Abstract: Method of fabricating and assembling metal catalytic converter catalyst substrates by sequentially laying strips of foil of predetermined widths onto a strip of sheet metal as the latter is formed into a single seam tube about the layers of foil to contain and restrain same, seam welding the tube along its length, and cross cutting the tube and contained layers of foil into predetermined lengths to form catalyst substrate units.
