Abstract: In a method of fabricating an exhaust gas handling device, particularly an automotive emission control device, an insert, for example comprising a substrate and a support matting, is sensed as to its specific elasticity before it is clamped in place in an outer housing. For sensing, the insert is pressurized from without in a sensing station. Via the applied pressure and the displacement of the sensing tool the displacement of the insert at which it is to be clamped in place in the outer housing is determined. Then, the insert is fitted in an outer housing the inner dimensions of which correspond to the previously sensed wanted outer dimensions of the insert in the wanted compression.

The method includes the steps of introducing the insert piece into the outer housing and applying radial forces with clamping jaws which bear against the outer surface area of the outer housing and plastically deform the outer housing inwards in order to clamp the insert piece in the outer housing. The clamping jaws are configured to have edges such that marking lines are formed in the outer housing which do not continuously extend axially parallel to the outer housing along that portion of the outer housing in which the insert piece is arranged.

Abstract: A substrate assembly is stuffed into a converter outer shell to form a catalytic converter having a desired gap bolt density (GBD) value. The substrate assembly is formed by wrapping and taping a mat around a catalytic substrate. A predetermined pressure is applied to the substrate assembly and an outer diameter of the substrate assembly is measured at this predetermined pressure. A GBD value is predicted based on this measurement and if the GBD value is acceptable the substrate assembly is stuffed into the converter outer shell.
