  • Hemming machine
    Patent number: 6584661
    Abstract: A hemming machine has a single bending block having a surface for carrying out a preliminary bending process and another surface for carrying out a final bending process, a lower block for placing an outer panel with a flange and a mechanism for moving the bending block. The mechanism moves the upper deck in an arcuate way around a specified axis such that a force with a relatively large horizontal component is applied to the flange of the outer panel when the preliminary bending surface of the bending block bends the flange in the preliminary bending process, and then in another arcuate way around another axis such that a force with a relative large perpendicular component is applied to the flange of the outer panel when the final bending surface of the bending block bends the flange in the final bending process.
