ABSTRACT:
A binding mechanism for use in binding punched and apertured material is disclosed herein. The mechanism includes a comb having teeth or tines for holding a binding element having a plastic-type backbone and curled binding fingers. A slidable hook mechanism is used to engage and uncurl the binding fingers so that the punched and apertured material can be bound thereon. The comb is mounted so as to be transversely slidable from an original position to a second position. A biasing spring is provided for returning the comb from the second position to the original position. This slidable comb cooperates in minimizing damage in the event these binding fingers are inoperatively jammed or wedged between the hook and the comb.
