Abstract: A case packing apparatus for assembling packages or trays of fragile objects, such as eggs or fruit, into case filling stacks, and depositing the stacks into cases. Packages or trays are transported by a conveyor to a transfer plate and transferred thereby onto superposed pairs of opposed retractable support ledges on the opposite inner sides of an adjacent vertically movable stacking cabinet. When a set number of layer arrays has been assembled in the cabinet, the support ledges are retracted sequentially, uppermost first, to cumulatively lower the layer arrays into a solid stack form and lastly to lower the solid stack onto a pair of opposed flexible aprons extending horizontally from the sides of the cabinet under the stack and held taut by bowed flat springs each attached at one end to the corresponding cabinet wall below the upper reach of the extended apron and enveloped by the extended outer reaches of the apron. The aprons are formed of flexible sheet material that is wound in rolls supported on the cabinet for unwinding and winding extension and contraction of the aprons, with unwinding permitting the aprons and springs to move downwardly into a case therebelow and thereby gently lowering the supported stack into the case. The apron and spring are straight and flat when fully extended to permit handling of case filling size stacks with easy retraction of the aprons and springs from between the stacks and case walls.
