Abstract
A filament winding apparatus includes a hoop winding device and a helical winding device. The hoop winding device includes a disc-shaped wrapping table, a drive mechanism that rotatably drives the wrapping table, four bobbins supported along a peripheral edge of the wrapping table, and a guide member that moves and guides a fiber bundle fed from the bobbin to a mandrel arranged in an insertion hole of the wrapping table. The bobbin is axially supported in a freely rotatable manner with a chuck of a holder fixed to the wrapping table. A ratchet mechanism, which prevents over-rotation in a fiber bundle feeding direction of the bobbin, is arranged between the holder and the chuck.
