Abstract (en)
[origin: US5042235A] Goods are packaged by first placing a thermoplastic lower foil atop a pallet with edges of the foil projecting laterally past the pallet and then stacking goods on the pallet atop the foil on the pallet within the edges of the foil. The lower edge of a downwardly open heat-shrinkable foil hood is held as the hood is fitted downward over the stack on the pallet until the lower edge is generally below the stack. This lower edge is then gripped below the stack and the foil hood is shrunk from top to bottom around the stack while continuing to grip the lower edge below the stack. Finally the foil hood is welded to the outer edge of the lower foil. Thus when the grippers are carried on the same vertically displaceable frame as the heater/blowers it is possible for the grippers to release and move upward before the top-to-bottom shrinking of the hood. During such shrinking the clamps will prevent the hood or sack from riding up too much.
