The invention relates to a honeycomb body (13) that is configured from alternating layers that are essentially smooth (10) and layers that are at least partially structured (1), in particular a catalytic converter support and/or filter, preferably for the exhaust gas system of a motor vehicle. According to the invention: the layers (1, 10) form cavities (13) that allow a fluid to permeate essentially in an axial flow direction (19); the structured layers (1) have structural extremities (4, 5), which are in contact with essentially smooth neighbouring layers (10); and the structured layers (1) comprise inverted sections (2) in the vicinity of their structural extremities (4, 5), said sections protruding into the cavities (12) and having a form that is approximately the inverse of that of the structural extremities (4, 5) in a cross-section through the honeycomb body (13) that runs perpendicularly to the flow direction (19), in such a way that breaks (22) are formed in the structural extremities (4, 5) in the vicinity of the inverted sections (2). Counter-structures are configured (11) in the vicinity of the inverted sections (2) and/or the structural extremities (4, 5) in the essentially smooth layers (10), said structures engaging with the structural extremities (4, 5) and/or the inverted sections (2), in particular in a positive fit. In the inventive honeycomb body, (13) relative displacements of the two layers (1, 10) in the flow direction (19) are prevented by the co-operation of the inverted sections (2) and the counter-structures (11) that are allocated to the latter, by the engagement of the counter-structure (11) with the inverted section (2). This also prevents the telescoping of honeycomb bodies. |
