This invention relates to a machine and a method for forming a unitary structure from a first steel panel having an upturned flange and a second steel panel having a flat edge portion. The machine is comprised of a support surface for receiving the two panels in a nested relation. The support surface, holding the nested panels, is moved to a pre-hem position. The support surface then presses the flange of the first panel against a pre-hem flange engaging member to bend the flange to approximately 45° with respect to the plane of the first panel. The support surface moves the nested panels to a final hem position. The support surface then presses the flange against a final hem engaging member to bend the flange into full engagement with the edge portion of the second panel to form a unitary structure.
