Abstract
A modular plastic conveyor belt with a plurality of modules with interfitting link ends, connected by pivot rods has a rod-retention system with a slidable pivot rod hole blocking member which is inserted from the bottom of the outermost link end of an edge module and is captured in the edge module after insertion while being slidable to blocking and nonblocking positions. The modules are constructed with wide link ends for driving and narrow link ends to create multiple shear planes on one side and constant width link ends on the other side of the module, the constant width link ends being spaced to accommodate the wide and narrow link ends and there being a connecting structure between the link ends for stiffening.
