A method of producing a metallic exhaust gas catalyst carrier body includes winding alternating layers of smooth and corrugated sheetmetal strips to form a blank and inserting the blank into a jacket tube, each winding of the blank being formed of a respective smooth and corrugated sheetmetal strip each having an individually predeterminable length; determining the length of each winding in accordance with the length necessary for filling a predetermined jacket tube cross section, fixing each winding beforehand to at least one side of the blank, so as to produce an approximately egg-shaped blank which is tightly wound on the one side and wound with varying looseness in the remaining region thereof; inserting the blank into the jacket tube in such a manner that the tightly wound side is located in a region of the jacket tube cross section in which a largest possible inscribed circle of the jacket tube cross section engages the jacket tube, and a device for carrying out the method, a carrier body formed by the method and device, and a blank forming part of the carrier body.
