DEVICE FOR WINDING LONG-CUT MATERIALS ON MANDREL Russian patent published in 1999 - IPC

FIELD: light industry; coiling of long-cut materials at processing on checking and measuring and rewinding machines. SUBSTANCE: proposed winder has extensible support and winding drums installed on cantilevers for synchronous rotation together with drums relative to intermediate shaft. Drum extending mechanism provided constant angle of roll contact with support and winding drums and constant peripheral velocity of roll at changing of its radius. EFFECT: reduced deformation in inter-drum zone, improved quality of winding. 4 dwg
