Patent ID: 7111393

Claim:
A process for producing a metallic honeycomb body, which comprises the following steps: providing metal foils and forming a void in at least one of the metal foils; forming voids in adjacent metal foils with mutually different dimensions; subsequently forming the metal foils for at least partially providing structures on the metal foils; processing the at least partially structured metal foils by stacking and subsequently winding the metal foils in an S shape or arranging the metal foils to run in an involute form from an inside outward, to form a honeycomb structure with passages defined by the structures on the metal foils for conducting a gas therethrough, and to place the at least one metal foil such that the void defines a receptacle extending into an interior of the honeycomb structure and being configured to receive therein a sensor device; providing a tubular casing with an opening and introducing the honeycomb structure into the tubular casing, with the opening at least partly aligned with the receptacle; connecting the metal foils and the tubular casing with a suitable joining technique; and integrating a sensor in rod form into the receptacle without the sensor making contact with the metal foils.
