Definitions

  • the invention relates to a winding machine for winding a running Thread to a bobbin according to the preamble of claim 1.
  • the winding spindle by means of the rotating movement of a revolver during winding moved away from the stationary pressure roller.
  • the winding spindle is on a swing arm mounted relative to the turret by means of a force transducer is pivotable.
  • the winding spindle In the winding area, the winding spindle is closed with the forming coil pressed against the fixed pressure roller.
  • the rotary motion the turret to form the coil is controlled so that the relative position of the rocker on the turret remains unchanged.
  • the investment power between the pressure roller and the spool is from the power transmitter given.
  • the winding area is the size of the turret diameter dependent.
  • the spool In the winding machine known from DE 25 23 771, the spool is used receiving winding spindle by means of a linear guide during winding moved straight away from a pressure roller. The direction of action remains the contact force of the pressure roller relative to the coil surface constant. The pressing force is determined by means of a pneumatic cylinder.
  • the evasive movement between the pressure roller and the Coil staggered in stages with different directions of movement.
  • Each of the directions of movement is characterized by a typical guideway, on which the winding spindle is moved.
  • the particular advantage here lies in the fact that the changes in the weight component are very targeted the pressure roller due to the change in relative position between the coil and Pressure roller is used to influence the system force. In addition can make thick bobbins while maintaining small dimensions of the bobbin turret be wrapped.
  • the contact force between the spool and the pressure roller is at one movable pressure roller essentially by the weight of Pressure roller determined.
