Abstract
A conveying belt having a belt body with oppositely facing inner and outer surfaces and a width between laterally spaced sides. The belt body has a first layer, with the first layer being an elastomer with a first plurality of discrete fibers therein having lengths substantially less than the width of the body. The lengths of the fibers in a second plurality of fibers in the first plurality of fibers are randomly oriented and reside substantially in a single plane. The invention is also directed to a method of making the conveying belt.
