ABSTRACT:
There is provided a novel core member for use in a catalytic converter characterized by a corrugated nonnesting thin metal foil having a given length and a given width, which strip is overfolded to provide portions of about equal length. Along the fold line is attached a wire or rod, as, for example, by welding. The wire containing ends are gathered and secured to form a central core. This core may by spirally wound to fit within a peripheral housing, and the free ends of the core members secured to the housing, as by welding. This assembly may be used in a catalytic converter and may be equipped to be electrically heated from a battery using the resistance of the corrugated thin metal strip portions to effect heating thereof.
