A method is shown for forming a wiper blade in which a continuous length of elastomer is extruded through a die having a die opening shaped to produce a pair of wiper blades joined in edge-to-edge relation. The elastomer is scored in the mid-section thereof to produce a score line and then cured. The scored and cured elastomer is then separated into two separate lengths of wiper blade by dividing the length of continuous elastomer along the score line. |
