Rubber Covers are used in conveyor belt constructions in order to protect the base conveyor belt carcass and, if possible, to extend its service life. In addition, covers do provide the finished belt with a wide variety of desirable properties, including the following:
Rubber Cover type, quality and thickness are matched to the service life of the belt involved. A specific cover formulation used in an individual belt construction is determined by the material to be carried and the environment in which the belt will operate.
Historic belt constructions were highly susceptible to moisture and chemical attack because of their cotton carcass components. Accordingly, it was common to extend the belt covers over the edges of the belt in what is known as the molded edge construction. This type of manufacturing can be expensive because of the additional labor and machine time involved.
Modern day belt constructions, with their high adhesion levels and synthetic carcasses, are considerably less susceptible to moisture and chemical attack and do not require edge protection. They make possible the slit-edge belt distribution programs currently used in the belting industry.
