Abstract
A plastic conveyor belt system provides high frictional surface contact between the conveyor work surface and the load carried by the conveyor. This is achieved by modular belt links integrally formed of two diverse plastic materials such as a low friction polypropylene and a high friction elastomer thermoplastic rubber. Typically a belt modular link having a planar load support area disposed in its lower forming mold piece with an upper mold piece removed to expose the planar area. Then a further mold piece is mated with the lower mold piece to integrally join by thermal bonding the two diverse materials producing on the planar link load bearing surface area an elastomer strip with an outer frictionally textured surface for encountering the belt load.
