Abstract
A method for producing a honeycomb body having a housing and a honeycomb structure with a multiplicity of channels includes: providing a smooth metal sheet, forming a structure into regions of the smooth metal sheet, the structure in one longitudinal portion is formed differently than a structure in a second longitudinal portion of the metal sheet, forming the honeycomb structure by arranging and winding the structured metal sheet, such that a first cell density in an inner radial zone is increased in relation to a second cell density in an outer radial zone, inserting the honeycomb structure into the housing and, connecting the honeycomb structure to the housing.

A method for producing a honeycomb body for exhaust-gas aftertreatment, comprising:
- providing at least one smooth metal sheet;
- forming structures into at least partial regions of the at least one smooth metal sheet, wherein a first structure in at least one first longitudinal portion of the metal sheet is formed differently than a second structure in at least one second longitudinal portion of the metal sheet;
- forming a honeycomb structure with a multiplicity of channels by arranging and winding the at least one partially structured metal sheet, wherein the metal sheet is arranged and wound such that a cross section of the honeycomb structure has a first cell density in an inner radial zone that is increased in relation to a second cell density in an outer radial zone;
- inserting the honeycomb structure into a housing;
- and
- connecting the honeycomb structure to the housing.
