ABSTRACT:
A sealed envelope, which encloses a rectangular shaped container having an audio or video tape therein to form a package, is automatically removed from the container through cutting a first edge of the envelope during its travel in a first direction and then cutting two substantially parallel edges, perpendicular to the first cut edge, during travel of the container in a second direction perpendicular to the first direction. After the three edges of the envelope have been cut, air pressure is selectively applied towards the cut edges. Then, flexible tubes apply forces to the top and bottom of the cut envelope to partially remove it from the container prior to the container being advanced in the second direction to an area in which a vacuum is applied to remove the cut envelope from the container. The packages are initially stacked in a magazine with each package being advanced from the magazine in the first direction in a predetermined spacing from the prior package. When the container has an audio tape, friction wipers on opposite sides of the container partially remove the cut envelope from the container prior to the air pressure being applied.
