    摘要: A honeycomb body includes an inlet end side and an outlet end side. Metal sheets are wound, intertwined and/or layered into a multiplicity of sheet metal layers being at least partially structured to form channels leading from the inlet end side to the outlet end side. Edges of at least some of the sheet metal layers have cutouts formed therein at the inlet end side and/or the outlet end side, resulting in a fissured structure of the inlet end side and/or the outlet end side. As a result, only the smooth metal sheets or only the structured metal sheets or both can be provided with the cutouts. Additionally, at least some of the metal sheets can be made of a porous material, in particular compressed metal fibers. Deposition of soot particles on the end sides of the honeycomb body is, to a large extent, prevented due to the cutouts.
