Patent ID: 8650996

Claim:
A method of creating perforations in a wrapping film, the method including the steps of: a) providing a free-wheeling support bar including a plurality of needle points disposed around the perimeter thereof in a predetermined pattern; b) placing the free-wheeling support bar in contact with a driven roller used to unroll wrapping film from a stock roll, the driven roller formed of a pliable material, with the free-wheeling support bar placed in contact with the driven roller such that as the driven roller is powered to rotate, the free-wheeling support bar rotates in a counter direction; c) threading the wrapping film between the driven roller and the free-wheeling support bar so that the wrapping film is in contact with both the driven roller and the free-wheeling support bar; d) activating the driven roller to rotate and unroll the wrapping film from the stock roll, the activation of the driven roller causing the free-wheeling support bar to counter-rotate; and present needle points against the pliable driven roller in a continuous manner; and e) piercing the wrapping film passing between the driven roller and the free-wheeling support bar with the counter-rotating needle points to create perforations in the wrapping film.
