Method of forming an improved wiper blade. |
摘要 |
<p>A method is shown for forming a wiper blade in which a continuous length of elastomer (11) is extruded through a die (17) having a die opening shaped to produce a pair of wiper blades joined in edge-to-edge relation. The elastomer (11) 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.</p> |
