Abstract: A flange bending apparatus for bending an upstanding flange on an inside perimeter of an automotive window opening. A flanging steel drive reciprocally drives a flanging steel between retracted and extended positions on a frame. The retracted position of the first flanging steel allows a metal panel workpiece to be positioned on the frame with the flanging steel extending through an opening in the workpiece. When in the extended position the flanging steel overlies a portion of an inside perimeter of the opening. As it moves toward the extended position the flanging steel engages an inner surface of an upstanding workpiece flange that extends upward from around the inside perimeter of the workpiece opening. The flanging steel then bends the flange radially outward as the drive continues to move the steel to the extended position. The flanging steel bends the workpiece flange radially outward such that a lateral bend line is formed along the flange where no breakline was present before bending.
