Method for the production of a strip comprising a staggered profile that runs in the longitudinal direction thereof

Method for producing a strip the width of which is defined by the two longitudinal edges thereof, which is made of at least one first metallic or predominantly metallic material, and in which the region, across which the first material extends, is provided with a boundary area that extends in staggered manner between the two longitudinal edges over the cross-section of the strip, comprising the steps of

• (a) combining strips of different widths, which contain the first material and which as such do not comprise a staggered boundary area between their two longitudinal edges, only in a roll nip or before a roll nip to form a first arrangement of strips having a staggered boundary area;
• (b) complementing the first arrangement of strips by placing one or more additional strips in the first arrangement in a roll nip or before a roll nip to form a second arrangement of strips having a rectangular cross-section;
• and
• (c) bonding at least the strips of the first arrangement of strips to each other by rolling, wherein the material of one, more or all additional strips that complement the first arrangement of strips to form the second arrangement of strips is selected to ensure that it will form no or only a considerably weaker bond with the strips of the first arrangement by the rolling operation than the bond between strips of the first arrangement, and that theses additional strips, whose material is selected in the described way is removed from the second arrangement of the strips after the rolling process.
