Abstract
A method for producing metallic sealing and stopper elements for flat gaskets by winding or rolling at least one metallic, sheet metal- or foil-like base body to obtain a tube as an intermediate product, bringing the mutually opposing end regions or parts, or the entire contact surface of the tube, into operative connection with each other by way of bonding, non-positive or positive joining techniques, or combinations thereof, contouring the tube or tube sections generated therefrom at least in some regions, and severing at least one annular or disk-shaped component in order to generate a sealing or stopper element in the contoured region of the tube or tube section.
