Abstract
A modular plastic turn belt has internal modules with link ends of varying shapes, a central body formed for high stiffness, large open area, and light-weight construction. Special edge modules with closer link end spacing and tapered pivot rod slots provide improved edge strength, load distribution, and collapsibility. A bi-directional pitch line drive from both surfaces is provided by a symmetrical drive barrel. Unique hold down arrangements, traction improved constructions, and rod retention arrangements are disclosed.
