ABSTRACT:
A binding system for loose-leaf sheets of paper that securely retains the paper and provides facile removal and addition of paper bound by the system is provided. The system provides a variable width binding, for addition and removal of papers, and a flexible spine. A plurality of resilient connecting members extend arcuately between first and second backing members, when the system is in an open position. The connecting members extend through openings in an adjustment assembly coupled to the second backing member. The adjustment assembly is provided for simultaneously increasing and decreasing the length of the connecting members, and for maintaining the connecting members at different desired lengths for binding paper with the system or removing paper from the system. Paper having a plurality of slots is positioned on a cover, with a connecting member extending through each slot. The adjustment assembly is actuated for either reducing the length of the connecting members, to draw the backing members together and bind the papers therebetween, or for increasing the length of the connecting members, for adding or removing papers bound by the binding system.
