Abstract
A metal catalyst carrier body includes first and second differently corrugated sheet-metal layers being alternatingly wound defining conduits therebetween through which gas flows. The first sheet-metal layer has a simple first corrugation with a periodicity .lambda..sub.1 and an amplitude A.sub.1 primarily determining the size of the conduits. The second sheet-metal layer has a second corrugation with a periodicity .lambda..sub.2 and an amplitude A.sub.2. .lambda..sub.2 =(n..lambda..sub.1)/m, where n=1, 2 or 3; m=1, 2, 3, 4, 5 or 6; and m is .gtoreq.n, forming a multiplicity of periodically recurring oculating contact points having the same direction of curvature. Considering the shape and periodicity of the corrugations, the amplitude A.sub.2 is smaller than the amplitude A.sub.1 by at least an amount sufficient to cause the curvature of the first sheet-metal layer at the contact points to be at least substantially as large as the curvature of the second sheet-metal layer at the contact points.
