Abstract
An open-end spinning apparatus includes a rotor housing. A spinning rotor revolves in the rotor housing. A spinning insert is disposed coaxially to the rotor housing and is rotatably supported relative to the spinning rotor. The spinning insert has a yarn guide channel enabling entrainment of the spinning insert by a yarn during normal spinning operation. A coupling device fixes the spinning insert to the spinning rotor during a run-up of the rotor.
