Abstract
A process is provided for preventing ribbon windings when cross-wound bobbins are wound in random winding on a textile machine. The thread from a thread guide is traversed over a double stroke. The traversing frequency of the thread guide is continuously varied during the bobbin travel within a predetermined deviation range around a nominal frequency. A random stringing together of individual interference patterns is generated by a random generator by selecting a target value for the traversing frequency from the deviation range for every interference pattern. The traversing frequency is adjusted by a control device on the selected target value.
