Abstract
A method of producing a honeycomb body including a stack of structured metal sheets disposed in layers at least partially spaced apart from each other defining a multiplicity of channels through which gases can flow, the stack having ends twisted in mutually opposite directions about at least two fixation points, and a jacket tube surrounding the sheets and being formed of at least one segment, the sheets having ends joined with the jacket tube.
