Abstract: In this process for winding a filament around a winding support (6) having a general cylindrical shape held by a holding device (4) fixed to a base (18), the following steps occur in synchronization: (i) feeding a filament (24), by means of at least one feeding device (22), towards the winding support (6), (ii) rotating the winding support (6) with respect to the base (18) around a pitch axis (10) of the winding support (6), (iiiA) rotating unlimitedly the at least one feeding device (22) around a yaw axis (12) of the winding support (6) with respect to the base (18), and/or (iiiB) rotating unlimitedly the winding support (6) around the yaw axis (12) of the winding support (6) with respect to the base (18), (iv) rotating unlimitedly the winding support (6) with respect to the base (18) around a roll axis (8) of the winding support.

Abstract: In this process for winding a filament (22) around a winding support (6) having a general cylindrical shape with dome-shaped longitudinal ends and having a roll axis (8), the winding support (6) being held by a holding device (4) fixed to a base (16), the following steps occur in synchronization: (i) feeding a filament (22), by means of at least one primary feeding device (18) and at least one secondary feeding device (20), towards the winding support (6), (ii) translating the primary feeding device (18) and the secondary feeding device (20) with respect to the base (16) in parallel to the roll axis (8) of the winding support (6), (iii) rotating the winding support (6) around its roll axis (8) with respect to the base (16), wherein the movement of the primary feeding device (18) and the secondary feeding device (20) are symmetric one of another.
