A machine for filament winding, in particular on a liner for the manufacture of tanks, comprising a displacement system able to drive a body in rotation around its longitudinal axis (A) and to effect a relative displacement of the body with respect to winding means. The winding means comprise a rotating support, mounted so as to rotate around a rotation axis (B), on which are mounted at least two winding systems, each winding system comprising a winding head associated with storage means, so that, by rotation of said rotating support around its rotation axis (B), each winding system can be displaced into an active position for winding fiber via its winding head, and an inactive position in which an operator can perform maintenance operations.
