Abstract
An improved honeycomb body having a perimeter which encloses the cross section of the honeycomb body. The honeycomb is formed by folding a strip of metal foil back and forth upon itself to provide folds, the foil having corrugations whereby the corrugations maintain the spacing between the folds. One end and only one end of each fold terminates on the perimeter of the body, the cross section of the body being completely filled with folds. The honeycomb body has increased structural and mechanical integrity and is especially useful as a catalyst support for preparing an automotive catalyst.
