To provide a technique capable of optimizing the distance between the adjacent sliver guides.
A plurality of helical heads 43 (44) which is provided fiber bundle guide 91 moves in a substantially vertical direction (92) radially to the rotational axis Ra of the liner 1, wherein while rotating the liner 1 helical head 43 (44 ) in the filament winding apparatus 100 which will wind the fiber bundle F on the outer peripheral surface 1S of the liner 1 in order to pass the, provided on one of the helical head 43 (44) perpendicular to the axis Ra of the liner 1 fiber bundle guide 91 (92) of the guide hole 91a and the imaginary plane Pf intersecting the (92a), the perpendicular to the rotary axis Ra of the liner 1 other of said fiber bundles provided in the helical head 44 (43) Guide 92 (91) and the virtual plane Pw intersecting the guide port 92a (91a) of the, provided gap adjusting means 50 for adjusting the spacing.
