1. A hemming machine for hemming the beltline hem and the outside perimeter hem of a vehicle door panel, the hemming machine comprising: a pressure plate that is actuated by a force from a press, a beltline hemming tool and an outside perimeter hemming tool, both of which are driven by the pressure plate, a first actuator that is driven by the pressure plate and is arranged to drive the beltline hemming tool into the beltline hem flange and to bend the beltline hem flange from an Open position to a Pre-Hem Complete position, a second actuator that is driven by the pressure plate to drive the beltline hemming tool into the beltline hem flange and to bend the beltline hem flange from a Pre-Hem Complete position to a Final-Hem Complete position, and a third actuator that is driven by the pressure plate to cause the outside perimeter hemming tool to bend the outside perimeter flange from a Pre-Hem Complete position to a Final-Hem Complete position, whereby the third actuator positions the outside perimeter hemming tool relative to the outside perimeter flange such that the outside perimeter hemming tool does not bend the outside perimeter hem to the Final Hem Complete position until after the beltline hem flange is bent to the Final Hem Complete position.
