Abstract
Provided are a filament winding method and a filament winding apparatus, in which, when a new bobbin is mounted on a bobbin rotation driving device, the control device is programmed to rotate the bobbin and oscillate a dancer while maintaining a state where a distal end of filament unwound through the dancer is fixed further beyond the dancer and the filament is stretched. The control device is programmed to obtain a bobbin diameter of the bobbin mounted on the bobbin rotation driving device based on a length of the dancer, an oscillation angle of the dancer, and a rotation angle of the bobbin.
