An article merge unit ( 14 ) includes a first conveyor for conveying articles ( 24, 26 ) in a first stream having a first speed, a second conveyor ( 32, 34 ) having a plurality of lateral pushers ( 46 ), and a third conveyor ( 36 ). The first conveyor conveys the articles in the first stream to the second conveyors where the lateral pushers selectively diverting the articles across the second conveyor to the third conveyor. A control controls the conveying speed of the third conveyor and selectively actuates the lateral pushers to push a selected article from the first and second streams to the third conveyor wherein articles conveyed on the third conveyor are conveyed in a take-away stream having no side-by-side articles and the take-away stream has a greater speed than the first speed.
