Abstract (en)
[origin: EP2568138A2] Flexible flat raw matrix (50), which is wound to a catalyst carrier (20), comprises at least two recesses, which are arranged adjacent to the raw matrix in a transverse direction, and are overlapped when viewed in the transverse direction. Independent claims are also included for: (1) a catalyst for purifying exhaust gases from an internal combustion engine, comprising the catalyst carrier, preferably a spirally wound flexible flat raw matrix; and (2) producing the above catalyst, comprising (a) providing the flexible flat raw matrix, (b) spirally winding the flexible flat raw matrix to the catalyst carrier, and (c) arranging the catalyst carrier in a casing tube (40).
