The weld seam is stopped in front of the first stand, the second stand continuous to roll the strip (7) in front of the seam, which is supplied from a store (6) between the stands. The first stand is opened, the seam is passed through, the stand is closed, the seam passes through The store, and is stopped in front of the second stand, while the first stand rolls the strip behind the seam and the rolled strip is taken-up by the store. The second stand is opened, the seam is passed through, the second stand is closed, and the seam is cut out of the strip.
