Abstract
A conveyor belt 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.
