Abstract
A filament winding device includes a fiber bundle retainer that temporarily retains fiber bundles. The fiber bundle retainer includes: a reel member including an outer peripheral portion having pins movable in the axial direction relative to the fiber bundles supplied through fiber bundle guides and rotatable about the axis of the liner, the reel member capable of winding the fiber bundles onto the outer peripheral portion; a first cutting unit configured to cut a part of each of the fiber bundles in the circumferential direction, the part being between a part of the fiber bundle wound on the outer peripheral portion and a part of the fiber bundle wound on the liner; and a second cutting unit different from the first cutting unit and configured to cut a part of each of the fiber bundles in the axial direction, the part being wound on the outer peripheral portion.
