Abstract: A process for winding a filament around a winding support having a general cylindrical shape with dome-shaped longitudinal ends and having a roll axis, by which the winding support is held by a holding device fixed to a base. The following steps occur in synchronization: (i) feeding a filament, by at least one primary feeding device and at least one secondary feeding device, towards the winding support; (ii) translating the primary feeding device and the secondary feeding device with respect to the base in parallel to the roll axis of the winding support; and (iii) rotating the winding support around its roll axis with respect to the base, where the movement of the primary feeding device and the secondary feeding device are symmetric one of another.

Abstract: A process for winding a filament around a winding support. The winding support has a cylindrical shape with dome-shaped longitudinal ends and a roll axis, and is held by a holding device fixed to a base. The process includes the following, occurring in synchronization, feeding a filament, by means of at least one feeding device, towards the winding support, rotating the winding support with respect to the base around a pitch axis of the winding support, rotating unlimitedly the at least one feeding device around a yaw axis of the winding support with respect to the base, and/or rotating unlimitedly the winding support around the yaw axis of the winding support with respect to the base, and rotating unlimitedly the winding support with respect to the base around the roll axis of the winding support.
