ABSTRACT:
A catalytic converter of the automotive type comprising a reduced central oval section that compresses a support mat around a catalyst substrate, the reduced central section comprising radially inwardly biased ribs that are parallel to the longitudinal axis of the converter.
The converter can be made by inserting a catalyst substrate and surrounding support mat through the open end and into the central portion of an oval sheet metal tube, after which the reduced section and longitudinal ribs are formed in the central portion of the tube to compress the mat and securely engage the substrate, and the ends of the tube are pinched together to form sealed end closures with gas flow passages therein.
