The invention relates to a method for rolling a product in a rolling train comprising at least two roll stands having a roll gap, the product to be rolled comprising a transition region. If a critical transition region crosses the rolling train, the roll gaps of the roll stands are successively opened and closed according to the position of the transition region moving at speed through the rolling train, in the direction of the direction of travel of the conveyor. The opening of the roll gaps occurs parallel to the position of the critical transition region when the product is displaced. A transition region is critical when the structure requires the roll gaps to be opened. The inventive opening of the roll gaps, when the device is moving, enables the controlled transition of a product to be rolled with extreme variations in dimensions and/or hardness, for a shorter length.
