ある。 A centrifugal molding device inserts a mandrel wrapped with reinforcing fiber cloth in advance into a mold, and then rotates the mold at a predetermined speed to spread the reinforcing fiber cloth of the mandrel onto the inner peripheral surface of the mold. After the resin is rolled up, a resin liquid is supplied into the mold to perform the desired centrifugal molding. A problem in such a centrifugal molding apparatus is how to accurately transfer the reinforcing fiber cloth to the inner circumferential surface of the mold. This is because, if this is not done correctly, the reinforcing fiber cloth on the inner circumferential surface of the mold will become wavy, leading to deterioration in quality. However, in order to accurately transfer the reinforcing fiber cloth, it is necessary to firmly hold the reinforcing fiber cloth on the mandrel and to instantly release the reinforcing fiber cloth when the mold reaches a predetermined rotational speed.

In the gap with the mandrel 7, oil 13 is provided with seal members 10 and 11 to prevent leakage. is sealed under pressure. The reason for enclosing this oil 13 is to increase the lubrication effect by expanding the thin cylinder 12 under the pressure of the oil 13, and at the same time, machining can be omitted. An elastic plate 14 is wound around the outside of the cylindrical body 12 about half the circumference thereof. One end of the elastic plate 14 is movably attached to the cylindrical body 12 via a rubber plate 15, and the other end is slidably attached to the cylindrical body 12 via a guide plate 16. A pressing portion 1 is provided at one end of the elastic plate 14 and extends forward in a curved manner.
4A is formed. 17 is the pressing part 14A

The pressing portion 1 is formed on the outer periphery of the cylindrical body 12 within the elastic plate 14.
A movable member 18 disposed near the movable member 18 and capable of reciprocating in the axial direction, a cylinder 19 for reciprocating the movable member 18, and a plurality of cylinders 19 formed at appropriate intervals on the side of the movable member 18. It consists of inclined cam grooves 20, pins 21 that engage with these inclined cam grooves 20, and a connecting plate 22 that connects each pin 21 and the elastic plate 14. The working fluid is supplied to the cylinder 19 as follows.
That is, the ring body 9 is fitted externally and the stay 2
3, an annular groove 25 formed on the outer periphery of the ring body 9, a communication passage 26 and a communication pipe 27 that communicate the annular groove 25 with the cylinder 19; a recess 28 formed on the inner surface of the ring body 24 to face the annular groove 25;

ング体８，９が回転することにより解消される。 Before the winding is performed, the reinforcing fiber cloth 31 is previously wound around the mandrel 7 side. At this time, as shown in FIGS. 2 and 3, the movable member 18 is drawn toward the cylinder 19, and the cylinder 19 of the inclined cam groove 20
By positioning the pin 21 on the side, the pressing portion 14A of the elastic plate 14 is brought closer to the cylindrical body 12 side via the connecting plate 22. This approaching pressing part 1
4A, the reinforced fiber cloth 31 is pressed against the pressing portion 14A.
It is pressed and held on the free end 24a side by the elastic force of . In this state, the mold 1 is rotated, and when a predetermined rotational speed is reached, working fluid is supplied to the cylinder 19. As a result, the movable member 18 is moved away from the cylinder 19, and the inclined cam groove 20 moves to push up the pin 21 as shown by the imaginary line in FIG. As shown in FIG. 4, this movement of the pin 21 pushes up one end of the elastic plate 14, that is, the pressing part 14A, through the connecting plate 22, and the holding by the pressing part 14A is instantly released, and the reinforcing fibers The free end 31a of the cloth 31 hangs down and comes into contact with the molding surface 5. As a result, the free end 31
Frictional resistance is generated at a, and the reinforcing fiber cloth 31 is unwound from the mandrel 7 side and transferred onto the molding surface 5. At this time, a tensile force acts on the reinforcing fiber cloth 31, but this is eliminated by the rotation of both ring bodies 8 and 9 with respect to the mandrel 7.
