Abstract:
1. A method for manufacturing a catalytic-converter carrier element, which comprises: manufacturing at least one stack with a plurality of alternately disposed sheet metal layers having layer ends; shaping the at least one stack to form a metallic honeycomb element with a cylindrical shape, the cylindrical shape of the honeycomb element being formed by the layer ends, the sheet metal layers being structured to form cells through which a fluid can flow; providing a tool with an inlet cross-section and outlet cross-section different from the inlet cross-section; and deforming the honeycomb element to produce an external shape different from the cylindrical shape by guiding the honeycomb element at least partially through the tool from the inlet cross-section towards the outlet cross-section.
