Abstract
A modular conveyor belt having extended raised ribs that overlap to prevent the top conveying surface of the belt from opening up as the belt articulates forward around a sprocket at a hinge joint. Protrusions extend from the raised ribs past the ends of the belt modules. When rows of belt modules are connected together at hinge joints, the interleaved protrusions overlap laterally over a range of articulation angles. The modules may include cavities for roller assemblies, such as engaged stacked rollers in which a bottom roller is allowed to float vertically to maintain good contact with the top roller as they wear.
