Abstract
An improved plate clamping assembly for a duplicating machine which utilizes a pivoted or cantilevered beam in the leading edge plate clamp assembly and a calibrated cocking screw to enabling skewing of the plate on the plate cylinder by moving one end of the pivoted or cantilevered beam. The improved assembly also coordinates the leading and trailing edge assemblies during installation of the plate by automatically adjusting the trailing edge plate clamp assembly to accommodate for an adjustment in skewing of the leading edge of the plate by the leading edge clamp assembly. Finally, it utilizes spring assemblies to enable self-adjustment for different plate thicknesses.
