Abstract
A filament winding apparatus includes a controller that controls the action of the filament winding apparatus. The controller includes a tension controller that controls a tension adjuster in such a way that an adjusted tension waveform that relates the rotation phase of a liner to the tension of a fiber adjusted by the tension adjuster has a phase opposite to the phase of a temporary tension waveform.
