Method and device for coiling thin metal strip, especially hot-rolled or cold-rolled thin steel strip
A method for coiling thin metal strip ( 1 ), especially hot-rolled or cold-rolled thin steel strip, on a coiler mandrel ( 3 a ) which is adjusted in diameter. At the beginning, the inner windings ( 12 ) of the coil are coiled on the adjusted coiler mandrel diameter, and, after the final winding of the coil ( 11 ), the coiler mandrel ( 3 a ) is pulled out, or the coil ( 11 ) is taken off. One or more profile grooves ( 17 ) are pressed into one inner winding or into several adjacent inner windings ( 12 ) on the circumference during rotation of the coil.

9 . 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, in which, at the beginning, the inner windings ( 12 , 18 ) of the coil are coiled on the adjusted coiler mandrel diameter, and, after the final winding of the coil ( 11 ), the coiler mandrel ( 3 a ) is pulled out, or the coil ( 11 ) is taken off, wherein the inner windings ( 11 , 12 ) of the coil ( 11 ) are mechanically supported along the circumference during or immediately after the removal of the coil ( 11 ) from the coiler mandrel ( 3 a ) in the eye ( 15 ) of the coil.
10 . Method in accordance with claim 9 , wherein the inner windings ( 11 , 12 ) are supported by radial expansion of support elements ( 19 ) away from a central axis.
11 . Method in accordance with claim 9 , wherein the supporting of the inner windings ( 11 , 12 ) overlaps the removal of the coil ( 11 ) from the coiler mandrel ( 3 a ).
12 . Method in accordance with claim 9 , wherein the support elements ( 19 ) are kept in their supporting position during the coil conveyance and cooling phase, and up to the uncoiling of the coil ( 11 ).
