Abstract

A method for producing an exhaust-gas aftertreatment device inserts a monolith in a housing, assembled from a circumferentially enclosed jacket and two end funnels. The monolith is axially inserted into the jacket with a circumferentially enclosing support mat. The funnels are connected to the jacket via an axial connecting section shaped complementary to the cross-section of the jacket, such that each connecting section and an axial end section of the support mat axially overlap. The jacket, including the connecting sections of the funnels are reduced from a starting cross-section to an end cross-section. This produces a predetermined radial preload in the support mat in a support area extending from the one connecting section to the other connecting section to retain the monolith in the jacket.
