Claims
- 1. In a method of gauging a slab of granite or hard stone by advancing said slab on a conveyor belt and subjecting said slab to a chuck carrying a diamond covered tool, said chuck being capable of inverting the direction of its motion, said tool carrying out a transversal and alternating motion with respect to the direction of advance of the slab, the improvement which consists of the steps of:
- 1) said chuck moving only in a direction perpendicular to the direction of advance of the slab;
- 2) advancing said slab on said conveyor belt in a discontinuous manner and while the slab is still, gauging a first band of said slab along the entire width thereof by causing the chuck and the tool carried thereon to perform a motion which is transversal to the direction of advance of the slab, wherein said tool has a width equal to the width of the slab and has an axis of rotation which is parallel or perpendicular to the direction of advance of said slab;
- 3) then halting said gauging and advancing the belt of a distance equal to the width of said slab and inverting the motion of the chuck, 4) gauging a second band of the slab parallel to said first band while the slab is still, whereby said chuck operates on a second band of said slab, said second band being parallel to said first band, and repeating said steps (1), (2) and (3) and (4) whereby said tool performs a fret-shaped path.
