Patent ID: 7171747

Claim:
A method for producing a honeycomb body having a predetermined number of sheet metal layers from at least one supply roll, at least some of the sheet metal layers being at least partially structured sheet metal layers having structures making it possible for a fluid to flow through the honeycomb body, the honeycomb body having an interior with a predetermined cohesive free volume for receiving a measurement sensor, which comprises the steps of: a) selecting a section of a sheet metal strip from the supply roll for forming a sheet metal layer of appropriate size; b) identifying the sheet metal layer; c) reading at least one associated hole position and at least one associated hole edge from a memory to be formed in the sheet metal layer; d) constructing at least one hole with the hole edge in the sheet metal layer at the at least one associated hole position, identifying whether or not the sheet metal layer is to be corrugated, and corrugating at least a portion of the section of layers to be corrugated; e) identifying a section to be separated from the supply roll and separating any section identified as a section to be separated from the supply roll; f) repeating steps a) to if) for forming a predetermined number of the sheet metal layers; g) identifying whether or not the predetermined number of sheet metal layers need stacking and stacking the predetermined number of the sheet metal layers corresponding to an identification of the sheet metal layers of layers that need stacking; h) identifying a number of sheet metal stacks that are needed and repeating steps a) to h) for producing the number of sheet metal stacks; i) winding at least one of the sheet metal layer and at least one of the sheet metal stacks to form a honeycomb structure with smooth and corrugated sheet metal layers forming channels through which a fluid can flow; j) introducing the honeycomb structure into a casing tube; k) introducing the measurement sensor at a predetermined position into the honeycomb structure and the casing tube; and l) carrying out the steps d) and e) in any desired sequence order.
