Only for the u. U. shorter lasting process of changing the bobbins on the spindle is a separate operation required, bringing the operating times u. U. are reduced. Furthermore, the reliability of the winding process can be ensured for this embodiment, even in the event of failure of the bobbin tube tensioning device, without it being possible for the winder and dangerous operating situations to be impaired.
