ABSTRACT:
A link belt for use as a conveyor belt or power transmission belt is provided. The belt is formed of a plurality of links forming a series in successive overlapping relation. The upper surface of each belt link includes an electrically conductive layer. Additionally, the lower surface of each belt link may have an electrically conductive layer. The conductive layer or layers provide an electrical path along the belt to impede the build-up of static electricity as the belt is run during use. Further a method for producing the conveyor is provided. A plurality of layers of reinforcing material is arranged in overlapping relation. A binding material such as a thermoset urethane is deposited on the composite material, forming a conductive layer. The combined conductive layer and composite material are cured so that the conductive layer permanently bonds to the composite material. The combined conductive layer and composite material are then cut into a plurality of belt links, such that the conductive layer of each belt link is generally coextensive with the upper surface of the belt link. The belt links are then assembled to produce a link belt having an electrically conductive path.
