Abstract:
1. Method for coiling thin metal strip, especially hot-rolled or cold-rolled thin steel strip ( 1 ), on a coiler mandrel ( 3 a ), which is adjusted in diameter, to form a coil, the method comprising initially coiling inner windings ( 12 , 18 ) of the coil on the adjusted coiler mandrel diameter, and, after winding of the coil ( 11 ) is complete, pulling the coiler mandrel ( 3 a ) out of the coil, or taking the coil ( 11 ) off the coiler mandrel, wherein the inner windings ( 11 , 12 ) of the coil ( 11 ) are mechanically directly supported along an inner circumference during or immediately after the removal of the coil ( 11 ) from the coiler mandrel ( 3 a ) in an eye ( 15 ) of the coil, the support of the inner windings of the coil being by linear radial expansion of support elements perpendicular to a central axis of the coil, the support elements being arranged completely within the eye.
