Abstract: A wiper blade for endless conveyor belts has three basic components or features which improves blade performance over the prior art. These components include:1. a multiradius side profile having a concavity defining the torsion resistance point,2. a thicker base section, and3. a high profile metal mounting insert.These three components act together to substantially reduce the bending moments associated with wiper blade operation and provide an improved structural profile with a high moment of inertia and shorter effective column length. These structural improvements allow the use of softer and more wear-resistant elastic polymers without the risk of blade buckling. The multiradius concave side profiles allow the use of a short thin blade tip profile which transitions to the thicker, ridged base profile. The bending moment generated by the operational forces is now resisted primarily at the transition point of the two profiles, e.g.
