Claim:
1. A method for adapting a travel end position of a changing movement a thread to a flange spool, the thread being moved back and forth during a spooling operation along a rotation axis of the flange spool relative to the flange spool by means of a changing thread guide, the method comprising the following steps of: time-resolved detecting of a thread tension of the thread which is intended to be spooled on the flange spool; establishing a changing rate of the thread tension when the thread moves away from a flange-side travel end position of the changing movement using the detected thread tension, the changing rate of the thread tension being averaged over a defined time measurement range; determining a deviation of the changing rate of the thread tension from a desired changing rate which is predetermined for the thread tension; and adapting the flange-side travel end position by means of axial adjustment of the travel end position and the flange spool relative to each other using the changing thread guide after determining a changing rate of the thread tension which is less than or greater than a predetermined desired changing rate, the flange-side travel end position being moved away from the flange of the flange spool in an axial direction by means of the changing thread guide when the changing rate of the thread tension is negative, that is to say, when the thread tension decreases when the thread is moved away from the flange-side travel end position, and the flange-side travel end position being moved by means of the changing thread guide in an axial direction towards a flange of the flange spool when the changing rate of the thread tension is positive, that is to say, when the thread tension increases when the thread is moved away from the flange-side travel end position.
