Abstract
A device for compacting a fiber composite on a spinning machine includes consecutive drafting arrangement roller pairs. A compaction unit is pivotably mounted on the machine frame downstream of the delivery roller pairs with a pivot axis parallel to the rotational axes of the delivery roller pair, and includes a support with a suction drum rotatably supported on the support. At the end of a suction zone of the drum, a nip roller is fastened to the support to form a nip line. The support is spring-loaded to form a drive connection between the lower roller of the delivery roller pair and the suction drum, wherein the suction drum is moved against the lower roller. Guide means fix the compaction unit in position as mounted on the machine frame, and the spring element is mounted on the free end of the pressure lever.
