遊転ロールで押圧させることが考えられる。 Conventional centrifugal molding equipment has a configuration in which a reinforcing fiber cloth on a shaft inserted into a cylindrical mold is transferred onto the inner peripheral surface of the cylindrical mold, and then a resin liquid is supplied into the cylindrical mold to perform centrifugal molding. Ta. According to such a conventional structure, the reinforcing fiber cloth cannot be smoothly wound and is often wound in a wavy manner on the inner peripheral surface of the cylindrical shape. Furthermore, since the winding start end and the winding end end of the reinforcing fiber cloth overlap, in the case of manufacturing a thin-walled resin pipe, the overlapping part tends to have uneven thickness. Therefore, for example,
Using the format as seen in Publication No. 135024,
It is conceivable to supply a cylindrical reinforcing fiber cloth onto the inner circumferential surface of the cylindrical shape, and to press this reinforcing fiber cloth with an idle roll that can rotate and rotate freely.
しかし、このような形式によると、遊転ロール
