Abstract
An occlusion system is provided for retaining pivot rods of modular link belts in residence in journalled positions within the designated sets of aligned link end apertures with particular advantages in reducing belt wear and maintaining belt lengths more stably in the presence of load and slack conditions. Thus the pivot rods are confined in journalled positions in pivot apertures in the link modular link ends by way of a belt edge occlusion member which is a stiff integral modular member that covers a significant portion of the journalling aperture area. The occlusion member has a notch shaped as a cylindrical segment for mating with a headless flexible pivot rod to guide it into a journalled position with a set of apertures as it is bent to pass the occlusion member in entering or leaving a journalled position within a set of apertures.
