Abstract
Sheets of wrapping film are drawn into a wrapping machine from a continuous film source to accommodate large girth packages. Predetermined lengths of film corresponding to the entering lengths of the packages to be wrapped are initially drawn into the machine, with additional film being drawn in accordance with the girth dimensions of the packages. In a first embodiment, the additional film is drawn from the source by fully elevating packages into the film with the stress thus produced pulling the additional film required. In a second embodiment, a secondary package pusher is connected to a rear underfolder such that as the film is folded beneath a package, any portion of the package exceeding a given length is pushed from the wrapping station beyond a film edge-engaging position to draw additional film approximately equal in length to the extended portion of the package. In a third embodiment, the film is drawn from the source by means of a gripper which is pivoted to draw additional film in accordance with the girth of a package as determined by the entering length of the package.
