Abstract
In a spinning and winding machine, a continuously fed yarn is wound into a cross-wound bobbin. When a predetermined diameter of the cross-wound bobbin has been reached, the cross-wound bobbin is replaced by an empty bobbin holder. The yarn is moved to a lateral area next to the winding zone. The yarn is guided during all winding and bobbin replacement processes by a microprocessor-controlled step motor, by means of a cross-winding guide.
