PURPOSE:To make the dismounting of a rotating mold main body unnecessary and consequently save labor and time by a constitution wherein sprocket wheels are rotated by means of a plate driving device. CONSTITUTION:When respective messenger chains 109 are run through driving chains 113 in the direction indicated with the arrow G by actuating a plate driving device 42, respective plates 36 shift from the inside of a rotating mold main body 13 through a gap made between the tip part 13A of the rotating mold main body 13 and a housing 32 and make a U-turn to the outside of the rotating mold main body 13. In addition, during the U-turn, the first engaging part 36A of one plate 36 engages with the second engaging part 36B of the adjacent plate 36. Further, when a fiber reinforced resin tube 6 is formed after the plates 36 cover the whole outer peripheral surface of the rotating mold main body 13, the messenger chains 109 are run in the direction opposite to the direction indicated with the arrow G, resulting in shifting the plates 36 in the direction indicated with the arrow C and making the plates 36 a U-turn to the interior of the rotating mold main body 13 so as to pull the fiber reinforced resin tube 6 out of the rotating mold main body 13. |
