ABSTRACT:
An apparatus and method for installing binder elements onto a stack of pre-punched paper including a platform for holding the paper, reciprocating guide fingers for inserting through the pre-punched holes to engage free ends of curled fingers of the binder element whereas the spine part of the binder element is restrained by a holder which moves laterally to spread apart the curled fingers. The spread apart curled fingers then are flattened and driven upwardly through the holes as the guide fingers retreat upwardly and thereafter separate from the curled fingers to complete the binding of the pages.
