In open-end spinning and in coordination with predetermined operating phases, a yarn suction pipe by means of which a yarn extending from a bobbin is to be received temporarily is brought successively into different operating planes. The yarn suction pipe is imparted a defined operational movement as a function of the operating planes occupied and in coordination with the current operating phase. The operating positions of the yarn suction pipe that can be moved into at least two operating planes are defined in such a manner that when the yarn suction pipe is in its operating position in a first operating plane, a yarn extending from the bobbin pressing on a winding roller to the yarn suction pipe crosses the traversing range of the yarn traversing guide. However, the yarn is outside the traversing range of this yarn traversing guide when the yarn suction pipe assumes its operating position in an additional operating plane. The yarn suction pipe is mounted on a swivel pin that is in turn mounted on an additional swivel pin.
