Patent ID: 7735536

Claim:
A filament winding apparatus for rotating in a predetermined direction a core material that is supported by a supporting portion, and for winding around the core material, an elongated material which has flexibility and which is impregnated with an unhardened synthetic resin material, the filament winding apparatus comprising: a plurality of feeding portions for feeding a plurality of elongated materials; and a plurality of guiding mechanisms which are positioned around the core material so as to correspond to the plurality of elongated materials that are drawn from the plurality of feeding portions, and through which the corresponding elongated materials are passed, wherein at least one of the supporting portion and the plurality of guiding mechanisms are movable in a rotation axial direction, from a winding operation range in which the elongated materials can be guided by the plurality of guiding mechanisms to winding positions at which the elongated materials are wound around the core material, to an attachable/detachable position at which a clearance in the rotation axial direction from the plurality of guiding mechanisms to the core material and the supporting portion is formed, wherein the plurality of guide mechanisms are disposed at different positions in the axial direction of the core material, and wherein each of the plurality of guiding mechanisms has an opening, each opening has an opening direction and is driven to individually turn around an axis perpendicular to the rotation axial direction to change the opening direction.
