Abstract
In the case of a drafting arrangement for a spinning machine, at least one drafting zone has a sliver guide with a guiding surface for the travelling sliver. The sliver guide is arranged in a wedge-shaped gap, which is formed by a roller pair downstream of the drafting zone. According to the present invention, the sliver guide comprises a sliver brake with a pressing element which slides on the sliver. The pressing element is resilient with a pressure in the direction towards the guiding surface, and is disposable against the travelling sliver. The evenness of the drafting is thereby improved.
