Abstract
A catalyst carrier assembly for an automobile exhaust gas purifying device includes a smooth metal sheet and a pre-corrugated metal sheet wound alternately in a roll having a number of honeycomb convolutions. Each corrugation of the web-like pre-corrugated metal sheet is welded to the flat metal sheet at a plurality of points in the transverse direction during forming of the cylindrical roll. After forming the cylindrical roll, the cylindrical roll is heated so as to solder the web-like flat metal sheet and the web-like pre-corrugated metal sheet to each other at both of their end portions.
