A hemming assembly and method for joining the edges of a pair of panels together includes a main die supporting edges of the two panels, a pre-hem slide supporting a pre-hem tool, a final die holder supporting a final die, and at least one drive to move the tool and die for pre-hemming and final hemming, respectively. A mechanism guides the pre-hem slide first vertically for at least partial pre-hemming, and then at an angle to expose the pre-hemmed edges for final hemming. Vertical travel of the pre-hem tool against the edges produces a superior and less distorted joint, and pre-hemming and final hemming can be performed in one overall stroke. A number of assemblies can be arranged to pre-hem and final hem a number of edges.
