Headbox trailing element.

摘要

@ A paper machine trailing element (11) for use in a slice in a headbox wherein the trailing element is formed of laminations with a bead at the upper end for anchoring the element (11) in a slice chamber with the bead formed of laminations with fibers on the outer surface in the machine direction and in the cross-machine direction within the bead so that the element (11) has a greater stiffness in the machine direction at the upstream end (18) with the element (11) tapering to a thin tip (19) at the downstream end and the downstream end formed of laminations (24, 27) with fibers extending in the cross-machine direction for a greater stiffness to minimize instability.
