Abstract

A method of manufacturing an exhaust gas carrying device, in particular an exhaust gas purification device, and a tool provided therefor include segment-like jaws that are used to deform an outer housing. The jaws have indentations or projections adjacent to each other, and which are complementary to form a continuously surrounding indentation/projection. The reshaped outer housing is provided with one or more surrounding projections or indentations by the deformation.
