摘要： The invention relates to a cross-wind bobbin (1) wherein the helical lines in which the yarn (4) is wound have a different pitch in adjacent positions. The winding ratios are selected in such a way that the amount which is drawn off is greater when the draw-off point is displaced from the draw-off side to the base than the amount which is drawn off when the draw-off point is moved from the base to the draw-off side.

摘要： The invention relates to an overhead unwinding crosswound bobbin (1) and to an associated production method, in which the thickness of the finished crosswound bobbin (1) is increased and the sequence of operations in further processing is optimised. To achieve this, in one embodiment the yarn is wound in parallel convolutions (17) that are a distance apart. In another embodiment, the yarn (4) is wound onto a bobbin with a small diameter (D) at a more acute inclination angle than for a bobbin with a larger diameter (D). In addition, a traversing stroke (H) that is reduced in relation to the bobbin width (B) is displaced along the bobbin width (B).
