Hold the spindle with the handles, pull out the tape from the tape supply device (to) located at the left end of Fig. 2, attach the tape end to the base end of the rotary main body (2), and then drive the tape. When the rotary main body (to) is rotated in the direction of arrow (j) by the shaft (b), the tape supply device (goods) is moved in the direction of arrow (c) by the rotation of the screw shaft (e). As a result, the tape is wound onto the carp/L'-.

Next, after wrapping the tape, as shown in FIG. 8(d), the glass fiber (2) is pulled out from the resin liquid-impregnated glass fiber supply device (6) located at the left end of FIG. Attach the end of the fiber (2) to the ring and attach it to the drive shaft (
b), the rotary body is moved in the direction of the arrow (q) by rotating the rotary body in the direction of the arrow (rotating it in the central direction and moving it to the above-mentioned feeding device). This causes the resin liquid-impregnated glass fibers (2) to flow into the ring and the coil A/-.

/- to the tip of the rotary body □□□, and the zero-order reel drive motor that supports the tip of the rotary body (2) moves the housing (to) in the direction of the arrow (G). Rotate. Then, the carp/L' (corporate) is wound up by the Lee/L/ (to), and the fiber-reinforced resin tube (6) is moved along with the carp/L'- in the direction of the arrow (G'). The rotary main body (2) is pulled out from the main body (2).
The tip of the fiber-reinforced resin tube (6) will bend to some extent.
is easily drawn out through the space between the tip of the rotary body □□□ and the support roller. The pulled out fiber-reinforced resin pipe (6) is a zero-order ring placed on the elevating joint.
When removed, the fiber-reinforced resin pipe (6) shown in Figure 8(f)
can be obtained.

Effects of the Invention As stated above (according to the present invention, after forming a fiber-reinforced resin tube, simply by winding the coil onto the reel using the reel drive device, the fiber-reinforced resin tube can be pulled out from the rotary main body together with the coil). There is no need to remove the rotary main body as in the past, which saves time and effort, and there is no need for a rotary mounting bed, which was required in the past. Since the pipe is drawn out indirectly through the carp, the fiber-reinforced resin pipe is not damaged.
