ABSTRACT:
An apparatus and method for winding a yarn in a wild winding onto a package, includes a reversing screwthread shaft (1) having an endless screwthread groove (2) and a yarn guide which produces in particular a creep stroke motion. The reversing screwthread shaft (1) has a turns number which establishes a double stroke having a forward stroke (3) and a reverse stroke (4) and which includes a mixed number and whose integral component is .gtoreq.2 and the balance of which represents a true fraction, and has on each side a plurality of reversals (5) which in particular are arranged in axially displaced relationship with each other. A half turns number which establishes a forward stroke (3) and a half turns number which establishes the associated reverse stroke (4) are the same.
