ABSTRACT:
A conveyor having rollers supported above the conveying surface of a belt to prevent conveyed articles from being stranded atop flights or other positioning elements. The rollers may be passive or driven actively either directly by rolling contact with a carryway or indirectly through a transmission linked to accelerating rollers in direct contact with a supporting carryway. Accelerating rollers extend through the belt past the conveying surface to support conveyed articles and past an opposite surface of the belt into rolling contact with the carryway. The accelerating rollers may be axle-mounted, in-line or oblique, or freely rotatable roller balls. As the belt advances, the accelerating rollers propel conveyed articles forward over any supported roller the article is leaning on into a registration position against a flight, frictional area, or other registration element.
