  • Patent number: 6092645
    Abstract: A conveyor belt intended for use as an endless conveyor path in a materials transporting system includes an upper ply, a load-absorbing intermediate ply, and a lower ply that provides wear protection against one or more belt supporting devices. The intermediate ply includes a load-absorbing fabric. The upper ply provides protection against wear by transported goods. The upper ply has at least one of sufficient softness and formfactor to take up shear forces acting in the belt, the shear forces being caused by a load exerted on the belt by the goods transported thereby upon retardation and acceleration of the belt and also by coaction of the belt with the belt supporting devices. The conveyor belt is an endless conveyor path for one or more paper rolls. The conveyor belt is positioned flush with a surrounding floor surface.
