ABSTRACT:
A process for preparing catalytic converters, especially bodies of motor vehicle catalytic converters of modular design, by pushing monoliths and a surrounding support jacket into prefabricated tubes, whose cross section essentially corresponds to the profile of the monolith plus an addition for the support jacket. The dimensions of the tube (housing) are adapted to a constant gap (s) from the monolith by sizing (calibrating) the prefabricated tubes which initially have a smaller cross section.
