Abstract (en)
[origin: EP1321547A1] To wind cylindrical cross wound bobbins (3), at a rotor spinning machine, the wound body (12) is formed by a reciprocating yarn guide to give a yarn intersection angle ( alpha M) at the center zone (22) which is ≤ 26 degrees . The yarn angle towards the end zones (20,21) has a larger yarn intersection angle ( alpha R). The center zone of the bobbin is ≥ 50% of the total bobbin width (BWG).
