Abstract: A process for producing a structure in a smooth sheet-metal strip includes multiple process steps. In a first step, a first section of a smooth sheet-metal strip is fed to a first tool and a second section of the sheet-metal strip is fed to a second tool in a direction of advance. Then the sheet-metal strip is stopped. A sheet-metal machining of the first section of the sheet-metal strip is carried out using the first tool. A sheet-metal machining of the second section of the sheet-metal strip is carried out using the second tool, with the first feeding step being carried out simultaneously. An apparatus is provided for producing a sheet-metal strip of such a complex structure, which produces the structure with a very high degree of accuracy even when the materials properties differ.

Abstract: An apparatus for deforming a jacket tube of a honeycomb body includes a plurality of radially displaceable segments each having a sliding surface with a wedge-shaped cross section. At least one annular, axially displaceable closing element surrounds the segments and has at least one oblique surface sliding on the sliding surface. An actuating device connected to the closing element has an annular shape defining an opening through which the honeycomb body with the jacket tube can enter from one side and exit from the other side. A method for deforming a jacket tube on a honeycomb body includes passing the honeycomb body with the jacket tube through at least one tunnel-like calibrating station in which the jacket tube is deformed. A transport direction of the honeycomb body and the jacket tube during a production process is maintained during the deformation.
