Abstract
A monolithic conveyor belt structure comprising an elongate, substantially planar base belt having a pair of integrally formed, flexible, fabric reinforced, longitudinal sidewalls protruding from its top face. The integral construction prevents delamination of the sidewalls from the base belt, and the fabric reinforcement in the sidewalls strengthens the sidewalls against deterioration due to repeated flexure of the belt, and due to contact with pulleys, turn disks, sliding surfaces, etc. The belt may include cleats between the sidewalls, such as transverse paddles or upstanding nubs, to assist in conveying material on very steep inclines.
