Abstract
A top roller unit is arranged on a top weighting arm for a drafting apparatus of a spinning machine, which top roller unit has a holding device and two double top rollers and is arranged at two adjacent spinning stations. A first top roller of a spinning station borders a drafting zone which serves to draft a fiber strand, and a second top roller of a spinning station borders a condensing zone which serves to condense the fiber strand and which is arranged downstream of the drafting zone. The second top roller of each spinning station is driven via a drive by the first top roller, which drive takes the form of an intermediate gear which is common to all the top rollers of the top roller unit. The top roller unit is supported by a housing which encapsulates the intermediate gear.
