A method for coiling thin metal strip on a coiler mandrel, which is adjusted in diameter, in which, at the beginning, the inner windings of the coil are coiled on the adjusted coiler mandrel diameter, and, after the final winding of the coil, the coiler mandrel is pulled out, or the coil is taken off. One or more profile grooves are pressed into one inner winding or into several adjacent inner windings on the circumference during rotation of the coil.
