ABSTRACT:
A series of rows of belt modules wherein a first one of the rows may have a plurality of hinge elements along an end of the first row. A second one of the rows may have a plurality of hinge elements along an end of the second row. The plurality of hinge elements of the first row may be interleaved with the plurality of hinge elements of the second row. A pivot rod may extend through the plurality of hinge elements of both the first row and the second row so as to pivotally join the first row to the second row. A sphere may be supported from a first module of the first row and supported from a second module of the first row, so that the sphere resides between the first module and the second module and so that the sphere extends above the modules in order to allow an object, which is to be conveyed by the conveyor belt, to be supported on the sphere. The modules may be moved in a belt travel direction in order to convey the object from a first location to a second location.
