Open-end spinning machine apparatus is provided for accommodating sequential preparation of a plurality of spinning units of a spinning machine so that they may thereafter be simultaneously started up by common drive means with simultaneous thread piecing operations taking place at each of the spinning units. The piecing preparation apparatus includes one or more mobile units having cleaning apparatus for cleaning the spinning units and apparatus for preparing and transferring a thread end from a bobbin at each of the spinning units to the respective spinning rotors. Certain embodiments of the invention utilize a mobile piecing device which is operable to preform piecing operations at individual spinning units during normal operation of the spinning machine, to also carry the equipment for preparing the plurality of individual spinning units when the machine is completely shut down.
