SHEET MATERIAL COIL, METHOD OF AND MACHINE FOR COIL MAKING Russian patent published in 1997 - IPC

Abstract RU 2091288 C1

FIELD: mechanical engineering; making of coils of material wound without central core. SUBSTANCE: machine has first winding roll around which material is passed, and second winding roll which limits, together with first winding roll the clearance to pass material. Member is provided which can be shifted relative to first winding roll and cyclically displaced towards surface of first winding roll with material between member and roll to clamp and, consequently brake material between member and roll thus tearing off the material and providing the beginning of winding of leading edge formed at tearing off of material around itself. EFFECT: enlarged operating capabilities. 48 cl, 21 dwg
