A FW apparatus includes a bobbin driving unit, a winding device, and a tension applying device. A FW method using the FW apparatus includes a temporary suspending step of temporarily suspending operation of the winding device in the middle of winding the fed-out fiber portion around the workpiece. In the temporary suspending step, the length of the feeding path is increased by moving the pressing member while causing the pressing member to press against the fed-out fiber portion in a state of continuing to feed out the fed-out fiber portion from the fiber roll portion.

With regard to a filament winding device in which a plurality of fiber bundles are simultaneously wound around a liner, a tension detecting portion and a tension adjusting portion are miniaturized, the cost of the tension detecting portion and the tension adjusting portion is reduced, and the tension detecting portion and the tension adjusting portion are easily arranged. Provided is a filament winding device 100 that includes a tension adjusting portion 110 that collectively adjusts tension of a plurality of fiber bundles F unreeled from a plurality of bobbins B and an unreeling failure detecting portion 130 that individually detects the unreeling failure of the fiber bundles F on the bobbins B for each bobbin B.
