Abstract
A sorter having bullpens with double runout lanes and a method for sorting to those bullpens. The sorter comprises a main conveyor conveying articles, such as mail pieces, parcels, or mail trays. Diverters disposed along the main conveyor selectively divert the articles to pairs of side-by-side runout lanes depending on the articles'"'"' destinations. Each pair of runout lanes is flanked on opposite sides across an aisle by a row of destinations, such as carts, baskets, bins, hampers, and pallets. Each article is diverted from the main conveyor onto the runout lane closer to its destination cart. An operator picks up the article and carries it across the aisle to the pre-assigned destination cart.
