The upper side of Figure 1 shows the state in which the coil 36 is being wound around the rotary main body 13 before manufacturing the fiber-reinforced resin tube 6, and the lower side of the figure shows the state immediately after manufacturing the fiber-reinforced resin tube 6. The fiber-reinforced resin tubes 6 are manufactured alternately using two rotary main bodies 13. First, as shown in FIG. 8a, the coil 36 is connected to the reel 3.
5, the reel drive motor 29 rotates the housing 32 in the direction of arrow E. Then, the reel 35 is also rotated in the same direction, and the coil 3 wound around the reel 35 is rotated in the same direction.
6 is fed out from the feeding opening 33. As a result, the guide rod 37 at the tip of the coil 36 is aligned with the arrow D.
The coil 36 is wound around the rotary main body 13 while being guided by the guide rail 27. At this time, the tension motor 34 applies a rotational force in the direction of arrow F to the reel 35 to apply an appropriate tension to the coil 36.
6 to prevent it from coming loose. As above, the eighth
Once the coil 36 has been wound around the entire outer circumferential surface of the rotary body 13 as shown in FIG. bearing box 50
The support shaft 39 is held by the spindle 39, and the tape 63 is pulled out from the tape supply device 18 located at the left end in FIG. While rotating the mold body 13 in the direction of arrow F, the screw shaft 20
The tape supply device 18 is moved in the direction of arrow C by the rotation. As a result, the tape 63 is wound onto the coil 36. Next, after wrapping the tape 63, as shown in FIG. 8d, the glass fiber 2 is pulled out from the resin liquid-impregnated glass fiber supply device 19 located at the left end in FIG. Installation, drive shaft 11
As a result, the rotary main body 13 is rotated in the direction of arrow E, and the supply device 19 is moved in the direction of arrow C. As a result, the resin liquid-impregnated glass fiber 2 is wound around the ring 95 and the coil 36. Next, as shown in FIG. 8e, when the resin liquid 68 is cured and the tape 63 is integrated with the glass fiber 2 to form the fiber-reinforced resin pipe 6, the bearing device 15

6, the fiber-reinforced resin tube 6 is moved in the direction of arrow C and is pulled out from the rotary main body 13. At this time, the coil 36 is connected to the rotary main body 1
Since the coil 36 is wound along the tapered end portion of the fiber-reinforced resin tube 6, the coil 36 is smoothly peeled off from the inner circumferential surface of the fiber-reinforced resin tube 6. Note that since the tip of the rotary body 13 is bent to some extent, the fiber-reinforced resin tube 6 can be easily pulled out through the gap between the tip of the rotary body 13 and the support roller 54. The drawn-out fiber reinforced resin pipe 6 is placed on a lifting platform 59. Next, by removing the ring 95, the fiber-reinforced resin pipe 6 shown in FIG. 8f can be obtained.

In the first embodiment, the wide-diameter socket 6A is formed at one end of the fiber-reinforced resin pipe 6, but in addition to this, as shown in FIG. The first annular body 97 is externally fitted through the fiber reinforced resin tube 6, and then the fiber reinforced resin tube 6 is formed in the same manner as in the first embodiment. The body 98 is fitted onto the outside, and the resin liquid-impregnated glass fiber 2 is wound many times between the first and second annular bodies 97 and 98.
After curing, the fiber-reinforced resin tube 6 is pulled out from the rotary main body 13, and the first and second annular bodies 97, 98 are removed to form the fiber-reinforced resin tube 6 with a flange 99 shown in FIG. 9b. Good (Second Embodiment) Also, as shown in FIG. 10a, the rotary main body 13
The protrusions 100 are attached to appropriate locations on the upper coil 36 using double-sided tape, etc., and then the fiber-reinforced resin tube 6 is formed using the same procedure as in the first embodiment, and then the fiber-reinforced resin tube 6 is rotated. After pulling it out from the mold body 13, remove the protrusion 100 and open the hole 1 as shown in FIG. 10b.
A fiber-reinforced resin pipe 6 with 01 may be formed (third embodiment).

In addition, as shown in FIG.
By forming a fiber-reinforced resin pipe 6 in the same manner as in the embodiment, and then pulling out the fiber-reinforced resin pipe 6 from the rotary main body 13, a fiber-reinforced resin with a screw 102 is formed as shown in FIG. 11b. A tube 6 may also be formed (fourth embodiment).

Furthermore, the second embodiment shown in FIG. 9 may be modified to form a fiber-reinforced resin pipe 6 with a tube pillow (fifth embodiment).

Effects of the Invention As described above, according to the present invention, after forming a fiber-reinforced resin pipe, when the reel is rotated by the reel drive device to wind up a coil, the fiber-reinforced resin pipe is rotated. Since the coil is pulled out from the main body and is wound along the tapered end portion of the rotary main body, the coil can be smoothly peeled off from the inner circumferential surface of the fiber-reinforced resin tube. Therefore, the inner peripheral surface of the fiber-reinforced resin pipe will not be damaged.
