ABSTRACT:
An improved machine is disclosed for stacking a plurality of flat objects. The improved machine for stacking is suitable for use with a packaging machine such as a shrink wrap packaging machine for packaging the plurality of flat objects with a heat shrinkable film. An input conveyor individually conveys each of the plurality of flat objects to the stacker. The stacker forms a vertical stack of the flat objects from the plurality of flat objects. The stacker may be used in conjunction with a wrapper to form the heat shrinkable film into a film tube with the vertical stack of flat objects disposed therein. An input oven transport transfers the vertical stack of flat objects to a heat shrink oven to form a heat shrink package thereby. The invention is also incorporated into a shrink wrap package having an electrostatic seal enabling an operator to twist the heat shrink package to fracture the electrostatic seal for removing the stack of flat objects therefrom.
