Abstract
A method for coiling thin metal strip (1), especially hot-rolled or cold-rolled thin steel strip, on a coiler mandrel (3a) 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 (3a) 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.
