Abstract

A method and a device for rolling a metal strip (1) in a rolling train, the rolling train having at least two rolling stands, the metal strip (1) having at least two partial areas (3, 4) of different thicknesses, which are connected to one another via a wedge-shaped or approximately wedge-shaped transition piece (2), and the rolling velocity of a rolling stand, during the rolling of the wedge-shaped or approximately wedge-shaped transition piece (2), being set as a function of the forward slip of the rolling stand and of the temperature of the metal strip.
