ABSTRACT:
A stone cutting belt includes a flexible and continuous main body with length and lateral width, having a top surface and a bottom surface. The belt includes a pluraity of cutter segments, each comprising a preferably metallic drive block and a metallic carrier block mounted on the top surface of the drive block. The carrier block includes a tooth slot in which a cutting tooth is mounted, such as by silver soldering. The cutting tooth can be a poly-crystalline diamond tooth with a tungsten carbide substrate. The cutting tooth is mounted so that the tooth projects slightly above the top surface of the belt main body. Continuous cables extend along the entire length of the belt and through bores in the plurality of drive locks. The main body is of a resilient material in which the cutter segments and cables are embedded in an injection molding process. The cutter segments are held in position at spaced intervals along the length of the belt by the resilient body. The cutting teeth are arranged in a repeated pattern including two groups of teeth. In one group, the teeth are arranged to converge alternately from each of the opposite sides of the belt toward the center of the belt until a continuous cutting width has been formed. The second group of teeth are similarly arranged, except that the teeth in the second group overlap the teeth of the first group to eliminate streaks along the cutting path.
