Abstract
A catalytic converter is constructed by assembling a plurality of non-nestable foil leaves, each having opposite proximal and distal ends defining a leaf length. The proximal ends of the foil leaves are interconnected to provide a continuous flexible strip of overlapping foil leaves in which the distal ends of the leaves extend freely. The strip of foil leaves is subsequently formed to arrange the leaves to lie in curved paths radiating inwardly from the interconnected proximal ends toward a central area.
