Abstract

A method for uniting an exhaust treatment body (2) surrounded by a bedding mat (6) with a metal case (8) forming a housing for the exhaust treatment body, characterized in that one or two preformed metal blanks are pressed by means of a form tool (10) against the exhaust treatment body (2) surrounded by the bedding mat (6) and thereby brought into the final case form; and the thus formed metal blank or blanks are welded to the case (8) along one or two longitudinal seams (28). An afflux funnel (44) and a discharge funnel are preferably welded on by means of a special triple seam (56).
