Abstract
A filament winding apparatus includes a hoop winding unit that is configured to hoop wind a plurality of fiber bundles on an outer surface of a liner of a tank by rotating along a circumferential direction of the liner while moving back and forth along an axial direction of the liner. The hoop winding unit includes a fiber-bundle guide assembly that is configured to rotate along the circumferential direction of the liner during the moving back and forth of the hoop winding unit, and to guide the plurality of fiber bundles to the outer surface of the liner. The fiber-bundle guide assembly has a first fiber-turn section configured to change a moving direction of the plurality of fiber bundles from an approach direction to a turned direction perpendicular to the approach direction, wherein the plurality of fiber bundles are supplied to the fiber-bundle guide assembly in the approach direction with a state where the plurality of fiber bundles are arrayed in parallel with each other in a width direction perpendicular to the approach direction.
