ABSTRACT:
A method for making a honeycomb carrier body and product formed thereby in which a corrugated foil strip is provided having opposite side edges and corrugations oriented at an oblique angle to the side edges. The corrugated foil strip is folded on lines perpendicular to the side edges to provide a core body having fluid passages between opposite ends and a shaped periphery defined by parallel outside folds in the corrugated strip. The core body thus formed is inserted into a jacket tube so that folds at the core body periphery are in compressive contact with the jacket tube, and the periphery of the core body is joined to the jacket tube. Preferably, the corrugated foil strip is coated before the folding step, such as with an oxide layer, a catalytic coating or both, prior to the folding step. The periphery of the folded core body is then cleaned such as by grit blasting to remove the coating and reveal a clean metallic surface at the outside folds of the foil strip before the body is inserted into the jacket tube.
