In a cross-wound bobbin ( 1 ), the helical lines along which the yarn ( 4 ) is wound have a different inclination in adjacent layers. The winding ratios are selected such that the quantity drawn off is greater if the unwinding point is moving from the unwinding end to the bottom end, compared to the quantity drawn off if the unwinding point is moving from the bottom end to the unwinding end.
