Abstract

In the case of a drafting unit for a spinning machine comprising several top rollers and bottom rollers, continuous cleaning belts are provided which are arranged and held in such a manner that, because of the inherent weight of at least one of the deflecting rollers, they are tensioned, on the one hand, and, on the other hand, are brought to rest against the top rollers or bottom rollers.
