Abstract

A rotor spinning machine of the type comprising a plurality of working stations and a bobbin supplying device extending along the machine, wherein at least two service units supplying the working stations with bobbins are supplied by the supply device and wherein the rotor spinning machine comprises a control device for controlling the service units. The control device is configured in such a way that it suppresses a subsequent bobbin request from the second service unit in the event of an existing bobbin request from the first service unit positioned downstream in relation to the transporting direction of the supply device, until the initially existing bobbin request has been fulfilled.
