ABSTRACT:
A catalytic converter includes a metal honeycomb catalyst support which is anchored in a canister so that it cannot telescope or blow out. The honeycomb catalyst support is made by folding a strip of metal back and forth upon itself. The lines of folding are inclined to the perpendicular to the axis of the strip. The repeating sequence of the inclinations is left, right, right, left, etc. Folding the strip in this manner produces a honeycomb that has a taper in both of two directions so that it can be anchored in the canister. The canister has a taper which coincides with the taper of the honeycomb. The invention also includes a method and apparatus for making crease lines on the strip, so that the strip can be folded.
