Abstract
An apparatus for handling horizontally oriented flat circular articles, such as plastic lids, employs a pair of parallel rotating spin bars, one of which is divided or split into a shorter lid entry section and a longer lid discharge section. The shorter lid entry section rotates at the same speed as the other one of the parallel spin bars to stabilize the lids as they sequentially drop off a waterfall conveyor and become vertically on-edge oriented, while the longer discharge section of the split spin bar rotates at a different speed to promote lateral movement of the vertically oriented lids along the spin bars into a stack at the discharge end of the rotating spin bars.
