Abstract
A bagging conveyor quickly positions two-dimensional arrayed layers of objects inside a sealed, flexible bag prior to the layers of objects being delivered by the bagging conveyor to a palletizer. The bagging conveyor receives continuous films of packaging material from below and above the conveying surface of the bagging conveyor and positions the films of packaging material below and above the layer of objects being conveyed by the conveyor. The bagging conveyor then forms seams along the laterally opposite side edges of the packing material films at the sides of the conveyed layer of objects and forms seams laterally across the upper and lower films of packaging material in front of and behind the conveyed layer of objects, thereby quickly enclosing the conveyed layer of objects in a sealed bag as they are conveyed through the bagging conveyor.
