Method for Generating Openings in a Metal Foil, Method for Producing a Honeycomb Body, Exhaust Gas Treatment Unit Having a Honeycomb Body Produced by the Method and Motor Vehicle

摘要

A method for generating openings in a metal foil includes at least the following steps: a) providing a planar metal foil, b) generating at least one bend in the metal foil, and c) generating at least one opening in the region of the at least one bend through the use of a cutting production process. Grinding tools are preferably used. A method for producing a honeycomb body, an exhaust gas treatment unit for mobile internal combustion engines having a honeycomb body and being produced by the method, as well as a motor vehicle, are also described.
