Abstract
A method for producing the conveyor assembly is also provided. A plurality of layers of reinforcing material are arranged in overlapping relation. A binding material such as thermoset urethane is deposited on the reinforcing material to bind the reinforcing materials together, thereby forming a composite material. A gripping material is deposited on the composite material, forming a gripping layer. The combined gripping layer and composite material are cured so that the gripping layer permanently bonds to the composite material. The combined gripping layer and composite material are then cut into a plurality of belt links, such that the gripping layer of each belt link is coextensive with the upper surface of the belt link. The belt links are then assembled to produce a link belt having a gripping surface formed from the gripping layers of the individual belt links.
