The jacket structure of the core body 11 will be explained. That is,
Core metal body 111.1 is configured in a double cylindrical shape with an inner cylinder 17 and an outer cylinder 18 on the right, and these inner cylinder 17 and outer cylinder 18 are fixed to each other via a pin-shaped spacer 19. In addition, the jacket space 20 is secured and the strength of the core body 11 is maintained. Furthermore, heat transfer fins 18a are provided upright on the outer cylinder 18. Cooling water is flowed into the jacket space 20, and when the temperature rises due to the heat generated during hardening of the resin after wrapping the resin-impregnated II Iff band, pinholes are generated due to deterioration of the resin and gasification of the resin. etc. are prevented from occurring.

The core metal book 1 ho 11 includes a body core metal 21 and this body core metal 21.
A receptacle is detachably attached to both ends of the receptacle [1 part core bar 22 and socket part core bar 23 are shown on the right]. Specifically, a cylindrical body 24 for a J-receptor, which protrudes from the body core metal 21 in the axial direction, is fitted and fixed to both ends of the body core metal 21 by welding or the like.
Both claws (J cylinder body 24, socket part core bar 22 and socket part core bar 23)
and are removably fitted and fixed to the outside.

Figures 3a and 3b show the structure of the core bar 22 of the receiver 1. In other words, the socket core 22 has a jacket space 25 separate from the body core 21 (14 or this space 2).
A water outlet 2G, a water outlet 27, and a drain outlet 27 are formed. 28 is an annular plate made of 11 parts, and is fixed to the cylindrical body 24 at multiple positions in the circumferential direction. A clamp bracket 29 for clamping is installed.

is rotated slowly, and the resin-impregnated fiber band is spirally wound around it. When the resin hardens, cooling water is flowed into each of the sieve spaces 20, 25 and 41,
Prevents harmful humidity and upper back caused by heat generation of resin. Tree 1
Once the 1ft pipe 47 has hardened, the jacket space 20,
At the same time as stopping the water flow to 25.41, the rotation of the core body 11 is also stopped, and the resin tube 47 is pulled out from the core body 11 by pushing the end face of the resin tube 47 on the socket 45 side.

In addition to the above, as shown in FIG.
By attaching the socket core bar 22 to both ends of the resin pipe 47A, a resin pipe 47A having sockets 45 at both ends can be manufactured. In this case, in order to remove the resin pipe 47A from the core body 11, after molding the pipe 47A, handle one socket core 22 from the mounting cylinder 24, and then remove the other socket core 22 from the mounting cylinder 24. All you have to do is press the end face of the side socket 45.

On the other hand, by cutting the medium heat portion 48 of the resin pipe 47A formed in this manner, two short resin pipes 47B each having a socket 45 and an insertion port 46 can be manufactured at the same time. In addition, when forming a resin pipe by winding the resin pipe-impregnated MLFF band in a spiral shape, it is usually necessary to wrap it loosely at both ends, but as described above, it is possible to cut the short pipe 47B. When manufacturing two at the same time, the main pipe 4
Since one end of 7 [3 is not included, there is no need to wind up +13 on the side of the insertion port 4G, so it is possible to improve the yield.

FIG. 7 shows a case in which the socket core bar 23 is attached to both of the claw-attached cylinders 24. In this case, a resin pipe 47C having sockets 4G at both ends can be manufactured.
