Abstract:
A method of making a metallic honeycomb carrier body comprising the steps of:providing a corrugated metallic foil strip having opposite side edges and obliquely oriented corrugations between the side edges;folding the corrugated foil strip on lines perpendicular to the side edges to provide a core body having fluid passages between opposite ends and a shaped periphery defined by folds in the corrugated strip;providing a metal jacket tube having an interior surface;inserting the core body into the jacket tube, the interior surface of the jacket tube engaging the periphery of the core body to be in compressive contact with the folds defining the periphery of the core body to deform the folds inwardly at the periphery of the core body; andjoining the periphery to the core body of the jacket tube.
