Abstract

A system holds a roll of film that includes a core and film wound around the core. The system includes a rod having an outer diameter that is smaller than an inner diameter of the core, a proximal wing located on the rod and configured to rotate about the rod, and a distal wing located on the rod and configured to rotate about the rod. Each of the proximal and distal wings includes contact surfaces configured to contact diametrically-opposed locations on a side of an inner surface of the core and non-contact surfaces that span between the contact surfaces of the wing. The non-contact surfaces of the wings do not contact the core if the core has a cylindrical shape. The distal wing is capable of rotating around the rod independently of the proximal wing.
