が偏肉になりやすい。 Conventional centrifugal molding equipment for obtaining the above-mentioned resin tube centrifugally molds a corrosion-resistant resin outer layer on the inner peripheral surface of a cylindrical mold, and then inserts a fiber on a shaft body inserted into the cylindrical mold onto the inner peripheral surface of the cylindrical mold. After that, the resin liquid was supplied into the cylindrical mold and centrifugally molded. According to such conventional configurations, in order to prevent the outer corrosion-resistant resin layer from being disturbed by the rolled-up fibers, the outer corrosion-resistant resin layer must be cured for a sufficient amount of time, resulting in large molding. I needed time. Furthermore, the fiber cannot be wound smoothly, and in particular, when the fiber is long, it is often wound in a wavy manner on the inner peripheral surface of the cylinder. Furthermore, since the winding start end and winding end of the fiber overlap, in the case of manufacturing a thin-walled resin tube, the overlapping part tends to have uneven thickness.

The present invention proposes a centrifugal molding apparatus comprising: the first resin liquid supply pipe opening near the annular bag and a cylindrical fiber housed within the cylindrical shaft. According to this structure, the fiber is not rolled up as in the conventional case, but is fed in a cylindrical shape along the inside of the corrosion-resistant resin outer layer, so that the corrosion-resistant resin outer layer is not sufficiently hardened. The fibers can be fed without any disturbance, and the fibers can be transferred smoothly and reliably, and the overall molding time can be shortened. In addition, since the fiber is cylindrical in advance, there are no polymerized parts.
Therefore, even if it is a thin-walled resin pipe, uneven thickness can be completely eliminated.
