ABSTRACT:
A carrier matrix for use in the manufacture of a catalytic reactor for the purification of exhaust gases in an internal combustion engine of a motor vehicle is prepared by joining in wound form a corrugated steel sheet and a generally flat steel sheet, the sheets being joined in locations where they contact one another by the use of solder or brazing material. In one embodiment solder is applied in spots along the tops of the arches of the corrugated sheet, and after coiling the solder is activated by heating. In another embodiment, coiling is first carried out and then soldering is accomplished by the application of solder into one or both end faces of the coil.
