  • the invention has for its object to provide a method of the type mentioned and a thread processing system with which in particular tensile and extremely powerful thread material can be processed easily
  • tangential removal of the thread from the supply spool avoids the problems resulting from an overhead take-off from the supply spool.
  • the winding drive of the thread delivery device generates the thread tension for turning the rotatably arranged supply spool
  • the thread runs cleanly and without twisting into the thread delivery device as required by the winding drive
  • the rotatably arranged supply spool enables the winding drive to take off exactly the thread quantity required per unit of time
  • the supply spool is rotatably mounted and positioned in such a way that it permits tangential removal of the thread by the thread delivery device.
  • the winding drive of the thread delivery device functions as a rotary drive for the supply spool, in that at least the thread tension caused by the winding drive utilizes the torque required for the corresponding rotation of the supply spool the tensile strength of the thread is generated surprisingly easily the problems caused by the thread material
  • the rotational resistance of the supply spool is expediently actively regulated. This is an essential procedural feature and takes into account the fact that the winding drive must be accelerated relatively quickly to a high speed and the supply spool has to be carried along or brought to a standstill relatively quickly, the Supply spool could then run on.
  • a largely constant thread tension can be used as a parameter for the control of the rotational resistance. The control is preferably carried out approximately synchronously with changes in speed of the winding drive.
  • the winding drive provides the necessary rotation of the supply spool, it is controlled by regulating the drag resistance Supports the supply spool, if necessary by a corresponding reduction in the rotational resistance that can be felt by it by an additional movement of the supply spool, or when stopping by a subsequent increase in the turning range of the supply spool to avoid overrun

  • the rotational resistance of the supply spool is only changed between free running in its rotational position and complete standstill.
  • the complete standstill of the supply spool is brought about as soon as a fade sensor signal causing the winding drive to come to a standstill or the current application to the winding drive is switched off
