    摘要: 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.

    摘要: A helical winding unit is provided with a frame member in which a plurality of nozzle attachment units are provided to be aligned in a circumferential direction about an axis of a liner; nozzle units that each have a guide body movable in a radial direction of the liner and rotatable about a rotating axis extending in the radial direction, and that are attachable to and detachable from the nozzle attachment units; a moving endless toothed annular body that transmits, commonly to one or more nozzle units attached to one or more nozzle attachment units, power for moving the guide body in the radial direction; and a rotating endless toothed annular body that transmits, commonly to one or more nozzle units attached to one or more nozzle attachment units, power for rotating the guide body about the rotating axis.

    摘要: 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.
