Beschreibung
Zusammenfassung:	A honeycomb body for the aftertreatment of exhaust gases from an internal combustion engine formed from a plurality of metal foils which are stacked on one another to form a layer stack and are wound around at least one center of rotation. The layer stack is formed alternatingly from smooth and at least partially structured metal foils, the metal foils have a foil width and a foil length. The width of the foils runs along the main throughflow direction of the honeycomb body from a gas inlet side to a gas outlet side, and the foil length runs transversely to this direction, wherein at least some metal foils have at least some slots which divide the respective metal foil into a plurality of segments.
