1. A belt module, comprising:a base extending from a first end to a second end and transversely across its width from a first side to a second side, the base including an upper deck; a first set of hinge elements extending from the first end and spaced apart along the width of the module, each of the first set of hinge elements forming a transverse aperture therethrough; a second set of hinge elements extending from the second end and spaced apart along the width of the module, each of the second set of hinge elements forming a transverse aperture therethrough; a plurality of supports upstanding from the upper deck and spaced apart across the width of the module to define a space between consecutive supports, wherein consecutive supports form aligned transverse openings and have transverse thickness dimensions; an axle supported by the aligned transverse openings of the consecutive supports; and a plurality of rollers, each including a central axial bore to accommodate the axle and each disposed in a respective one of the spaces between consecutive supports, wherein each space is slightly greater along the width of the module than the axial length of the roller disposed in the space and much greater than the transverse thickness dimensions of the supports to provide the module with individually supported rollers closely positioned across the width of the module.
