Abstract
An apparatus and cartridge for use in binding prepunched sheets into a booklet using curled-finger ring-type edge binders. The binders include an opening tool which is drawn through the binder for spreading curled binder finger from the binder spine to form a document receiving gap. Binder/tool combinations are carried in the cartridge which includes a binding position or slot. The cartridge is to be positioned in an apparatus having a recessed base for receiving the cartridge and a cover which includes a paper receiving slot. The base defines a slot for alignment with the cartridge binding position slot. In the opened position, the terminus of the cover slot is aligned with the base slot. When the cartridge is in position and the cover opened, a booklet can be formed at the binding position by a binder being opened, apertured paper deposited in the cover slot and binder, and removal of the opening tool to permit the binder to close on the apertured paper. In an alternative embodiment, various binder guiding elements, such as a well, upstanding ribs, and a ledge are defined by the base itself so as to eliminate the use of the cartridge.
