Method of producing tubular body |
摘要 |
A method of producing a tubular body wherein a continuous fiber impregnated with a resin is wound around a mandrel body rotating together with a mandrel shaft section at a predetermined circumferential speed while the continuous fiber is reciprocated in parallel with a rotation axis of the mandrel body, including moving a feed roller that feeds the continuous fiber to the mandrel body without rotating from a middle of the mandrel body to one end of the mandrel body; hooking the continuous fiber by a return section provided at the one end of the mandrel body; winding the continuous fiber on the one end of the mandrel body while a center axis of the feed roller is orthogonal to a feeding direction of the continuous fiber; and rotating the center axis of the feed roller to move the feed roller in a reverse direction. |

1. A method of producing a tubular body wherein a continuous fiber impregnated with a resin is wound around a mandrel body rotating together with a mandrel shaft section at a predetermined circumferential speed while the continuous fiber is reciprocated in parallel with a rotation axis of the mandrel body, comprising:
moving a feed roller that feeds the continuous fiber to the mandrel body without rotating from a middle of the mandrel body to one end of the mandrel body, hooking the continuous fiber by a return section provided at the one end of the mandrel body, winding the continuous fiber on the one end of the mandrel body while a center axis of the feed roller is orthogonal to a feeding direction of the continuous fiber, and rotating the center axis of the feed roller to move the feed roller in a reverse direction. |
