The method involves extruding an elastomer utilized for forming a wiper by using an extrusion tool, and vulcanizing the elastomer. The extrusion tool is realized such that a side (15) adjacent to a rectangular wiping edge (11) is formed with a concave curvature to form the edge with an acute angle (alpha) immediately after extrusion, where the acute angle ranges from 10 degree to 89.9 degree. Another edge is placed opposite to the formed rectangular edge and is rectangular in shape such that a wiping strip (1) has rectangular termination. |
