METHOD FOR AUTOMATIC STRAIGHTENING OF FIBROUS MATERIAL IN SINGLE-ZONE DRAWING APPARATUS Russian patent published in 2003 - IPC

FIELD: textile industry. SUBSTANCE: method involves changing draft between cylinder-roll drawing pairs by automatic converting of material thickness into draft, which is parametrically changed through converting fibrous material thickness until it is drawn into gap between roll and cylinder of first drawing pair in the course of advancement of material; simultaneously kinematically changing draft by converting thickness of fibrous material into rotational speed of second drawing pair cylinder after fibrous material is drawn. EFFECT: simplified process, increased straightening precision, intensified straightening and complete straightening process regardless of speeds. 1 dwg
