Abstract: In a filament winding apparatus, a supplying device supplies fiber bundles to a surface of a core material. A moving part is movable relative to the core material, and rotatable around a rotational axis extending in a vertical direction. A small diameter aligning guide part is placed at the moving part and has an opening portion through which the core material can pass. The small diameter aligning guide part guides fiber bundles to an outer peripheral surface of the core material such that the fiber bundles are arranged side by side in a circumferential direction of the core material. The tightening fiber bobbin supporting part is placed at the moving part and rotates around a center of the opening portion. A winding guide rotates with the tightening fiber bobbin supporting part and guides a tightening fiber bundle drawn from a tightening fiber bobbin toward the surface of the core material.

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.
