Abstract
A longitudinally and radially formable wing tip lagging that can be formed to match non-linear wing tip profiles. The longitudinally and radially formable wing tip lagging serves as a wear surface that can be replaced as it is worn rather than wearing down the ferrous or non-ferrous wing tips permanently affixed to the outermost positions of the wing pulley. The wing tip lagging includes a backing plate and a sacrificial stratum. The backing plate is the primary structural component and it includes a plurality of bending features that facilitate both longitudinal and radial forming of the wing tip lagging. The bending features may include a plurality of notches or slots formed along the backing plate. For example, the notches may be arranged in a regular repeating pattern along the length of the backing plate.
Claims16
A method for installing wing tip lagging onto a wing of a wing pulley, comprising the steps of:
- providing a wing tip lagging with a plurality of bending features, the bending features being further defined as a notch, a slot or another absence of material;
- fitting a starting portion of the wing tip lagging onto the wing;
- forming the wing tip lagging directly onto the wing by bending the wing tip lagging to match an underlying shape of the wing using the wing as a forming fixture, the forming being facilitated by the bending features;
- and
- securing the wing tip lagging in place on the wing;
- wherein the wing tip lagging includes a backing plate having a web and a pair of sidewalls extending from the web to define a mouth fitted over the wing, the bending features being disposed in the sidewalls.

A method for installing a wing tip lagging onto a wing tip of a wing pulley, comprising the steps of:
- providing a wing tip lagging, the wing tip lagging having a generally U-shaped backing plate with a main beam and a pair of flanges extending from the main beam in spaced-apart relation, the flanges cooperatively defining a mouth having a width sufficient to fit over the wing tip, each of the flanges including a plurality of bending features, each bending feature being defined by an absence of material;
- fitting a starting portion of the wing tip lagging onto the wing tip;
- forming the wing tip lagging directly onto the wing tip by bending the wing tip lagging to match an underlying shape of the wing tip using the wing tip as a forming fixture, the forming being facilitated by the bending features;
- and
- securing the wing tip lagging in place on the wing tip.
