METHOD OF MANUFACTURING FOR WIPER BLADE

摘要

PROBLEM TO BE SOLVED: To reduce the costs of dies by using extruded blade rubber. SOLUTION: The wiper blade manufacturing method comprises the first step of manufacturing an extrusion having a blade rubber body 9a, an anti-flip neck portion 9d, a wiping-surface pressure contact portion 9i and a portion 9i4 to cut away, the second step of cutting the extrusion manufactured in the first step into preset longitudinal lengths, and the third step of cutting the cut portion 9i4 integral with a vertex 9i3 of each wiping-surface pressure contact portion 9i away from the vertex 9i3.
