A spinning machine includes a plurality of work stations arranged side by side between two front-side ends along at least one longitudinal side of the spinning machine. Each work station has a draw-off device, and an individual drive for the draw-off device. Each work station further includes additional driven work elements for production and winding of a yarn, the additional work elements including at least a feed device, a spinning chamber, and a winding device. A suction device generates negative pressure at the work stations and includes at least one negative pressure source and at least two negative pressure channels. Each of the negative pressure channels extends in a longitudinal direction of the spinning machine only over one part of the work stations.

The invention relates to a spinning means for a work station of a textile machine having a plurality of work stations, comprising a first spinning means identification for identifying and/or authenticating the spinning means at a work station. Furthermore, the invention relates to a textile machine having a plurality of work stations and a method for operating the same, wherein the work stations have replaceable spinning means, each having a first spinning means identification. In order to provide a spinning means that has a particularly forgery-proof spinning means identification, it is provided that the first spinning means identification is formed by at least one specific, sensor-detectable material property of a spinning means material and/or a coating applied to the spinning means material. In order to provide a method for operating a textile machine which prevents operation with unsuitable spinning means, it is provided that the first spinning means identification formed by a material property of the spinning means is monitored by a sensor device and, depending on the detected material property, operation of the respective work station is blocked or limited.
