PCT No. PCT/SE96/01085 Sec. 371 Date Mar. 24, 1998 Sec. 102(e) Date Mar. 24, 1998 PCT Filed Sep. 2, 1996 PCT Pub. No. WO97/09252 PCT Pub. Date Mar. 13, 1997A 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. The upper ply is in abutment with the paper roll and has at least one of elastic properties, hardness and thickness to be able to take-up acceleration and retardation forces acting between the belt and an outer layer of the paper roll without appreciable stretching of material in the upper ply. The upper ply includes an elastic layer covered with an outer, less elastic material. |
