1. A filament winding method using a filament winding apparatus, wherein the filament winding apparatus comprises:
a bobbin driving unit configured to rotate a bobbin member including a bobbin and a fiber roll portion formed by winding a fiber bundle around the bobbin;
a winding device configured to wind a fed-out fiber portion fed out from the fiber roll portion around a workpiece in a state in which tension is applied to the fed-out fiber portion; and
a tension applying device provided in a feeding path of the fed-out fiber portion from the bobbin driving unit to the winding device, the tension applying device including a pressing member configured to press against the fed-out fiber portion,
the filament winding method comprising:
temporarily suspending operation of the winding device in a middle of winding the fed-out fiber portion around the workpiece; and
resuming the winding of the fed-out fiber portion around the workpiece by operating the winding device, after the temporarily suspending of the operation of the winding device,
wherein in the temporarily suspending of the operation of the winding device, a 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,
throughout the temporarily suspending of the operation of the winding device, the fed-out fiber portion extends from the fiber roll portion to the workpiece,
the fed-out fiber portion continues to be fed out from the fiber roll portion over the temporarily suspending to the resuming of the winding,
throughout the temporarily suspending of the operation of the winding device, a movement speed of the pressing member is made higher as a feed speed of the fed-out fiber portion from the fiber roll portion becomes higher, and
in the resuming of the winding, the pressing member is moved to an initial position while the pressing member is caused to press against the fed-out fiber portion.
