Abstract
A spinning machine having a drafting frame, a condensing unit at the downstream side of the drafting frame and a spinning station for winding up the yarn and imparting twist to the roving in forming the yarn. The condensing unit comprises a disk-shaped suction rotor oriented in a plane tangent to the output rollers of the drafting frame. A limited compaction zone is formed by a shield within a suction rotor and designed to apply suction only to a limited portion of the perforated periphery thereof. The pressing roller bears against the suction rotor at the downstream side of the compaction zone.
