Abstract

The invention relates to a method for preventing shape changes in metal coils, in particular for preventing a collapsing of newly wound hot coils. In the method, a metal coil, in particular a newly wound hot coil, is rotated about its longitudinal axis intermittently in a first rotational direction and then rotated back in a second opposing rotational direction, or further rotated in the first rotational direction.
