Claim 18:
19. A method for packaging web material in a roll, the method comprising:
providing a rolling assembly configured to receive a stream of web material, the rolling assembly comprising:
a base member having a concave arcuate feed surface defining an upwardly-extending ramp;
a first intermediate member moveably coupled to the base member; and
a top member moveably coupled to at least one of the base member and the first intermediate member, the top member having a concave arcuate pressure surface facing the feed surface of the base member;
wherein the base member, the first intermediate member and the top member collectively form an iris with a feed space defined between the feed surface and the pressure surface, the iris being moveable between a first condition and a second condition, the feed space having a first cross dimension in side view between the feed surface and the pressure surface in the first condition and a second cross dimension between the feed surface and the pressure surface in the second condition, the second cross dimension being greater than the first cross dimension; and

delivering a stream of web material including a plurality of plastic bags in a shingled arrangement to the assembly, the iris receiving the web material along the feed surface and directing the web material upwardly toward the top member to form a roll within the feed space, the iris moving toward the second condition as the roll of web material increases in cross dimension against the pressure surface of the top member.
