Abstract
The present invention is directed toward an apparatus for making a package from a load using a single web of stretchable film material to form the overwrap. The apparatus comprises a frame, a support assembly secured to and extending from the frame, and a film dispenser mechanism rotatably mounted to the support assembly. The film dispenser mechanism comprises an arm member, a counterbalance weight on one end of the arm member, and a film stretching mechanism mounted on the other end of the arm member adjacent to a roll of stretchable film material which is also mounted on the arm member. The film stretching mechanism is constructed with two rollers closely spaced apart and mechanically connected, with the upstream roller being driven by a drive member mounted to it or its shaft. The drive member engages the downstream roller to drive the upstream roller slower than the downstream roller causing film material which is being pulled from the roll of film material to be wrapped around a load carried on the support assembly so that the load is wrapped with a plurality of layers of prestretched tensioned film material to form a wrapped tensioned package.
