ABSTRACT:
A method and apparatus for assembling an exhaust treatment device such as a catalytic converter employs post calibration to achieve a desired bulk gap density of a support mat surrounding a substrate in the device housing. The mat is gauged under pressure to a thickness yielding the target bulk gap density and the pressure is saved for use in comprising the device housing against the mat after soft stuffing of the mat/substrate subassembly into the housing.
