Title: Package wrapping method and machine

Abstract: The invention provides an improved package wrapping machine which produces a wrapped product having a good seal and a favorable appearance for packages of varying sizes and shapes. More particularly, these improvements are obtained by utilizing a novel film gripper having sections that are separately disengageable to release tension on lateral sections of the film web during the wrapping of smaller than average packages, thereby preventing unwanted stretching of the film so as to promote a good seal for the packaged goods and avoid the formation of unsightly film tails. Also in a preferred embodiment of the present invention, a novel package pusher is utilized to convey the package to be wrapped from a package infeed location to a registration position on the package wrapping elevator.
