Abstract
A bending device has a slot defined by facing side walls which taper from a reference plane in a direction to widen the slot proportionately with the slot depth to form two opposed facing bending edges. The angle the side walls taper from the reference plane is significant wherein each angle is within a range defined by a minimum value to assure the edges penetrate and sever the tab at its extremities and a maximum value to insure the tab is not completely severed during bending.
