Definitions
- the invention relates to a method for pushing off at least one thread spool according to the preamble of claim 1 and a device for pushing off at least one thread spool according to the preamble of claim 6.
- winding machines are preferably used for winding up with two cantilevered winding spindles which are arranged on a movable carrier and are alternately guided into a winding area and into a changing area. This means that the melt-spun threads can be wound into thread spools continuously without interrupting the process.
- a winding tube is slid on and clamped on the circumference of the winding spindle per winding point, on the circumference of which the thread is wound into a thread spool.
- the winding spindle which is held in an alternating area, cooperates with a push-off device in order to be able to push off the thread spool that has been completely wound around the circumference.
