    Patent number: 6220023
    Abstract: A flexible line element, particularly for exhaust pipes of internal combustion engines of motor vehicles, is disclosed having a screw thread-like or annularly corrugated bellows provided with cylindrical connection ends and a metal netting directly surrounding the bellows. The metal netting is inherently stable and has at least one plastic deformation for acoustic or mechanical damping of the bellows. Consequently, the metal netting has both a protective and a damping function.
