Abstract
A binding system for binding a set of media sheets, including a cylinder having an outer diameter and a length, and a retainer fabricated from a flexible material. The retainer has an arc-shaped cross-section having an inner diameter and an associated arc angle thereby providing an opening slot that extends along a length of the retainer. The binding system is adapted to bind the set of media sheets by wrapping the media sheets around the cylinder and inserting the wrapped cylinder into the retainer with the wrapped media sheets extending out of the opening slot in the retainer. The inner diameter of the retainer is less than the sum of the outer diameter of the cylinder and a total thickness of the wrapped media sheets so that the retainer flexes to provide a clamping force to bind the media sheets.
