Definitions

  • the invention relates to a method for winding a continuously incoming thread according to the preamble of claim 1 and a Winding device for winding a continuously tapered Thread according to the preamble of claim 7.

  • a so-called thread reserve winding was wound on the core, starts winding the spool.
  • To catch and start the Thread passed through a movable auxiliary thread guide before the thread is released for the actual winding trip.
  • Such winding devices are used, for example, in texturing machines used to wind a textured thread into a spool. in this connection becomes the continuously tapering thread before catching and tackling on the empty tube taken over by a suction device.
  • the suctioned thread is fed to a waste container. Therefore, the aim is the time during which the thread is guided in the suction device will be kept as short as possible - that is, with every spool change.
  • EP 0 311 827 shows a method and an apparatus in which which thread during a bobbin change by means of a Stepper motor driven traversing thread guide is guided. in this connection there is no need to hand over the thread after catching and winding Traversing device.
  • this method and device also have this the disadvantage that the bobbin change phase during the thread drop arises, takes a relatively long time.

This is particularly advantageous in cases where the thread is in the Catcher initially on a larger diameter than the sleeve diameter is caught. Therefore, in order to adhere to an essentially constant winding speed of the thread with the speed of the Sleeve rotating safety gear with a lower speed than that Spool speed be driven while catching.
  • a particularly advantageous method variant according to claim 2 has the Advantage that the thread is reached immediately without significant delay a catching position of the thread guide is caught by the catching device. Since the thread continues to be guided in the suction device until it is caught this variant leads to a further reduction in the amount of waste from the Thread.

This will be the end of the thread clearly visible on the full spool.
  • the method variant according to claim 5 leads to a particularly gentle thread transfer to a suction device, since the thread is none receives significant deflections that lead to significant changes in thread tension to lead.
  • the device according to the invention has a sensor that measures the speed the sleeve detects and the signal of the speed in the control device gives up, which controls the drive of the thread guide. This ensures that the movement of the thread guide only after reaching a predetermined Spindle speed is executed by the drive.
  • Claim 8 is particularly suitable to ensure safety when catching to increase the thread.
  • the time during the thread becomes extreme is deflected in order to offer the thread of the catching device for catching, significantly shortened.
