Method for producing an annular honeycomb body, and annular honeycomb body

摘要

A method for producing a honeycomb body includes providing an annular radial partial region with channels through which a fluid can flow. The honeycomb body is formed from at least one metallic layer fastened at least at one fastening point to an outer casing tube. Each metallic layer has alternating substantially smooth and structured sections folded onto one another. A honeycomb body is also provided. The method and the honeycomb body advantageously permit an annular honeycomb body with low material expenditure and good durability to be produced.
