ABSTRACT:
A method and apparatus for reestablishing the spinning operation of an open-end spinning machine following completion of spinning of a full package. The apparatus uses a traveling service unit having a device for forming a yarn reserve on a projecting end of a full package, a device for removing the full package with the yarn reserve thereon, a device for placing an empty tube in position for winding, a device for preparing an end of auxiliary yarn for restart feeding to the spinning element, a device for feeding the end of auxiliary yarn to the spinning element to restart spinning and withdrawing restarted yarn from the spinning element, and a device for engaging the restarted yarn on the empty tube to reestablish the spinning operation. The forming of the yarn reserve is performed while the end of auxiliary yarn is being prepared for restarting of spinning. The package is removed while the auxiliary yarn end is being fed to the spin box for restarting of spinning. The new tube is being placed while restarted yarn is being withdrawn from the spin box and being fed onto the tube. The normal spinning operation is then resumed.
