Abstract

A spinning machine and method of operation include a plurality of adjacently arranged workstations, each workstation having one of a spinning device or a suction nozzle to which a process vacuum is applied during spinning operation. A vacuum duct extends along the workstations for supplying the spinning devices or the suction nozzles with the process vacuum. A maintenance unit is displaceable along the workstations, the maintenance unit including a pneumatic working element and a vacuum line to supply the pneumatic working element with vacuum. A closeable connection opening is at each of the spinning devices or the suction nozzles, the connection opening connected to the process vacuum. The maintenance unit includes a suction head that is advanceable toward the connection opening and is connected to the vacuum line.
