Abstract
A conveyor belt guide comprises a plurality of guide sections, each including an integral polyurethane elongated rib and base web having a width substantially greater than the rib at its juncture with the web. The base web has a fabric backing molded thereon, upon molding of the rib and base web, at the side of the base web opposite the rib. Each section has tapered ends for cooperating with the ends of adjacent sections to prevent guide stripping. The base web has a greater thickness at its juncture to the rib than at its edges, thereby providing a predetermined primary wear area adjacent the rib and a low coefficient of friction between guide section and supporting slide bed. The sections are laid end-to-end into elongated relieved portions of multiple ply conveyor belts so the base web edges are within the belt plane, but the thicker portion of the belt supports the rib above the belt plane. The section rib is transversely notched toward the base web a distance at least one-half the rib height to provide flexibility.
