ABSTRACT:
An automatic high-speed wrapping system for wrapping packages in heat sealable thermoplastic film includes a film delivery unit wherein the film is dispensed and wrapped around the packages at a high rate of speed as the packages travel through the system. The packages travel continuously in a straight line through the system and are delivered at the input end of the system by a feed conveyor into a wrapping station where the packages are surrounded by the film, thence to the side sealing mechanism which forms a seal while severing the salvage from the packages, then into an end sealing mechanism where both ends of the packages are sealed and the film web connecting succeeding packages is severed. The film is delivered to the wrapping station in two plies and subsequently inverted for wrapping around the products. The positions of the wrapping station and film delivery units are adjustable to efficiently accommodate a variety of product heights while providing proper film delivery geometry.
