Method of making a matrix for a catalytic reactor for the purification of exhaust gas

摘要

A matrix for a catalytic reactor for the purification of exhaust gas as well as a process and an arrangement for producing this matrix which has a corrugated metal strip, wound or folded, or a smooth strip and a corrugated metal strip that are wound or folded into several adjacent layers. The wound or folded layers are soldered together with one another. Radially extending indentations of small dimensions are provided at the points of the corrugated strip that border on the adjacent layers. In these indentations soldering material is received.
