ABSTRACT:
Apparatus for tightly wrapping a package such as disposed on a pallet in a thin film such as for shipping or storage includes a rotating deck adapted to receive the pallet and package to be wrapped. The deck is directly coupled to and supported by a gear box driven by an electric motor. The apparatus further includes a film wrap supply in the form of a roll which lets out the film for wrapping around the package as the deck and package rotate. A manually adjustable tensioner allows for adjusting the stretch of the wrapping film on the package, while the film wrap supply may be adjusted vertically to permit wrapping the package over its entire vertical dimension regardless of the width of the roll of film wrap. A foot control allows an operator of the apparatus to rotate the deck and the package being wrapped while vertically moving the film wrap supply roll-to fully enclose the package within the wrapping film.
