本発明は釣竿の製造法、詳しくは、高強度繊維に合成樹
脂を含浸したプリプレグ（１）を巻回してなる釣竿の製
造法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a fishing rod, and more particularly, to a method for manufacturing a fishing rod formed by winding a prepreg (1) made of high-strength fiber impregnated with a synthetic resin.
（従来の技術）
従来、此種製造法として、特開昭４８−９０８７６号公
報に見られるように、高強度繊維に合成樹脂を含浸した
プリプレグを芯金に巻回して竿本体を形成し、この竿本
体の外周に熱収縮チューブを套嵌し、焼成して釣竿を製
造するようにしたものが提案されている。(Prior Art) Conventionally, as a manufacturing method of this kind, as seen in Japanese Patent Application Laid-Open No. 48-90876, a prepreg made of high-strength fiber impregnated with a synthetic resin is wound around a core metal to form a rod body. It has been proposed to manufacture a fishing rod by fitting a heat-shrinkable tube around the outer periphery of the rod body and firing it.
（発明が解決しようとする課Ｍ）
所が、この従来の製造法の場合、プリプレグを巻回して
成る竿本体は、その外周に套嵌した熱収縮チューブの熱
収縮力で緊縛させるだけであるから、緊縛力が不足して
竿本体の内部或いは竿本体と芯金との間に含まれている
多数の気泡の抜けが悪くて多くの気泡が残ることになる
のであり、このため、加熱焼成後、竿本体の内部に多数
の空調ができ、強度低下を来す問題があった。(Problem M to be solved by the invention) However, in the case of this conventional manufacturing method, the rod body formed by winding prepreg is simply bound by the heat shrinking force of the heat shrink tube fitted around the outer periphery. Because of this, the binding force is insufficient and the large number of air bubbles contained inside the rod body or between the rod body and the core metal cannot be removed easily, leaving many air bubbles behind. After that, there was a problem that many air conditioners were installed inside the rod body, which caused a decrease in strength.
本発明は以上の問題点に鑑み発明したもので、目的は、
熱収縮チューブを用いて表面の滑らかな釣竿を製造する
ことができながら、竿本体を充分に緊縛することが出来
て、高強度の釣竿を要造することが出来るようにするも
のである。The present invention was invented in view of the above problems, and its purpose is to:
To manufacture a fishing rod with a smooth surface by using a heat-shrinkable tube, while also being able to sufficiently tighten the rod body, and to manufacture a high-strength fishing rod.

Then, a reinforcing tape (3) made of high-strength fibers impregnated with synthetic resin is spirally wound with a tensile force that provides the necessary binding force to the rod body (2) so that the edges in the width direction are almost in close contact with each other. A heat shrink tube (4) was fitted around the outer periphery of this reinforcing tape (3) and fired.

In addition, since the heat shrink tube (4) is fitted around the outer periphery of the reinforcing tape (3) and fired, the rod body (2) and the reinforcing tape (3) are heated and fired. Even if the synthetic resin melts, this molten synthetic resin can be prevented from flowing out to the outside, allowing it to be molded to a predetermined thickness, and the surface can be made smooth.

して所定肉厚の釣竿を製造するのである。(Example) The prepreg (1), which is made by impregnating a synthetic resin in an aligned sheet of high-strength fibers such as carbon fibers, is used as a core metal (A).
A reinforcing tape (made of high-strength fiber impregnated with synthetic resin) is wrapped around the outer periphery of the rod body (2) to form a rod body (2).
3) to obtain the necessary binding force for the rod body (2).
The rod body (2) is sufficiently tied up by winding it spirally with a tensile force of ~10 kg so that the edges in the width direction are almost in close contact with each other, and a synthetic resin heat shrink tube is wrapped around the outer periphery of this reinforcing tape (3). (4) and fired in a heating furnace. Through this firing, the heat shrink tube (4) is heat-shrinked to bind the reinforcing tape (3), and the reinforcing tape (3) and the rod body are In (2), the synthetic resin is prevented from moving during firing, and the reinforcing tape (3) and the rod body (2) are integrally bonded to manufacture a fishing rod with a predetermined wall thickness.

のない釣竿を製造することが出来るのである。That is, using a prepreg (1), a reinforcing tape (3), and a heat shrink tube (4), the prepreg (1) is bonded to a core metal (
The reinforcing tape (3) bears the binding of the rod body (2) formed by winding around A), and the reinforcing tape (3) is
By winding with a tensile force of 10 kg, the rod body (2)
Air bubbles contained inside the rod body or between the rod body and the core metal are removed.Therefore, it is possible to manufacture a fishing rod without any cavities inside the fired rod body (2).

を滑らかにするのである。In addition, by winding the reinforcing tape (3) so that the edges in the width direction are almost in close contact with each other so that there is no gap between the edges in the width direction of the reinforcing tape (3), it is possible to prevent the rod from forming during firing. This prevents the synthetic resin in the main body from protruding outward from between the edges of the reinforcing tape (3) in the width direction, and makes the surface of the reinforcing tape (3) smooth.

を製造出来るのである。In addition, the prepreg (1) and the reinforcing tape (3) are made of thermosetting synthetic resin such as phenol resin, as in the past, but this synthetic resin melts when hardened by the baking process, reducing the viscosity. Since the synthetic resin becomes lower and moves, the reinforcing tape (3) is tightened by the heat shrinkage of the heat shrink tube (4) to prevent the synthetic resin from moving. Therefore, it is possible to manufacture a fishing rod with a predetermined wall thickness and a smooth surface.

仕上げ加工が行い易いのである。Further, although the heat shrink tube (4) is peeled off after firing, it may be left in place without being peeled off. In addition, in the case of peeling, the reinforcing tape (3) is wound so that its edges in the width direction are almost tightly wound, and there is little protrusion onto the surface of the synthetic resin, so finishing processing by polishing the surface is not possible. It's easy to do.
尚、前記熱収縮チューブ（４）はポリエチレンで形成す

てもよいのである。Although the heat shrink tube (4) is made of polyethylene, it may be made of other materials, such as polypropylene.

This makes it possible to manufacture smooth fishing rods.
