<p>Since cutting edges (21) of two blades (19) forming a V-shape have different angles of inclination alpha , beta when viewed in the longitudinal direction of a wire (16), they come into contact with a resin coating (16A) at different timings while the wire (16) is being pushed in. When the resin coating (16A) is to be cut, the two blades (19) do not simultaneously come into contact with the resin coating (16A), but one blade first coming into contact therewith cuts it. Thus, a resistance during cutting can be small. <IMAGE></p> |
