  • Modular guillotine
    Patent number: 6460534
    Abstract: A known stone cutter having an upper jaw powered for a guillotine type cut has a transverse bar in the upper jaw. A series of cube shaped cutter units are mounted side by side along the transverse bar. An isostatic manifold connects all the cutter units for contouring the cutter jaws to the irregular rock surface. At cut time each cutter unit is hydraulically isolated via a shuttle valve from the isostatic manifold so as not to transmit huge cutting pressures to the isostatic manifold and unused cutter units in that cut.
