There is disclosed herein an apparatus and method for binding prepunched and apertured materials together with a curled-finger ring-type edge binder using an elongated tool. The tool includes leading, intermediate and trailing sections. The leading section is longer than the binder, but not as wide. The intermediate section which uncurls the fingers taperingly joins the leading and trailing sections. The trailing section is longer and wider than the binder, holds the fingers open, aligns the prepunched paper relative to the fingers and can form an upwardly-facing paper receiving gap. The back end of the trailing section is transverse to the longitudinal axis of the tool for releasing the fingers so as to allow each finger to release its potential energy, extent or snap through the aperture and thus bind the paper together.
A tool for use in opening a edge-type curled-finger ring-binder having an elongated spine and a plurality of spaced transversely extending binding fingers, each of said fingers having an end integral with one side of the spine and being curled so that the free end thereof can resiliently engage the other edge of the spine, wherein the tool comprises:
In combination, a ring binder and a tool for opening said ring binder comprising:
