ABSTRACT:
A hemming method for performing a 180 degree hem between an inner panel and outer metal panel. A curvilinear prehemming tool is then moved in a direction substantially parallel to the plane of the inner and outer panels so that the prehemming tool contacts a protruding coupon on the outer panel and creates a bend line in the coupon at a position spaced outwardly from the outer edge of the inner panel. Thereafter, a final hemming tool moves relative to the panels in a direction substantially parallel to the original plane of the inner and outer panels. This final hemming tool includes a first curvilinear surface which initially contacts the coupon and rolls the coupon such that the edge of the coupon contacts the inner panel. Thereafter, a generally planar wedge section of the final hemming tool contacts the coupon and compresses the coupon against the inner panel thus completing the hemming operation.
