Abstract

An improved machine is disclosed for stacking a plurality of flat objects (10). The improved machine for stacking is suitable for use with a packaging machine such as a shrink wrap packaging machine (4) for packaging the plurality of flat objects (10) with a heat shrinkable film (25). An input conveyor (44) individually conveys each of the plurality of flat objects (10) to the stacker (50).
The stacker (50) forms a vertical stack of the flat objects (10) from the plurality of flat objects (10). The stacker (50) may be used in conjunction with a wrapper (90) to form the heat shrinkable film (25) into a film tube (30) with the vertical stack of flat objects (10) disposed therein. An input oven transport (110) transfers the vertical stack of flat objects (10) to a heat shrink oven (112) to form a heat shrink package (20) thereby. The invention is also incorporated into the shrink wrap package (20) having an electrostatic seal (32) enabling an operator to twist the heat shrink package (20) to fracture the electrostatic seal (32) for removing the stack of flat objects (10) therefrom.
