Abstract

For a rolled metal strip, in particular a steel strip; a drive roller unit deflects the metal strip from a first transportation direction to a second transportation direction, and the strip is then fed to a coiler. The metal strip is coiled in the coiler to form a coil having a coil diameter. Plastic deformation of an end portion of the metal strip is caused such that the end portion in its uninfluenced state is curved at a curvature radius. The plastic deformation of the end portion () is at least partially caused by an asymmetric impingement with a cooling medium () on the sides of the end portion (). The impingement of the end portion () with the cooling medium () is performed across a length of the end portion () that is longer than half the outermost coiling of the coil () but smaller than the outermost coiling of the coil ().
