INSTRUCTION DESCRIPTION (1) Technical Field The present invention relates to a method of manufacturing a carcass constituting a fishing rod. [Technical Technique] The fishing rod used in fishing is composed of a narrow cylindrical body at the front end, and a plurality of carcasses are sequentially connected in a drawn form or a continuous form to form a fishing rod. In general, the fishing rod is produced by processing a material called a prepreg, which is a reinforcing fiber such as carbon fiber or glass fiber, into a sheet or a belt, and winding it on a core material to be fired. . Specifically, the prepreg is wound up to the cylindrical core material having a fine front end as needed, and the protective tape is spirally wound around the outer periphery thereof. Then, it was baked in a furnace, and the core material was taken out and subjected to surface treatment. In this manufacturing method, in order to increase the bending rigidity in the axial direction of the carcass, the prepreg material in which the reinforcing fibers are aligned in the axial direction is wound around the core material, and in order to increase the rigidity in the crushing direction, the reinforcing fiber is to be used. The prepreg material arranged in the circumferential direction is wound around its outer circumference. [Problem to be Solved by the Invention] However, when the fishing rod is manufactured in this manner, a convex portion made of a synthetic resin containing reinforcing fibers is formed on the surface of the carcass after the baking of the protective tape is removed. The convex portion is such that the longitudinal direction of the protective tape substantially coincides with the circumferential direction of the core material. As shown in Fig. 7, the reinforcing fibers 35 arranged in the circumferential direction of the core material enter the protective tape 20 together with the synthetic resin. The paper size of the stack is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) _一一~ -5- I---------Installation,--^--Ί---- ----Line, please read the notes on the back and then fill out this page} 1248785 Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printed A7 B7 _ five, the description of the structure of the invention section (2). The convex portion 40 thus produced may have a height of 0.025 to 0.030 depending on the thickness of the protective tape. In order to smooth the surface of the body, it is necessary to remove it by surface treatment after baking. However, since the reinforcing fibers 35 protrude into the convex portion 40, it is difficult to remove them by surface treatment such as honing. Therefore, conventionally, the concave and convex portions of the carcass are smoothed by applying a thick coating material to the surface of the carcass. An object of the present invention is to provide a method for producing a fishing rod body which is easy to smooth the surface. [Means for Solving the Problem] The method of the first aspect of the invention is a method for producing a fishing rod body constituting a fishing rod, comprising: a process of winding a first prepreg material around a core material, and a second prepreg material The process of winding to the outer periphery of the first prepreg and the process of spirally winding the protective tape to the outer periphery of the second prepreg in such a manner that a part thereof is repeatedly stacked. The reinforcing fibers included in the second prepreg are arranged in a direction crossing the long axis direction of the protective tape. In this method, the direction of the reinforcing fibers contained in the prepreg of the protective tape is intersected by the step formed by the stack of the protective tape and the direction of the reinforcing fibers. Therefore, the reinforcing fibers do not easily enter the step portion. Therefore, the convex portion generated on the surface of the body after firing is hardly containing reinforcing fibers. Thereby, it is possible to produce a carcass of a fishing rod which is easily smoothed by surface treatment such as honing. According to a second aspect of the invention, in the method of the first aspect, the reinforcing fibers included in the second prepreg are aligned in the axial direction of the core material. This paper size applies to the National Standard (CNS) Α4 specification (21GX297 mm) " (Please read the note on the back and fill out this page) Loading - Setting up -6- 1248785 A7 B7 Ministry of Economic Affairs Intellectual Property Bureau staff consumption Cooperative printing 5, invention description (3) In this method, the step portion generated with respect to the stack portion of the protective tape is substantially in the circumferential direction of the core material, and the prepreg material on the inner side of the protective tape The reinforcing fibers are arranged to be aligned in the axial direction of the core material. Because of this, the reinforcing fibers do not easily enter the stepped portion. Thereby, it is possible to manufacture a carcass of a fishing rod which is easily smoothed by surface treatment such as honing. [Embodiment of the Invention] (Structure of the entire fishing rod) As shown in Fig. 1, the fishing rod according to the first embodiment of the present invention has a tubular main body 1 and is sequentially connected to the main body in an extracted form. A plurality of cylindrical middle jaws 2, 3 on the front side of the crucible, and a front fine head 4 connected to the front side of the middle jaw 3. These carcasses are each composed of a prepreg material in which a synthetic resin is impregnated with reinforcing fibers such as carbon fibers or glass fibers. A tail plug portion 9 is detachably fitted to the base end portion of the main cymbal 1, and a reel seat 5 to which the reel is detachably attached is provided on the peripheral surface. On the front side peripheral surface of the reel base 5 of the main cymbal 1, a fishline introduction port 6 for guiding the fishing line from the reel to the inside of the cymbal body is formed, and on the circumferential surface thereof, a fishing line is guided to The fishing line of the fishing line introduction port 6 is introduced into the guide seat 7, and the fish body from the middle cymbal 2 to the front cymbal 4 becomes a line through which the fishing line is inserted, and the front end of the front shovel 4 is connected to the top. Guide 8. The fishing line from the reel is conveyed from the fishing line guide 6 through the fishing line guide 6 to the front side of the line, and is led out from the top guide 8 to the outside.

First, as shown in Fig. 2, a mandrel (core material) 100 having a thin rod shape at the tip end is prepared, and a release agent is applied to the peripheral surface as needed. Then, the pre-impregnated tape 10 processed into a belt shape is wound into the mandrel 1 螺旋 in a spiral shape without a gap. The prepreg is a structure in which a reinforcing fiber such as carbon fiber or glass fiber is aligned and impregnated with a synthetic resin such as an epoxy resin. The prepreg tape 1 〇 ' is arranged such that the reinforcing fibers are oriented in the longitudinal direction of the tape (the circumferential direction of the mandrel 丨00). Next, the sheet-like prepreg 11 is wound around the outer circumference of the prepreg tape 1 。. In the prepreg 11, the reinforcing fibers are arranged in the axial direction. Next, as shown in Fig. 3, a sheet-like prepreg 1 2 is wound around the outer periphery of the prepreg 11. The prepreg 12 has reinforcing fibers arranged in the circumferential direction. After winding the first prepreg material from the prepreg 1 〇 to the prepreg 1 2 to the mandrel 1 ,, as shown in Fig. 4, the flaky second prepreg 丨 3 is wound To the outer circumference of the prepreg material 12. The second prepreg 13 has reinforcing fibers arranged in the circumferential direction. Further, the second prepreg 13 is preferably a thickness of 〇 51 Ώ 1 Ή or less from the viewpoint of lightening the enamel body and facilitating surface treatment. Finally, as shown in Fig. 5, the protective tape 20 made of polypropylene or the like is spirally wound around the outer periphery of the second prepreg 13 in such a manner that a part thereof is repeatedly stacked. It is then calcined in a furnace to integrate the respective prepregs. Next, the mandrel 丨00 is taken out, and after the protective tape is peeled off, the both ends are cut into a desired length and then subjected to surface treatment.

INSTRUCTION OF THE INVENTION (5) By this manufacturing method, the reinforcing fibers of the pre-impregnated material after firing are stacked as shown in Fig. 6. The reinforcing fibers 3, 33 are arranged in the circumferential direction of the mandrel 100, and the reinforcing fibers 32, 34 are arranged in the axial direction of the mandrel 100. The protective tape 20 is spirally wound around the mandrel 100, so that the stepped portion 21 generated by the stacking portion of the protective tape 20 is substantially generated in the circumferential direction of the mandrel 100. On the other hand, the reinforcing fibers 34 included in the prepreg of the outermost layer on the inner side of the protective tape 20 are aligned in the axial direction of the mandrel 100. Therefore, the reinforcing fibers 34 do not easily enter the step portion 21, and the convex portion 40 generated on the surface of the body after firing is composed of only the resin layer containing almost no reinforcing fibers. Thereby, when the surface treatment is performed, the convex portion 40 can be easily honed and the surface can be easily smoothed. Thus, the thickness of the coating film which has been conventionally applied to smooth the surface to be smooth can be reduced. Alternatively, surface treatment such as polishing processing to increase the texture of the material may be performed without painting. On the other hand, when a metal thin film is formed on the surface of the ruthenium by a metal vapor deposition method such as ion plating, in order to make the gloss of the vapor-deposited metal thin film more beautiful, the surface of the ruthenium as the underlayer is mirror-finished. Conventionally, in order to facilitate mirroring, a treatment for forming a resin layer on the surface of the prepreg layer is performed. Further, in the carcass obtained by the method for producing a carcass of the present embodiment, since the surface can be easily smoothed, the surface of the calcined carcass can be easily mirrored. Therefore, it is possible to form a metal thin film having a beautiful luster without performing the treatment for forming the resin layer.

INSTRUCTION OF THE INVENTION (6) (a) In the above embodiment, the description is directed to the extraction type body, and is also applicable to the connection type body. (b) In the above embodiment, although the prepreg 10 to the prepreg 1 2 are wound inside as the first prepreg, the first prepreg is not provided. The number of times the prepreg is wound can also be increased or decreased. The prepreg material to be wound may be in the form of a sheet or a belt. [Effect of the Invention] In the method for producing a cartridge according to the present invention, the direction of the reinforcing fibers contained in the prepreg formed on the inner side of the protective tape and the inner side of the protective tape cross each other. Therefore, the reinforcing fibers do not easily enter the step portion. Thus, the convex portion generated on the surface of the carcass after firing is almost free of reinforcing fibers. Thereby, it is possible to manufacture a carcass of a fishing rod which is easily smoothed by surface treatment such as honing.
