Abstract
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 preformed to produce a weakened mid- section and then cured. The cured elastomer is then separated into two separate lengths of wiper blade by pulling the length of continuous elastomer along the weakened mid-section.
