    Abstract: In winding a yarn Y onto a bobbin (7), a more uniform package can be obtained by the alternate steps of (a) repeatedly traversing the yarn Y over a full traverse stroke Wo and (b) repeatedly traversing the yarn Y over a narrower traverse stroke W. During step (b) the yarn Y is released from the traverse guide means (10; 20-25) at the end of the stroke, whereupon it tends to traverse naturally towards a mid-position until picked up by the traverse guide means (10; 20-25) on its return stroke. The release is effected by yarn release guides (16a, 16b; 27a, 27b) which can be moved to a position where the yarn Y is deflected to a path where it is out of contact with the traverse guide means (16a, 16b; 27a, 27b) at a position corresponding to the ends of the narrower traverse stroke W.
