Abstract
(EN)
Provided is a cylindrical body manufacturing device having: a mandrel that rotates; a supply part that supplies a fiber-reinforced resin tape to the mandrel, said fiber-reinforced resin tape being obtained by impregnating a plurality of reinforcing fibers, which are oriented in one direction, with a resin composition; a fusion part that causes the supplied fiber-reinforced resin tape to fuse to the circumference of the mandrel; and a restraining member that restrains an end section of the supplied fiber-reinforced resin tape against a surface of the mandrel, and performs a rotating movement around the circumference of the mandrel integrally with the rotation of the mandrel.
