Abstract
A trailing element device is disclosed for use in a headbox of a papermaking machine. The device includes a plurality of laminated sheets, the sheets being disposed within the headbox for dampening turbulence within the headbox. A binder cooperates with the plurality of sheets for binding the sheets together such that the trailing element device defines an upstream bead which extends in a cross-machine direction within the headbox. The bead is anchored within a slot defined by the headbox such that the bead is permitted to pivot within the slot so that a downstream end of the trailing element device is permitted to freely float within the headbox for attenuating the turbulence within the headbox. A wear resistant cladding is applied to the upstream bead for inhibiting wear and fracturing of the sheets caused by frictional engagement between the trailing element device and the slot.
