this case has a diameter 30 which is preferably in a range of from 70 to 130 mm fig6 shows a honeycomb body 1 which includes a plurality of stacks 9 disposed in the interior of the housing 4 in this case the stacks 9 have been wound about a plurality of winding locations 23 and introduced into the housing 4 fig7 diagrammatically illustrates a sequence of one configuration of the process according to the invention according to step 1 smooth sheet metal foils 3 and structured sheet metal foils 2 are layered alternately to form a stack 9 the smooth sheet metal foils 3 have a first length 8 and the structured sheet metal foils 2 have a second length 7 the stack 9 which is formed in this way is then bent about a winding location 23 with the aid of a tool 24 as is seen in step 2 one or more stacks 9 of this type are then at least partially introduced into a housing 4 in step 3 according to a variant illustrated in step 4 the stack 9 has not been completely introduced into the housing 4 but rather an uncovered end face has been brought into contact with a distributor 25 for distributing a bonding agent 14 due to the capillary effect the bonding agent 14 is sucked out of a reservoir 26 through the distributor 25 into the passages 10 in the honeycomb body 1 or stack 9 in accordance with step 5 the body 1 which has been prepared in this way is immersed in a fluidized bed 27 including brazing material 16 in the process the brazing material 16 penetrates.
