A twin layer packaging machine is disclosed for packing cartons with articles such as beverage cans in two layers, a top layer overlying a bottom layer. The packaging machine has a selector flight defining selector bays, a can flight defining can bays, and a carton flight transporting cartons to be packed, all synchronously movable with each other. A single infeed assembly at the upstream end of the machine directs first groups of cans into selector bays on the selector flight, sweeps them into adjacent can bays, and directs second groups of cans into the same selector bays, all on the same level. The selector flight and the second groups of cans in its selector bays then ramps up to an elevated level, from where the second groups of cans are swept from the selector bays into the adjacent can bays atop the already loaded first groups of cans. The thus staged twin layer cans are then pushed into open cartons on the carton flight, whereupon the cartons are closed and sealed. |
