Abstract
The cutting mechanism has a stationary anvil and a movable knife that is swung across the path of travel of the taut, moving wrapper to deflect the wrapper into engagement with the anvil and accomplish severance. A tapered nose on the anvil fits into a slot along the length of the knife as the two components come together whereby the wrapper is stuffed by the nose of the anvil into the slot in a distorted condition, conforming to the shape of the nose and bending over a sharp edge along the slot. As the wrapper becomes gripped within the slot and bent over the cutting edge, it is severed cleanly from the roll and the severed length of the wrapper is delivered to the bale for completion of the wrapping cycle. The knife is in the nature of a tubular member with a slot in its peripheral wall so that the arcuate outer surface of the wall slidingly engages and keeps the wrapper out of contact with the sharp edge until the anvil enters the slot, thereby preventing premature snagging and severance of the wrapper by the sharp edge.
