ABSTRACT:
A method for manufacturing an exhaust gas treatment device for an internal combustion engine comprises axially inserting an exhaust gas treatment cartridge into a casing, wherein the casing has an initial inside cross-section that is larger than an outside cross-section of the exhaust gas treatment cartridge. A funnel is axially inserted into an end region of the casing, wherein an outside cross-section of the funnel is smaller than the initial inside cross-section of the casing. The cross-section of the casing is subsequently reduced such that the casing ultimately has a first ultimate inside cross-section that is equal to the outside cross-section of the exhaust gas treatment cartridge in a region, in which the at least one exhaust gas treatment cartridge is arranged, and a second ultimate inside cross-section that is equal to the outside cross-section of the funnel in the respective end region, in which the respective funnel is arranged.
