1. A rolling assembly for packaging web material in a roll, comprising:
a base member having a concave arcuate feed surface defining an upwardly-extending ramp;
a first intermediate member movably coupled to the base member; and
a top member moveably coupled to at least one of the base member or 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 in side view between the feed surface and the pressure surface in the second condition, the second cross dimension being greater than the first cross dimension, and
the iris being configured in the first condition to receive web material along the feed surface and direct the web material upwardly toward the top member to form a roll within the feed space, the iris configured to move toward the second condition as the roll of web material increases in cross dimension against the pressure surface of the top member.
