ABSTRACT:
A combination punching and binding machine for gang punching a stack of sheets and binding the sheets with a pre-curled plastic comb-binding element. The machine is electrically operated by energizing a reversible motor which, when operated in one mode actuates the punches, and when operated in a second mode, laterally moves a comb upon which the binding element is placed and then actuates a plurality of hook elements to uncurl the curled splines of the binding element for receiving the punched sheets.
