Abstract
A blank for the production of a catalyst carrier body includes spirally-wound alternating layers of smooth and corrugated metal sheets. At least one of said corrugated sheets forms an innermost layer defining a coil-free central zone surrounded by said innermost layer. A jacket is added around the blank to form a catalyst carrier body. The sheets are wound on a toothed roller.
