- the energy and signal transmission is preferably carried out via a rotary transformer from the frame plate to the movable support.
- a changeover device takes over the management and transfer of the band-shaped winding material.
- the changing device is preferably arranged on the carrier and has a movable thread guide at least for each winding point.
