Abstract
Disclosed is a filament winding apparatus comprising a winding mechanism having a pair of arms for winding traversed filamentary yarns impregnated with a resin onto a plurality of mandrels, respectively, and a mandrel retaining mechanism having mandrel receiving portions by a number of at least two times of the number of the mandrels to be set on the arms of the winding mechanism. The arms are swung between a winding position and a mandrel exchange position of the mandrel retaining mechanism. The retaining mechanism is a little moved when the mandrels are exchanged. A plurality of mandrels can be easily and efficiently exchanged at the same time without a particular device. The number of the mandrels for simultaneous filament winding can be increased and a high productivity can be obtained. Further, this apparatus can be realized at a relatively low cost.
