ABSTRACT:
Articles delivered in side-by-side rows are separated in each row and advanced in pairs to the feeding flights of a wrapping machine conveyor operating at right angles across the ends of the delivery rows, by pairs of accelerating belts that grip the lead pair of articles in the rows between top and bottom belts and advance the pair at a faster rate than the delivery conveyors. Separator bars extending transversely across the paths of the articles are advanced in an orbit around the top accelerating belts and above the bottom accelerating belts by carrier loops located vertically alongside of the accelerator belts. The accelerator belts and the carrier loops are driven intermittently in a cycle synchronized with the feeding flights to advance at higher speed than the article feeding rows during 270.degree. of each cycle and stop during 90.degree. of each cycle with a separator bar in the gap created at the leading end of the delivery rows, to stop a pair of articles at the entrance or "nip" between the accelerating belts.
