ABSTRACT:
Apparatus for gripping slabs of stone and supporting the slab on its edge while it is cut into two planar laminae, comprises grippers in the form of oppositely arranged vacuum-operated suction cups which grip opposite faces of the slab to prevent relative movement of the partly-cut stone laminae during cutting thereof. One of the grippers is mounted for bodily vertical swinging movement toward and away from the slab about an axis disposed no higher than the lower edge of the slab.
