helical winding is reliably carried out in a plurality of patterns at different angles in a short period of time . a filament winding apparatus for winding fiber bundles onto the surface of a mandrel includes a helical winding head for use in helical winding of the fiber bundles onto the mandrel . the helical winding head includes at least two guide arrays , each including a plurality of guide portions disposed along a circumferential direction of the mandrel , and a repositioning mechanism capable of repositioning the guide portions by rotating each guide array relative to another .
