<p>This invention relates to improved apparatus for sawing stone blocks. A number of rotary saw blades are arranged in series in the cutting plane of the blades with the cutting depth of each blade being successively deeper to cut the blocks to a predetermined depth. Each block is fed past the blades on a work carrier truck and after it is partially cut, reversing apparatus turns it over on the truck. The truck is then again passed by the rotary blades and the cut is completed from the other side of the block. This has the advantage of reducing the depth of each cut and thus speeding up the cutting operation.</p> |
