Abstract
There is provided a substantially nonnesting corrugated catalytically active thin metal foil suitable for making a monolith which when encased in a housing and inserted in the exhaust line, e.g., an automobile exhaust line, will remove pollutants in the exhaust. The device is rendered substantially nonnesting by forming the corrugations according to guidelines and which corrugations are perpendicular to the longitudinal marginal edges of the metal foil. The pressure drop through the device is thus minimized and the necessity for a flat foil co-laminate is avoided.
