摘要：
A drafting unit for a spinning machine has several stub shaft supported bottom rollers which are each assigned to a spinning point and which are in driving connection with drive shafts extending through in longitudinal direction of the machine. To facilitate servicing operations, the bottom rollers are held by means of support components which are detachably mounted at a machine frame which accommodates the drive shafts.
