Title: Apparatus for bending cutting blade

Abstract: An apparatus for bending a cutting blade rule includes: a guide having a guide passage formed therein for transferring said cutting blade rule in a lengthwise direction; a first rotary body located at an upper position adjacently to a head of said guide; a second rotary body located at a lower position adjacently to a head of said guide and oppositely to said upper position; a first bending member supported by a hole formed on said first rotary body; a second bending member supported by a hole formed on said second rotary body, said second bending member being opposite to said first bending member in a substantial perpendicular direction to said lengthwise direction; a drive means for driving said first and second rotary bodies; and linear drive means for linearly moving said first and second bending members respectively. Accordingly, independent forces can be applied to each upper and lower portions of the cutting blade rule, which forces are adjusted based upon predetermined sizes of the cutting blade such as height and thickness and in particular physical property thereof, thereby eliminating or minimizing drawbacks caused by spring back effects and forming the cutting blade into desirable precise profiles.
