Disclosed is method of manufacturing catalytic converters having a ceramic honeycomb (14) surrounded by a supporting mat (24) and located within a housing, comprising the following steps: (1) forming a cylindrical metal shell (12) exhibiting a uniform curvature and having a lap joint (30) exhibiting substantially the same curvature as the outer surface (28) of the metal shell; (2) wrapping the honeycomb in a sufficient amount of supporting mat material and inserting the wrapped honeycomb into the metal shell; (3) compressively closing the metal shell around the wrapped honeycomb thereby creating a substantially uniform compressive stress on the honeycomb by the supporting mat. <IMAGE> <IMAGE> |
