An exhaust-gas conduction component that is effective as a vibration decoupling element and can be installed in an exhaust-gas system for conducting the exhaust gases of a motor vehicle internal combustion engine. The exhaust-gas conduction component () has an outer pipe () with a corrugated metal tube section () and an inner pipe () that is coaxial with the outer pipe () and separated from the latter by an annular gap. The outer pipe () also has a smooth central section (), first and second corrugated metal tube sections () and smooth first and second end sections (). The inner pipe () is permanently fixed to the outer pipe () by a continuous joint () extending around the central section () and the rectilinear exhaust-gas conduction component () is approximately axially symmetrical in relation to a central transverse axis (). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine.

A winding device for producing a field coil including a double-layer multiple-circuit winding for an electric motor includes a drive. The drive is configured to operate upon a winding mandrel with multiple lamellas arranged to be swung radially outwardly and inwardly by the drive in order to produce the double-layer multiple-circuit winding as a plurality of winding stacks that are arranged in separate slots and electrically connected in series, in parallel or both. At least two axially-separated winding stacks can be produced at the same time by the drive.
