A modular roller-top conveyor belt constructed of a series of rows of belt modules having hinge elements at opposite ends of each row. The hinge elements of each row are interleaved with the hinge elements of an adjacent row and interlinked by hinge pins to form an endless conveyor belt. Each of the belt modules includes a body section extending between opposite ends of each row in the direction of belt travel. Cavities formed in at least some of the modules open onto an upper conveying surface of the belt. Rollers residing in the cavities protrude onto the upper conveying surface to engage conveyed articles in rolling, low-friction contact. The rollers may be cylindrical rollers that rotate about axles, spherical balls that rotate in all directions, or caster-like roller assemblies. The rollers may be arranged to rotate about axes in the direction of belt travel for side-off transfer of articles, about axes oblique to the direction of belt travel for side justification, or about axes transverse to the direction of belt travel for low backline pressure.

1. A modular conveyor belt comprising a series of rows of belt modules and hinge pins hingedly interlinking consecutive belt rows end-to-end to form a conveyor belt, each row including at least one module comprising a body section extending from a first end to a second end in the direction of belt travel, a first plurality of hinge elements along the first end, and a second plurality of hinge elements along the second end, the first plurality of hinge elements of a row being interleaved with the second plurality of hinge elements of an adjacent row and pivotally joined by a hinge pin in a hinged connection between consecutive rows of belt modules, wherein the body section of at least some of the modules includes a conveying surface and a driving surface opposite the conveying surface, at least one cavity formed in the body section and opening onto the conveying surface, and a roller rotatably disposed in the cavity to rotate about an axis oblique to the direction of belt travel with a salient portion of each roller protruding above the conveying surface to engage conveyed articles in rolling contact and wherein a salient portion of each roller protrudes through the driving surface to engage a roller bearing surface to rotate the roller as the belt is driven.
