Abstract: Plastic conveyor belts made up of modules interconnected by transverse rods and capable of straight or radius travel are adjusted as to minimum radius the belt can traverse by restricting collapsibility at the inner edge of the belt. This can be accomplished using shims in the slotted apertures of link ends, preventing full rod travel in those apertures, at each row or at alternating or selected rows of the belt; or shims otherwise placed in the belt to prevent full collapse; or by using different modules in certain rows, with less collapsibility; or by substituting different edge modules in belts of multiple modules per row. In this way, a basic radius conveyor belt can be defined, with a relatively tight minimum radius, and then can be modified so as to be custom-fitted to spiral conveyor or other belt systems having specific curve radii which are larger than the radius of the basic belt.

Abstract: A chain link conveyor belt carries lateral slats extending from the chain links, upon which are formed integral ribbed finger load carrying platform structure that interdigitates and overlaps their ribbed fingers with leading and trailing chain links in a conveyor belt.

The chain links are Y-shaped with elongated pivot rod slots in the leg to permit flexibility for laterally pivoting the belt around curved paths. Specially shaped structure on the slats near the belt edges supports long finger tip ribs of adjacent slats, thereby to strengthen the edge portions of the belt. The outermost fingers are reinforced to slide on guide rails. The trailing ribbed fingers diverge inwardly from the belt edges to avoid interference and fracture.

Abstract: Modular conveyor belt links have edge structure for occluding exit of pivot rods from the edge of the belt during operation of conveyor belts formed from pivotably connected end-to-end links. The links feature belt edge structure with an outer pivot rod entry aperture offset from the axis of aligned link end pivot rod holes in one set of link ends thereby forming a pivot joint axis. When the pivot rod is forced from the belt edge into the offset aperture and headed toward the pivot joint the plastic link is elastically deformed enough to permit entry of the rod. For example, an occlusion barrier wall disposed near the belt edge retains the rod in the pivot joint. A matrixing nest for the end of the pivot rod resident in its axial joint site is formed in the link material. From this nest the rod can be removed only by forced distortion of a rod end by a force greater than those forces encountered in the course of normal belt operation.
