a conversion machine configured to receive the sheet material and to form the sheet material into a fill material;
a cutting system configured to selectively cut the fill material either partially or completely to form two pieces of the fill material, wherein:
when the cutting system partially cuts the fill material, a plurality of uncut portions of the fill material remain between the two pieces of the fill material; and
when the cutting system completely cuts the fill material, no uncut portions remain between the two pieces of the fill material;
wherein the cutting system includes a cutter in the form of a V-shaped blade; and
