摘要 |
A honeycomb body has a plurality of at least partially structured sheet metal layers forming a plurality of passages through which a fluid can pass. The sheet metal is plastically deformed in a region of a mandrel passage whose cross-section is substantially determined by a mandrel of a winding device with which the honeycomb is formed. The free flow cross-section of the mandrel passage is closed at least in a portion of the passage along the flow direction by deforming the sheet metal with a deformation punch. The deformation punch has an end portion with a sharp-edged rim. |
