Abstract
A conveyor roller tube (1) including a plurality of co-extruded polymer layers (2, 3). The tube (1) includes an inner layer (2) and an outer layer (3), and an optional intermediate layer. The inner layer (2) is formed of a first polymer material. The outer layer (3) is formed of a second polymer material. The outer layer is formed to have high wear properties and is also formed to be of a different color to the adjacent layer (2) thereto so that a visual indication of the wear of the roller tube (1) is provided.
Claims15
A conveyor roller tube for a conveyor system, the conveyor roller tube comprising:
- an inner layer formed of a first polymer material;
- and,
- an outer layer formed of a second polymer material including a second layer additive to thereby provide high wear-resistant properties;
- wherein said conveyor roller tube is formed by a coextrusion process in which each of said first and second polymer materials are of a different color, and are co-extruded from separate hoppers using a single extruder die, to thereby form said roller tube having differently colored polymer layers, and
- wherein, in use when rotating in a conveyor system, the color difference between the inner and outer layers of said roller tube provides a visual indication of the wear of said roller tube.
