Abstract
A plastic modular conveyor belt of the type having slotted openings in one set of projections for allowing collapse of the inner side of the belt in travel around curves includes a guide roller on the underside of the belt. The guide roller, with a low-friction bearing, smoothly guides the belt so that contact is avoided at the inner side belt edge. In some preferred embodiments the guide roller can also serve as a hold down for the belt around curves, by engaging upwardly against a guide strip. In another embodiment separate hold down tabs are included, so that the roller serves only a guiding function.
