ABSTRACT:
A filament winding apparatus that efficiently and orderly winds a fiber bundle with respect to a mandrel in a short period of time. A supporting board supports the mandrel, and a helical winding head supplies and guides the fiber bundle towards the mandrel. The helical winding head includes a group of guide tubes radially arranged on a circumferential surface of a guide ring, and a tube operation mechanism that reciprocates the guide tube along a tube axis center direction. The guide tube is moved closer to a circumferential surface of the dome part when the guide tube is facing a dome part of the mandrel such that the distance between the winding position of the fiber bundle and the guide tube at the dome part can be reduced, and the fiber bundle is orderly wound according to an appropriate winding trajectory.
