。However, in a known centrifugal molding device, when centrifugally molding both ends of a hollow fiber bundle with a curable resin, (a) a curable resin liquid is applied from the outside into the mold at both ends of the rotating fiber bundle; It is not easy to supply the curable resin liquid to each end of each yarn bundle, or to supply the curable resin liquid at an appropriate time within the pot life. (b) In order to supply the curable resin liquid to both ends of the rotating yarn bundle in an appropriate amount and timing, centrifugal molding is necessary. The structure around the resin port 7 of the device is extremely complicated, and the resin liquid supply member (resin liquid pot, etc.) must be disassembled and cleaned, especially after centrifugal molding where the hardening resin has been solidified. The disadvantage was that it was difficult to do so.
