A spinning rotor of an open-end spinning device is slowed down for piecing to a low rotational piecing speed and is then accelerated to the operating speed. For this purpose, the spinning rotor or an element in driving connection with it is presented a drive transmission device from a service unit by means of which the spinning rotor can be switched from normal production speed to a reduced piecing speed and back. In this process, the drive transmission device can be driven either by a driving apparatus installed on the service unit or by a drive belt extending within spinning machine. The driving apparatus mounted on the service unit is connected to a control device for the control of the evolution of the rotational speed of the spinning rotor. The spinning rotor is driven according to a rotational speed course controlled by means of a program applied by the control device during the time when its rotational speed deviates from its operating speed.
