Patent abstract
A bending apparatus is provided with a ram start-up device so as to be movable in a lateral direction. A controller moves the ram start-up device to a point in front of positioning points of abutments corresponding to points of selected edges of a workpiece. The bending apparatus includes a foreign object detector that detects the entry of a foreign object into a region of movement of the ram start-up device. A controller prevents the ram start-up device from moving when the entry of the foreign object is detected.
