Abstract
A mechanism for hemming the beltline of a vehicle door panel is combined with a mechanism for hemming the outside perimeter of the door panel, and the two mechanisms are driven by a common drive. The beltline hemming steel acts on the beltline hem before the outside perimeter hemming steel acts on the outside perimeter hem, and lost motion in the actuation of the beltline hemming steel allows the beltline hemming steel to complete the beltline hem before the outside perimeter hem is completed. The lost motion mechanism provides reduced interaction or sensitivity between the steels, and the delay in the completion of the outside perimeter hem allows the entire hemming apparatus to be more easily tuned during set-up. The lost motion allows the entire mechanism to be less sensitive to variations in workpiece thickness.
