Abstract
A winding process for winding yarn into a cross-wound bobbin in the textile machine includes depositing the yarn on a bobbin in a transversing stroke by a transversing movement of a yarn guide. The process includes intermittently decreasing the traversing stroke from a maximum value to a minimum value and then increasing the value of the traversing stroke from the minimum value back to a relatively constant maximum value and holding the stroke at the maximum value for a predetermined period of time. The traversing frequency of the yarn guide is decreased to a relatively constant minimum value substantially simultaneously with the increasing of the traversing stroke from the minimum value back to the relatively constant maximum value. The traversing frequency is maintained at the constant minimum value for a predetermined period of time. The traversing frequency of the yarn guide is then increased from the constant minimum value after the predetermined period of time. The duration of the decreasing of the traversing frequency of the yarn guide is shorter than the duration of the maximum value of the traversing stroke.
