Claim:
1. A method for automated opening polyfilm wrapping on a package, comprising: providing a plurality of packages moving on a conveyer that are each wrapped at least in part in a polyfilm wrapping, wherein the contents of each package are one of magazines, mailpieces, paper, cardboard, bottles, glass, or cans; providing an automated machine tool having a rubbing surface, the machine tool comprising a hardware controller preprogrammed with parameters to allow controlled automatic opening of the package, wherein the rubbing surface is a friction belt configured to be rotated by a motor, wherein the friction belt is mounted on a drive roller driven by the motor and an idler roller, the friction belt being supported by a frame; lowering the frame by an actuator coupled to the frame, thereby lowering an end of the friction belt, and a section of the end of the friction belt comes in contact with a surface of the polyfilm wrapping of each package on the conveyer; applying the rubbing surface to the polyfilm wrapping of each package on the conveyer; controlling movement, using the hardware controller, of the rubbing surface and application of the rubbing surface to the polyfilm wrapping of each package, the hardware controller being configured to control the motor and the actuator; and creating an opening in the polyfilm wrapping of each package caused substantially by friction heat via the rubbing surface rotating and moving relative to the polyfilm wrapping of each package, without damaging the contents of each package, the parameters preprogrammed in the hardware controller including a dwell time required to generate the friction heat to produce the opening of each package.
