ABSTRACT:
A ring mechanism for a loose-leaf binder comprises a thin, elongate plate and at least two ring members supported by the elongate plate. The ring members move between an open position for receiving and removing loose-leaf pages and a closed position for capturing the loose-leaf pages on the ring while permitting movement of the pages along the ring. The elongate plate has a longitudinal end including spaced apart first and second end portions located on one transverse side of the elongate plate. The first and second end portions are bent over to present a longitudinally facing surface which is blunt. A method of manufacturing a ring mechanism for a loose-leaf binder is also disclosed.
