  • Variable thickness set compensation for stapler
    Patent number: 4421264
    Abstract: A stapler mechanism for fastening variable thickness documents includes a stack receiving receptacle disposed between the head/hammer assembly and the clinching or anvil assembly of said stapler. A sensing device is coupled to the stapler mechanism and generates control pulses indicative of relative motion between the head/hammer assembly. A controller processes the signals and generates control signals which vary the stroke and the force driving the hammer and returns the head/hammer assembly to its home position following a stapling cycle.
