ランクを折曲げることを特徴とする折曲げ機。 A bending machine that bends the front edge of a blank held by a blank holder into a desired shape by a bending blade that moves in close proximity to the blank holder in a substantially orthogonal direction, the bending arm having the bending blade attached to its tip. The base end of the rocker arm is swingably attached to the bending machine body via an eccentric member, and an actuator is provided that rotates the eccentric member to displace the entire rocker arm in the horizontal direction, while simultaneously acting in opposite directions. A folding machine characterized in that the tip side of the rocker arm is supported from above and below by a double-acting actuator, and the double-acting actuator is simultaneously driven to swing the rocker arm and bend the blank.
