ABSTRACT:
A fully automatic stationary wrapping mechanism is utilized in conjunction with an upstream palletizing device and a downstream distribution system. An inbound zone accepts palletized materials and selectively passes them along to a wrap zone. An outbound zone provides a direct link with the wrapping device in any downstream distribution conveyor system. The apparatus provides a relatively short, straight pathway from the point of construction of the loaded pallet through the wrapping station to the outbound conveyor. An improved film gripping device is provided as an elongated arm, extendable from a home position outside the wrapping area to within the wrap zone in order to grip the film, and such that the specific location of the free end of film is not particularly critical. Following the wrapping operation, a length of fresh, unstretched film is extended, and an improved cutting device utilizes a heating element enclosed within a housing having an opening adjacent the heating element to sever the film at this point. The film is drawn across the housing and is severed by localized melting adjacent the location of the opening in the housing, providing a clean, predictable, unstretched termination to the film while preventing direct contact of the melting film material with the heating element itself.
