  • Sheet separation method and apparatus
    Patent number: 5535998
    Abstract: The front limit stop of the stack receiving magazine of a sheet separator is provided, in the region contacted by the lowermost sheets of the stack, with a retractable wall portion. The movements of this retractable wall portion are synchronized with the operation of a device which causes downward deflection of the edge region of a sheet located adjacent the magazine front limit stop. Accordingly, simultaneously with the application of the deflecting force, the frictional retaining force is removed from the edge region of the sheet to be separated.
