发明名称 METHOD AND APPARATUS FOR HEMMING PANELS TOGETHER
摘要 <p>Method and apparatus hems the edges of inner and outer panels by bending a peripheral flange of the outer panel over edge portions of the inner panel to form a panel assembly. A press apparatus has a lower platen and an upper platen. The outer panel is placed onto the lower platen and the inner panel is placed onto the lower panel with the peripheral flange of the outer panel surrounding the inner panel. The upper platen is lowered to capture the inner panel atop the outer panel. A first portion of the peripheral flange is hemmed by closing hemming dies over the first portion of the peripheral flange to bend the flange onto the inner panel. A second portion of the peripheral flange is hemmed by passing a hemming roller mechanism along the second portion of the peripheral flange to bend the flange onto the inner panel.</p>
