Beschreibung
Zusammenfassung:	A drafting device for a textile machine, in particular an air-jet spinning machine, wherein the drafting device can have a plurality of roller pairs which can be driven differently from one another. The roller pairs can be designed and arranged to guide a sliver between a top roller and a bottom roller of the roller pairs during their rotational operation in order to stretch the sliver. The drafting device can be designed and configured to carry out a piecing process after the sliver has been severed in the drafting device. In order to optimize a spinning process, it is provided that the drafting device is designed and configured to engage at least two roller pairs via their drive in a defined manner during the piecing process.
