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 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.

Abstract: Each of the thread guide wings comprises a pair of leg members. Teeth located at the leg members of each pair mesh with an associated gear secured to an associated concentrically arranged adjustment shaft. By accomplishing relative motion between the adjustment shafts, which carry the thread guide wings, and the associated gear it is possible to adjust the diameter or lengthwise extent of the thread guide wings by displacing the leg members. A corresponding reduction or enlargement of the diameter or lengthwise extent of the thread guide wings causes a displacement of the thread transfer points and thus the stroke along which the thread is shifted. Altering the thread stroke can be accomplished by a stepping motor or as a function of the diameter of the bobbin upon which the thread is wound.

This is exactly half as large as the spacing (y) between two adjacent carriers (28a-28d).
