ABSTRACT:
A baggage protection device wherein the device consists of a base carriage onto which is mounted a turntable with a securing device. Also mounted on the base carriage is a roll of stretch-wrap plastic film, along with feeder posts and a vertical frame. An alternative embodiment of the baggage protection device consists of a base carriage unit having a rear section and a front section which may be extended outwards from the rear section to accommodate larger baggage to be wrapped thereon. A turntable is mounted on the front section of the base carriage unit, the turntable having a pair of hydraulic rams which act to urge together a pair of grip tongs movably mounted on the upper surface of the turntable. Mounted atop the rear section is a roll of stretch-wrap plastic film. As the plastic film is drawn from the roll, it passes around an idler roller and around a tensioning roller, the tensioning roller and idler roller being in contact with one another. The stretch-wrap plastic film then is placed on the baggage to be wrapped, tension being provided by the tensioning roller and idler roller combination. For controlling the overall operation of the unit, a programmable controller may be provided. A piece of baggage is protected by securing it on the turntable and feeding one end of the plastic film between the feeder posts, or around the idler roller and tensioning roller, and attaching the film to the baggage. The turntable is then rotated and the baggage wrapped in stretch-wrap plastic film. The film is then divisioned and the free end of the plastic film is secured to the wrapped piece of baggage to complete the process.
