ABSTRACT:
A wrapping apparatus for wrapping a product in a plastic film includes a conveyor system for moving the product, a wrapping assembly for spirally wrapping a continuous sheet of the film about the product and the conveyor system, and a cutting assembly for forming in the wrapped film a series of perforations defining a line of tearing weakness. The conveyor system includes a pair of spaced apart conveyors which cooperatively move a product through the wrapping assembly. The cutting assembly includes a cutting element which selectively engages the film at a location between the spaced apart conveyors to form the series of perforations.
