Claim:
A method for producing a honeycomb body for an exhaust gas treatment unit, the method comprising the following steps: applying brazing material to an at least partially structured metal foil by: a) providing at least one flat metal foil; b) shaping the at least one metal foil to produce a structure by reciprocating punching with a clock frequency; c) applying brazing material to the at least one metal foil with the same clock frequency as the shaping of the at least one metal foil; and carrying out steps b) and c) discontinuously and at least partially together; placing the brazing material in contact with sections of at least one metal foil before twisting or winding the at least one metal foil to form at least one honeycomb structure of the honeycomb body of the exhaust gas treatment unit; fixing the at least one honeycomb structure; and brazing the at least one honeycomb structure.
