Abstract
A method of producing an encased honeycombed body, in particular a supporting body of a catalytic converter, includes the steps of producing a honeycombed body by stacking and/or winding sheet metal layers, of which at least some are structured sheet metal layers, so that the honeycomb body has channels through which a fluid can flow. A sleeve is introduced into a tubular jacket. The sleeve is smaller in the axial direction than the axial length of the honeycomb body and the tubular jacket. The sleeve has an outer circumferential surface which substantially bears against a part of the inner wall of the tubular jacket. The honeycomb body is introduced into the tubular jacket and into the sleeve and is connected to the tubular jacket and the sleeve. If required, the tubular jacket may also be connected to the sleeve.
