Abstract

The invention relates to a method for producing tailored sheet-metal strips, in which at least one sheet-metal strip having a substantially planar surface is integrally connected along its longitudinal edge to at least one further web-shaped semifinished product made of metal, wherein the at least one further web-shaped semifinished product differs from the at least one sheet-metal strip in terms of at least one of its properties, and wherein the at least one sheet-metal strip and the at least one further web-shaped semifinished product are fed continuously to at least one joining station, characterized in that a web-shaped semifinished product having a three-dimensional structure, a hollow profile and/or a multiplicity of recesses and/or holes in succession along its longitudinal edge is used as the at least one further web-shaped semifinished product which is fed to the joining station. An apparatus for carrying out the method is furthermore claimed.
