The present invention relates to a rod constituting a rod, in particular, a method for producing a pole composed of a prepreg material made by impregnating a synthetic resin with a reinforcing fiber such as carbon fiber or glass fiber.

The rod of a fishing rod used for fishing generally winds the prepreg material processed into sheet shape and tape shape by impregnating synthetic resin, such as an epoxy resin, into the reinforcement fiber called prepreg, and baking this to a core material (燒成) is prepared. The pole manufactured by such a prepreg material is light and excellent in physical strength, and has fully exhibited the characteristic calculated | required by the fishing rod.

Among fishing rods made of such a rod, there is a type of fishing rod called a so-called middle fishing rod through which a fishing line is inserted into the rod. As such a rod for a medium barrel fishing rod, the thing which integrally formed the fishing line support protrusion continuously at the time of manufacture of a pole in the spiral form on the inner periphery surface of the fishing line passage inside a pole is often used. By forming the fishing line support protrusion on the pole inner circumferential surface in this way, the contact area between the fishing line passage surface and the fishing line is reduced, and the fishing line and the pole that are wet with water are prevented from sticking, and the sliding is performed. It also reduces resistance.

In the rod for the middle barrel fishing rod which provided the fishing line support protrusion in such an inside, a fixed diameter is needed in order to form the fishing line support protrusion, and a diameter must be made large compared with the case where a fishing line support protrusion is not formed. .

That is, in a fishing rod, it is small hardened toward the pole located in the waterline side, and it becomes easy to bend sequentially as it goes to the waterline side. In addition, it is preferable that the choke stick positioned at the most waterline side is made as small as possible to bend easily, and to react sensitively when the fish are prepared. However, in the case where the fishing line support protrusion is formed on the inner surface, the diameter of the pole is required as much as (the minimum diameter that the fishing line can insert) + (the height of the fishing line support protrusion), so that there is a limit to the small hardening.

Therefore, there has been a need for a method of manufacturing a pole, in particular a small diameter chord, which enables the fishing line to move smoothly in the rod without forming the fishing line support protrusion.

An object of the present invention is to provide a method capable of easily manufacturing a pole having a small diameter in which a fishing line can move smoothly in a pole.

The manufacturing method according to the first aspect of the present invention is a method of manufacturing a pole, which is a tapered ordinary body, which taper toward the waterline side constituting the fishing rod, and the outer periphery of the predetermined core material tapered to taper toward the waterline side. On the base end side of the core material, a step of winding the release tape in a spiral shape so that a portion is sequentially stacked and laminated, a step of winding the prepreg material around the outer circumference of the wound release tape, and firing the prepreg material in the furnace. Step to remove the core material, peel off the peeling tape, form a stepped tooth step on the inner circumferential surface of the prepreg material, and flow the water repellent paint into the inner circumference of the prepreg material decentered, It includes the step of applying while filling.

In this method, the predetermined peeling tape is wound on a core material while laminating a part thereof, so that the inclination and the step of the thickness of the peeling tape are formed on the outer circumference thereof sequentially. And when the prepreg raw material is wound around the outer periphery, the inclination and the step of the release tape are transferred to the prepreg raw material. When the core material and the peeling tape are peeled off after baking, the inclination and the step | step remain | survive on the cylindrical pole inner peripheral surface formed by the prepreg raw material, and the step | step is formed in the sawtooth shape which succeeds in particular. A water repellent paint adheres well by pouring a water repellent paint to the inner peripheral surface with such an inclination and a step, and filling it with a tooth-shaped step. In addition, the subtle inclination and the step of the inner circumferential surface of the pole reduce the contact area with the fishing line.

By forming a subtle inclination and a step | step in the inner peripheral surface by such a manufacturing method, a smooth movement of a fishing line is attained, without forming a fishing line support protrusion like the conventional one. And it can fully harden | cure small compared with the conventional pole.

In the manufacturing method according to the second aspect of the present invention, in the manufacturing method of the first aspect of the present invention, the release tape is a tape made of polypropylene having a width of 5 to 15 mm, and is formed on the outer circumference of the core material 1 to 3 It is wound in a spiral shape on the core while sequentially laminating a part of the proximal end of the tape at a pitch of mm.

By winding such a predetermined release tape on the core material, a good inclination and a step can be formed in the cylindrical pole inner peripheral surface.

EMBODIMENT OF THE INVENTION Hereinafter, one Example of this invention is described, referring drawings.

(Structure of the whole fishing rod)

As shown in Fig. 1, the fishing rod according to the first embodiment of the present invention includes a plurality of barrels connected to the cylindrical cylindrical rod 1 and the pulled side of the cylindrical rod 1 in a sequential order. It has a shaped bar 2, 3 (middle stripe), and a chocolate bar 4 connected to the waterline side of the bar 3. As described later, these circular bases 1 to choridae 4 are tapered tubular members that taper toward taper sides formed from prepreg sheets and prepreg tapes made of carbon fiber reinforced resins, glass fiber reinforced resins, and the like. to be.

The high end 9 is detachably fitted to the base end side of the far end 1, and the reel seat 5 which can attach | attach a reel detachably is provided in the circumferential surface. The fishing rod described in this embodiment is a so-called barrel fishing rod, and a fishing line inlet 6 for introducing a fishing line from the reel into the pole is formed on the waterline side circumferential surface of the reel seat 5 of the rod 1. A fishing line introduction guide 7 for guiding the fishing line into the fishing line introduction port is disposed on the circumferential surface thereof.

On the other hand, the top guide 8 is connected to the waterline side end of the chord 4, and the fishing line guided from the fishing line inlet 6 into the pole is sequentially sent to the waterline side to the outside from the top guide 8. Will be derived.

Moreover, in each of these poles, in the rod body (2; 元 上 竿) and the squadron (3) where a fishing line penetrates the inside of a pole, even if a spiral fishing line support protrusion is formed in the inner peripheral surface of the fishing line passage | route inside, good. This fishing line support protrusion can be formed by a well-known method. For example, the prepreg tape for forming a fishing line support protrusion is wound in a spiral shape to be integrally formed with the pole body.                     

(Structure and Manufacturing Method of the Glass Stand 4)

The small-size chocolate stand 4 located in the most waterline side of the rod is manufactured by a structure and a manufacturing method as described later, unlike the original bed 2 and the core 3.

As schematically shown in FIG. 2, the chord stand 4 is a cylindrical member tapered to the tapered side, and has a pole main body 10 having a subtle inclination and step on the inner circumferential surface, and an inner circumferential surface of the pole main body 10. It consists of the water repellent paint layer 11 laminated | stacked on. Although the structure of the pole main body 10 will be revealed in more detail by the manufacturing method mentioned later, carbon fiber reinforced resin which impregnated synthetic resins, such as an epoxy resin, in carbon fiber, and synthetic resins, such as an epoxy resin, in glass fiber A prepreg sheet and a prepreg tape made from impregnated glass fiber reinforced resin and the like are sequentially laminated, fired, and integrally formed. In this manufacturing process, subtle inclinations and steps of the inner circumferential surface are formed. It is preferable to set the inclination so that the waterline side to be concave becomes a gentle inclined surface, and the proximal end is in a steep inclination. This is because such incline does not inhibit the water that penetrates with the fishing line inside the pole from flowing out to the waterline.

On the other hand, after the pole body 10 is manufactured, the water repellent paint layer 11 is applied by a method such as pouring a water repellent paint into the cylindrical shape.

Next, the manufacturing method of the chopping board 4 is demonstrated sequentially.

As shown in FIG. 3, the cylindrical core material 50 (mandrel) which becomes thinner toward the waterline side with a predetermined taper is prepared, and this brother etc. are apply | coated to the peripheral surface as needed. And the peeling tape 51 made of polypropylene etc. is wound around the outer periphery. Although this peeling tape 51 depends on the magnitude | size of the chocolate stand 4 to manufacture, it is generally preferable to use about 5-15 mm in width and about 20 micrometers-30 micrometers in thickness. Then, the peeling tape 51 is partially overlapped with a pitch of about 2 mm sequentially from the base end side of the core material 50 (sequentially moving little by little in the axial direction of the core material 50 by 2 mm from the base end side). It is wound while laminating (see FIG. 4).

Next, as shown in FIG. 5, the outer circumference of the auxiliary prepreg 51 wound in this manner is joined to the outer circumference of the prepreg 51 without twisting, and then the prepreg material 52 impregnated with an epoxy resin or the like is sheeted. The thing processed into the shape or tape shape is wound up. Thus, the prepreg raw material 52 wound up comprises the pole main body 10 mentioned above, and you may wind up the several prepreg raw material 52 in multiple sheets. For example, the prepreg raw material 52 wound directly on the outer circumference of the release tape 51 is positioned at the innermost side, and the sheet in which the carbon fibers are joined without being twisted in the axial direction in order to improve the bending strength in the axial direction of the pole. It is preferable to use the prepreg raw material 52 of the shape. In order to increase the rigidity of the collapse direction, the tape-shaped prepreg material 52 in which carbon fibers or glass fibers are oriented in the longitudinal direction of the tape may be further wound on the outer circumference thereof.

By winding such a prepreg raw material 52 while applying pressure to the outer periphery of the peeling tape 51, it adheres as it flows in between the layers in which resin of the prepreg raw material 52 is laminated | stacked, and is shown in FIG. As described above, the inclination and the step of the release tape 51 are transferred to the inner circumferential surface of the layer composed of the prepreg raw material 52.

Thereafter, if necessary, the molding tape is wound around the outer circumference of the prepreg raw material 52, which is fired in the furnace to cure and integrate the prepreg raw material 52. Subsequently, the core material 50 is pulled out, the both ends are cut equally and adjusted to an appropriate length, the peeling tape 51 existing on the molding tape or the inner circumferential surface of the outer circumferential surface is peeled off, and the peripheral surface is polished and smoothed to prepare the chopping board 4. Manufacture. At this stage, the peeling tape 51 is peeled off from the inner circumferential surface, so that an inclination and a step are formed on the inner circumferential surface of the pole main body 10 formed by the prepreg raw material 52 (see Fig. 6 (a)). Here, the water repellent paint is poured into the inner circumference of the chord base 4 and attached to the inner circumferential surface to provide the water repellent paint layer 11 (see FIG. 6 (b)).

As for the chocolate stand 4 manufactured in this way, a subtle inclination and a step | step are formed in the inner peripheral surface of the pole main body 10, and a water-repellent coating adheres well by apply | coating a water repellent coating to this inner peripheral surface with such inclination and a step | step, The water repellent coating layer 11 can be easily formed. The subtle inclination and the step of the pole inner circumferential surface also reduce the contact area with the fishing line, while the water repellent paint layer 11 excludes water invading with the fishing line, without forming the fishing line support protrusion. The fishing line can be moved smoothly. And compared with the conventional pole, it can fully make small hardening and it becomes the fret board 4 of a sensitive reaction.

[Other Example]                     

(a) The pitch width, thickness, etc. of the peeling tape 51 can be set arbitrarily, and what is necessary is just to set according to the magnitude | size of the chocolate stand 4 to manufacture.

(b) In the said embodiment, although the said method is employ | adopted only in the chord stand 4 which especially requires small hardening, it is not limited only to a chord stand, It is of course also possible to apply to another pole.

According to the method of the present invention, it is possible to easily produce a pole having a small diameter in which the fishing line can move smoothly in the pole.
