ABSTRACT:
A method for winding a yarn in a random wind at a rated traversing frequency in a predetermined course, and so as to produce a ribbon free randomly wound package. For avoiding ribbon formations, a critical range characteristic of a ribbon is traversed at a changed traversing frequency. In particular, the traversing frequency is slowed down constantly or in steps upon entry into the critical range, and it is increased suddenly in the further course within the critical range to a value above the rated traversing frequency. After increasing the traversing frequency, same is slowed down constantly or in steps, so that upon exit from the critical range the traversing frequency assumes the value of the rated traversing frequency.
