Abstract
A bending and hemming apparatus configured to both bend and hem a sheet metal panel to form a body closure member at a single station. The apparatus includes a hemming machine movable between a retracted position spaced from a bending machine and advanced positions adjacent the bending machine to assist in the bending operation and to hem the body panel into a finished product. The apparatus also includes an anvil assembly pivotably supported on the hemming machine. The anvil assembly is movable between a lowered position where it engages the workpiece when the hemming machine is advanced to a bending position adjacent the bending machine. In the lowered position, the anvil assembly provides a fulcrum around which the workpiece is bent. The anvil assembly is pivotable to a raised position to allow the hemming machine to be advanced to a hemming position adjacent the bending machine from which the hemming machine can engage the bent workpiece to hem the workpiece.
