An apparatus for handling a plurality of flat, collapsed, folded paper boxes which have been produced on a high speed, folder-gluer, delivered in shingled formation onto the advancing apron of a stacker, counted into slugs of about fifty each and must be packed into cases for shipment. To enable an operator to grasp individual and successive lifts of the flats between her hands and remove them for packing, the apparatus includes a secondary apron traveling at less speed than the stacker apron to raise the shingled flats upstanding on edge, hold down belts to prevent misalignment and a transversely movable segregation rod mounted on a carriage movable horizontally alongside the path of the flats. The carriage has one-way clutch rollers so that the rod will hold back the leading flat but the carriage will roll freely back to the next slug. Speed reduction mechanism may be used to advance the carriage at less speed than the apron to compress the line of flats when edge stacking is desirable or necesary.
