Abstract:
A tool and method of hemming a panel wherein the tool engages a flange to apply a compressive force with a stop initially preventing a distal end of the flange from moving inwardly. The hemming tool bends the intermediate portion of the flange between the flange bend and the distal end toward the panel. The stop is withdrawn to allow the flange to be progressively formed toward the panel until the distal end is aligned with the intermediate portion.
