This will prevents the supply reel from running. To always have a certain basic thread tension to ensure it is expedient to use the switched off winding drive the braked supply spool and bring it to a standstill over the thread.
  • the regulation of the rotational resistance of the supply spool is either via thread sensor signals made, or by applying current to the winding drive representing run or stop signals, i.e. taking into account the current applied or the currentless state of the winding drive.
