Abstract:
1. A conveyor belt comprising: a top surface and an opposite bottom surface arranged to advance along a carryway in a direction of belt travel; a pivot rod extending axially perpendicular to the direction of belt travel and parallel to the top and bottom surfaces; a flight having a pivot at one end coupled to the pivot rod and a projection extending outward from the pivot to a distal end, wherein the flight is rotatable about the pivot rod between a retracted position, in which the projection lies along the top surface, and an extended position, in which the projection stands up away from the top surface; and snag-prevention means disposed at the distal end of the flight to prevent the distal end of the projection from catching on discontinuities in the bottoms of conveyed articles while the flight is in the retracted position.
