Abstract
A filament winding apparatus includes a tension detecting section, a cutting section and a gripping section. The tension detecting section is arranged on a path of a fiber bundle from a bobbin to a liner, and is configured to detect tension of the fiber bundle between the bobbin and the liner. The cutting section is configured to cut the fiber bundle connected to the bobbin. The gripping section is arranged upstream with respect to the cutting section in a travelling direction of the fiber bundle, and is configured to grip the fiber bundle cut by the cutting section. At this time, in a case where the tension of the fiber bundle detected by the tension detecting section is excessive, the cutting section cuts the fiber bundle and the gripping section grips a yarn end of the fiber bundle connected to the bobbin.
