ABSTRACT:
A reinforced conveyor belt especially suited to transport sharp objects such as glass and scrap metal. The belt has a top and bottom layer of flexible, abrasion-resistant material, such as rubber. There is a middle layer of woven, multi-layered fabric, preferably made of cotton threads with reinforcing rods interwoven therein. The reinforcement rods run transversely and occupy sites in the intermediate layers of the fabric normally occupied by weft threads. Interweaving the layers of fabric and inserting the rod into one of the intermediate fabric layer provides the belt with tensile strength, puncture resistance, and a barrier against longitudinal tearing. Finally, the bottom surface of the belt is textured to provide additional durability and traction.
