Abstract: A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.

Abstract: A helical winding unit of a filament winding apparatus includes guide members guiding fiber bundles F to a liner, a movement mechanism moving the guide members, and a rotation mechanism rotating the guide members. Each of the guide members includes two side walls and guide portions fixed between the two side walls. As the guide portions, a first guide portion having a first guide surface and a second guide portion having a second guide surface and provided downstream of the first guide portion are provided. In the height direction, the first guide surface is oriented to one side. The second guide surface is oriented to the other side in the height direction and provided on the other side of the first guide surface.

Abstract: A filament winding device includes: a supporting unit that supports a mandrel on which a plurality of fiber bundles impregnated with a resin are wound, the supporting unit movable in the axial direction of the mandrel; and a helical unit having a plurality of fiber bundle guide units arranged radially in the circumferential direction of the mandrel and guide the corresponding plurality of fiber bundles to the mandrel, the helical unit supplying the plurality of fiber bundles to the mandrel through the fiber bundle guide units. Each of the fiber bundle guide units has a pressing roller for pressing a fiber bundle supplied to the mandrel, against the circumferential surface moving in the axial direction. The pressing roller can come into the contact with the circumferential surface of the mandrel and be rotationally driven about a roller axis extending in a roller axis direction perpendicular to the axial direction.
