<p>The mud flap has an additional corrugated grille (8) sandwiched between a solid panel (6) and a first grille (7) which form a water draining channel. The crests of the corrugated grille are in contact with the first grille and solid panel alternately, to which they are attached, forming parallel ducts (17). The mesh holes in the two grilles are smaller than the distance between the first grille and the solid panel; they are oblong in shape, with their longer dimension lying perpendicular to the corrugations. Both grilles and the solid panel are made from a synthetic material which is flexible and can be heat-welded.</p> |
