Abstract (en)

[origin: WO9948786A1] The invention relates to a method for winding up a continuously fed thread on a spool (5) which is formed on a tube (6). To this end, the thread is guided back and forth within a traversing travel (H) by means of a thread guide (11), and is placed with a winding angle on the spool (5). The traversing thread guide (11) is slowed each time within a reverse distance section (B) by a finite deceleration of a guiding speed so that it can reverse at the ends of the traversing stroke, and is accelerated up to the guiding speed again by a finite acceleration. The acceleration and deceleration of the traversing thread guide are controlled in such a way that the length of the reversing distance section expands as the diameter of the spool increases.
