Abstract
A metallic catalyst carrier body for the cleaning or treatment of an exhaust-gas flow, in particular of small engines, includes a multiplicity of strip-shaped foils which are joined together in the form of a honeycomb structure. The foils form a foil assembly structure in which mutually adjacent respective foils are securely interconnected at connecting locations that are spaced apart from one another and offset alternatingly relative to one another. If the foil assembly is stretched, for example by winding the same into a hollow body, the honeycomb structure is formed, defining flow channels with at least one radial directional component in its interior, through the use of cells. A foil assembly structure which is also provided is suitable for use as a catalytic converter, in particular for small engines, by virtue of the fact that the foil assembly structure, which forms an initially essentially flat flexible honeycomb structure during stretching, can be wound into virtually any cross-sectional form of a hollow body and consequently can be adapted to existing exhaust pipe casing configurations. A method for manufacturing a metallic catalyst carrier body is also provided.
