ABSTRACT:
In order to form a yarn reserve winding on the edge of a rotating empty winder tube after a doffing action on a package-producing spinning aggregate, the rotational speed of a drive roller which drives the winder tube is kept constant. The delivery speed of a delivery device, which draws the yarn from the spinning aggregate and delivers it to the winder tube, can be regulated. The yarn tension between the delivery device and the winder tube is thus kept constant during the forming of the yarn reserve winding as well as during and after the transfer of the yarn to a traversing device.
