Sliver compacting device for spinning machine drafting system includes a soft pressure roller pressing against perforated compacting roller

摘要

The perforated compacting roller (35) or other compacting element has a pressure roller (16) with a surface Shore hardness of less than 60 deg pressing against it in the compacting region. The covering of the roller (16) can be a two-layered structure with a soft inner layer and an abrasion resistant outer layer. The surface of the compacting roller (35) is of controlled roughness, e.g. fluted.
