1. A spinning machine, comprising:
a plurality of adjacently arranged workstations, each of the workstations comprising a spinning device impingeable with vacuum to manufacture a thread, and each of the workstations having a workstation-specific suction nozzle impingeable with vacuum that seeks a thread end on a package;
at least one first suction system comprising at least one first vacuum source and at least one first vacuum duct extending along the workstations;
the spinning devices of the workstations connected to the first suction system;
at least one second suction system comprising at least one second vacuum source and at least one second vacuum duct extending along the workstations;
the second suction system isolated from the first suction system such that the first suction system comprises a first vacuum level (pU1) and the second suction system comprises an independent second vacuum level (pU2);
wherein the suction nozzles of at least a first partial number of the workstations are connected to the second suction system; and
wherein the the second vacuum level (pU2) is greater than the first vacuum level (pU1).
