    摘要： A conveyor belt (10) having a width and a length, and a longitudinal centerline, also has a first longitudinal edge, and an opposing second longitudinal edge and a load bearing region. The load bearing region is located evenly about the belt longitudinal centerline, throughout the length of the belt. The conveyor belt also has a first flexibility region and a second flexibility region, wherein the first flexibility region is located between the first longitudinal edge and the load bearing region, and the second flexibility region is located between the second longitudinal edge and the load bearing region. The conveyor belt further comprises at least one fabric layer, having a width corresponding to the conveyor belt width, and having a length corresponding to the conveyor belt length, wherein the fabric layer has a density which varies over the fabric layer width; and wherein the fabric layer density is higher in the first and second longitudinal edges and the load bearing region than the fabric layer density in the first and second flexibility region.

    摘要： The present invention provides a conveyor belt rip detection system with belts having rip detection inserts that can be more easily integrated into conveyor belts at low cost. These rip detection inserts do not adversely affect the durability of the conveyor belt and can be easily replaced in the event of belt damage. This rip detection system also provides a highly reliable early image of belt damage that can facilitate quick repair before extensive belt damage occurs. The present invention more specifically discloses a conveyor belt comprising (1) an elastomeric body having a load carrying surface and a parallel pulley engaging surface; (2) a reinforcement ply disposed within the elastomeric body; and (3) a multitude of rip detection inserts, wherein the rip detection inserts are spaced along the longitudinal length of the conveyor belt, wherein the rip detection inserts contain a multitude of rip detection wires that are comprised of a magnetically permeable material, wherein the rip detection wires are aligned in the rip detection inserts at a bias angle of 15° to 75° from being perpendicular to the longitudinal direction of the belt, and wherein the rip detection wires are spaced incrementally across the width of the belt.
