Apparatus for collecting, counting, stacking, turning over and arranging bags or sacks produced in a high production bag manufacturing machine for assembling and wrapping in desired bundles of uniform dimension for shipment or storage. The apparatus is synchronized with the bag machine to automatically accept the output therefrom for collecting in discrete stacks of a given quantity which are then overturned and fed by a conveyor into a wrapping apparatus with the bottoms of the bags of adjacent stacks positioned at opposite ends for assembling and wrapping in bundles of a uniform thickness to accommodate storage and shipment of the wrapped bundles.
