Abstract: An apparatus and method by which a single operator, at a single station, can pack pre-counted slugs of flat folded cartons, or trays, in one or more layers, in corrugated cases for discharge to a case taper several times faster than with manual packing by several operators. The "flats" are advanced in a longitudinal path on a secondary apron of a stacker, erect on one edge, pre-counted and divided into slugs, so that the single operator can slide each slug longitudinally past a one-way back stop onto a transfer table. The slug may be turned on its longitudinal axis by the operator for inspection and then compressed longitudinally by a ram against the back stop. The operator has already been presented with a single, flat, tubular case, from a stack of such cases, with the leading flaps folded back, and has manually erected the case and inserted it in a case gripper preferably poised above the table, thereby closing the minor bottom closure flaps.
