fishing rod. In particular, a through fishing rod forms a fishing line guide that protrudes inside, sprays spray, or forms fine irregularities to accumulate and hold a coated water repellent material or a material with good slipperiness. , Fishing line is on fishing rod surface,
In particular, the present invention relates to a method for forming irregularities on a fishing rod surface so as not to adhere to a wet surface.

[0002]

2. Description of the Related Art For example, in a through fishing rod, since the fishing line passes through the inside, prevention of increase in the line resistance is a fundamental problem, and contrivances such as providing an annular guide ring or a helical guide inside have been made. These are used to receive the fishing line and prevent the line resistance from increasing. In the outer fishing rod, a plurality of guide rings are provided on the outer circumference of the rod and are spaced apart in the longitudinal direction, and the fishing line is guided through the inside of these. In the manufacture of projecting and integrating a helical guide inside a fishing rod, generally, a heat-resistant tape having a thickness corresponding to the amount of protrusion is wound on a cored bar, and a guide forming element body is wound between the tape gaps. Then, a prepreg for forming a rod tube main body is wound therefrom and integrally formed by heating.

[0003]

However, if the size and shape of the tape interval deviate from predetermined values, the element body cannot be wound correctly, or the resin of the prepreg will not be able to guide the space between the tape and the guide during heating. The burrs are formed by spreading in the gap between the formed body and the formed guide, which results in damage to the fishing line and increases the line resistance. The heat-resistant tape is generally formed of a synthetic resin tape or the like made of a single material such as a fluororesin in consideration of mold releasability, etc., in which the rigidity is strong, it is difficult to wind around a small diameter portion, and If the waist is weakened, the elongation rate increases, so that when wound under tension, the cross-sectional shape is deformed, and the tape interval and the like deviate from a predetermined value. Further, when the tape is removed after the rod tube is formed, if the tape is cut off during the removal, it is difficult to remove the remaining tape.

Further, in view of cost and weight, if the pitch of the spiral guide or the interval between the annular guide rings is increased, or if the inner diameter is too small to form the projecting guide, the projecting guide is required. Instead of this, it is necessary to form fine irregularities on the inner surface of the rod pipe and store and retain a water-repellent material such as wax or a material with good slipperiness in this, thereby reducing the fishing line resistance. Want to manufacture easily. Also, in the outer fishing rod, if the interval between a plurality of guide rings arranged at intervals in the longitudinal direction on the outer periphery of the rod is too large, the fishing line hangs during this interval and comes into contact with the surface of the rod pipe. In particular, if the rod tube surface is wet with water, the fishing line adheres, and the fishing line cannot be released smoothly, which causes inconvenience.

Accordingly, the present invention provides a through fishing rod which can form a projecting fishing line guide with high precision for guiding a fishing line smoothly, and an externally passing fishing rod has unevenness on the surface of a rod pipe, and the fishing line is formed by these projections. It is an object of the present invention to provide a method of manufacturing a fishing rod capable of receiving and smoothly guiding a fishing line, and a method of easily forming minute irregularities on the inner surface of a rod pipe in a through fishing rod.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned object, according to the present invention, there is provided a rod-shaped tube produced by winding a prepreg obtained by impregnating or mixing a high-strength fiber with a resin. A tape having a layer of a flexible material and a reinforcing layer of a fiber aggregate having a smaller elasticity than the flexible material and integrated with the flexible material layer adjacent to the core, It is wound and arranged on an inner mold that includes gold, a fishing line guide element is wound around the space between the tapes, a prepreg for the main body is wound on the guide element and the tape, and heat-formed. And a method of manufacturing a fishing rod, wherein the tape is removed after molding. According to the second aspect, in the production in which the prepreg in which the resin is impregnated or mixed with the high-strength fiber is wound to form the rod tube by heating, the prepreg for the main body is wound to have durability against the heating temperature and flexibility. A tape in which a layer of a material and a reinforcing layer of a fiber aggregate smaller in elasticity than the flexible material are integrated adjacent to the flexible material layer is wound on the prepreg for the main body, and the tape interval is set. Winding the string-shaped element body in the space, providing an outer mold including a fastening tape and an outer mold on the string-shaped element body and the tape, heat-molding, and removing the integrated tape after molding. And a method of manufacturing a fishing rod characterized by the following.

According to a third aspect of the present invention, in the production of heating a rod tube by winding a prepreg obtained by impregnating or mixing a high-strength fiber with a resin, the rod has durability against the heating temperature,
A tape formed so as to have fine irregularities on at least one side thereof is wound on an inner mold having a core metal with the one side facing outward, and a prepreg for a main body is placed on the tape. And a method of manufacturing a fishing rod, wherein the tape is removed.

According to the first aspect, in the tape in which the layer of the flexible material and the reinforcing layer of the fiber assembly having small elasticity are integrated adjacent to the flexible material layer, the elongation is small due to the presence of the reinforcing layer. Nevertheless, since the reinforcing layer is a fiber aggregate, it has a low stiffness, can easily follow a small-diameter core, and can be wound with high accuracy. Further, due to the presence of the reinforcing layer, it is difficult to deform even when work is performed under tension, and the space between tapes can be formed with high accuracy. Therefore, the fishing line guide body is wound and arranged in this highly accurate space, heated and integrated with the main body prepreg,
Thereafter, if the integrated tape is removed, a fishing rod having a highly accurate fishing line guide can be formed. Since the integrated tape is reinforced by the reinforcing layer, it can be prevented from being broken at the time of removal, and the removal operation becomes smooth. The method according to claim 1 can be used not only for forming a fishing line guide on the inner surface of the rod tube but also for winding a body having other projections formed on the inner surface. In claim 2, an integrated tape having the same characteristics as above is wound on the prepreg for the main body, and a cord-like element is wound around the space between the tapes, and is heated and integrated with the prepreg for the main body. After that, if the integrated tape is removed, a fishing rod having a highly accurate uneven surface can be formed. Even if the surface is wet with water, the fishing line hardly adheres.

According to a third aspect of the present invention, a tape formed so as to have fine irregularities is wound so that the surface on the irregular side faces the outside facing the prepreg for the rod pipe main body, and the prepreg for the main body is wound from above the tape. Since the tape is removed after heat molding, corresponding fine irregularities are formed on the inner surface of the rod pipe, and a water-repellent material or a material with good slipperiness can be accumulated and held in these irregularities, and the fishing line can be guided smoothly. However, these minute irregularities can be molded together during rod tube heating molding, which is convenient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is a partial view of a tape 10 used in the method for manufacturing a fishing rod according to the present invention. The central portion 10K is a reinforcing layer, and the upper and lower layers 10K
J is a layer of a flexible material. The flexible material layer 10J may be on only one side. The flexible material is a natural rubber, a synthetic rubber-based elastomer, a thermoplastic resin, or the like, and has a property of withstanding a heat molding temperature. In order to remove after forming the rod pipe,
A material having good releasability is preferable, and fluorine rubber and silicone rubber are preferable. The reinforcing layer 10K is made of a fiber aggregate having a lower elasticity than such a flexible material. The constituent fibers have a diameter of about 30 microns or less, preferably 10 microns or less. These fine fibers or ultrafine fibers are collected in a bundle, woven, or non-woven form, and a flexible material is integrated on at least one side of the reinforcing layer into a thinner layer than the reinforcing layer to form the tape 10.

Specifically, natural fibers such as silk, inorganic fibers such as carbon fiber and glass fiber, and organic fibers such as polyester fiber and aramid fiber are used. The flexibility of the tape thus formed is less stiff and easier to bend than that formed of a flexible material over the entire thickness of the tape. Therefore, it is easy to wind a core metal having a small diameter and the like, and it is easy to wind accurately into a desired spiral shape or the like. Also,
Elongation of the tape 10 is less than that of a flexible material formed over the entire thickness of the tape. Therefore, even when the work is wound around a core metal or the like, even if it is strongly pulled, the elongation is small and the deformation is small.

Further, the layer of the flexible material is a layer of a natural rubber, a synthetic rubber-based elastomer, a thermoplastic resin, or the like, and a material having a property that can withstand the heat molding temperature is selected. A degree of deterioration is unavoidable. If the tape is formed only from the material of this layer, there is a possibility that the tape will be cut off during removal after heat molding. However, the tape used in the present application is provided with a reinforcing layer 10K. In particular, inorganic fibers are less deteriorated and have high strength.

FIG. 2 is a view for explaining a case where the through fishing rod is manufactured by the manufacturing method according to the present invention. Preferably, a release agent is applied to the surface of the cored bar 12 and a predetermined width is shown in FIG. The tape 10 is wound at a predetermined pitch. After winding a heat-resistant thin tape or sheet over the wound side edges of the tape or omitting the thin tape (sheet), a resin is applied to the carbon fiber bundle or the like in the space between the tape side edges. The impregnated fishing line guide body 14 is wound, and a prepreg 16 for a rod pipe main body is placed on the fishing line guide body 14 and the tape 10.
After that, heat-curing is performed while pressing with a tightening tape or a mold.

Thereafter, the pressurizing means is removed, the cored bar 12 is pulled out, and the end of the tape 10 is pulled and removed.
In this manufacturing operation, since the tape 10 has a low stiffness, a high strength, and a small elongation, it is easy to wind the tape 10 around the small metal core 12, and the dimensional accuracy of the tape interval is improved.
As a result, a spiral fishing line guide that can smoothly and accurately guide the fishing line can be easily formed. Generally, the reinforcing layer 10K
Is made of fine fibers, and thus is fluffy. During heat molding, the fishing line guide body 14 and the prepreg 16 for the main body are formed.
The resin melts and takes in the fluff, leaving the fluff on the surface of the fishing line guide and the inner surface of the rod tube body when the tape is removed. In this way, the surface portion of the fishing line guide or the inner surface of the rod pipe can be strengthened, and the wear resistance thereof can be improved.

If the pitch interval of such a spiral fishing line guide is too large, or if the interval of an annular fishing line guide of another form is too large, the fishing line may come into contact with the inner surface of the rod pipe between them. A device for reducing the fishing line resistance will be described below. In FIG. 3, a flexible material layer 10J 'is provided on one side of the reinforcing layer 10K', and one surface of the flexible material layer has minute irregularities. This is because the reinforcing layer 10K ′ is formed in a woven cloth shape, and if the layered body of the flexible material is pressed or melted and integrated with the reinforcing layer 10K ′, the substrate reinforcing layer 10K ′ is formed. And irregularities in accordance with the surface irregularities. These irregularities usually have a height of 10
Microns or less, preferably 0.1 to 7 microns. By winding such a minute uneven surface toward the main body prepreg, minute unevenness can be formed on the inner surface of the rod pipe.

If such minute irregularities are formed, a fluorine resin or the like is sprayed into the inside of the rod tube by spraying, and the fluorine resin or the like is held in the minute irregularities to impart water repellency to the inner surface of the rod tube or to use a fishing line. The effect of reducing the contact resistance can be maintained. In addition, any method of forming fine irregularities on the tape surface may be used, and the presence of the reinforcing layer 10K 'is not essential. For example, the reinforcing layer 10K' may be formed only of fluororubber.

FIG. 4 is a view for explaining a method of forming spiral ridges and valleys on the outer periphery of the rod tube of the outer fishing rod. A mold release agent is applied to the cored bar 12 and a prepreg 16 for the main body is placed thereon. It is wound on it, and is spirally wound at predetermined intervals using a tape 10 having the same characteristics as those used in the case of FIG. Of course, other tapes may be used. However, if the tape 10 is used, as described above, the waist is soft, the winding operation can be easily performed with high accuracy, and the interval dimension accuracy is improved. The string-shaped element body 24 is wound around the space between the tapes, and for example, the molds 20A and 20B which are divided into upper and lower parts are put on the string-like element bodies 24, and are heated and molded while being pressed. As in the case of FIG. 2, a thin tape or sheet may be provided over the space between the tapes around which the string-shaped element is wound, and then the string-shaped element may be wound. A fastening tape may be used instead of the mold.

After the heat molding, the mold is removed,
When the tape 10 and the cored bar 12 are removed, a spiral uneven strip having a desired size and shape can be formed on the surface of the rod tube, so that the fishing line does not come into contact with the surface of the rod tube, and only a point-like contact is required. Even if the rod tube is wet, the contact resistance of the fishing line can be reduced because the top of the ridge is not wet. For the width of the ridges of the uneven ridges,
The width of the concave stripe is set to 3 times or more, preferably 5 to 20 times. Also, the width of the concave stripe is 10 based on the height of the convex stripe.
It is set to be at least twice, preferably 15 to 50 times.

When the thickness of the rod pipe body prepreg 16 is sufficiently large with respect to the required strength, a part of the rod pipe body prepreg 16 is formed by pressurizing and heating without disposing the string-shaped element body 24. To form a projection instead of the string-like element 24. This is the same when a convex portion such as a fishing line guide is formed on the inner surface of the rod pipe.

[0020]

As apparent from the above description, according to the present invention, it is possible to form a projecting fishing line guide with high precision in which the fishing line is smoothly guided in the through fishing rod, and to form an irregularity on the surface of the rod pipe in the outer fishing rod. Is provided, a fishing rod capable of receiving the fishing line by these projections and guiding the fishing line smoothly can be provided. Further, in the case of the through fishing rod, minute irregularities can be easily formed on the inner surface of the rod pipe.
