Abstract
Abstract A combination punching and binding machine for gang punching a stack of sheets and binding the sheets with a ring-like plastic binding element. The machine has a manually actuated lever which, when operated in one direction, actuates the punches, and when operated in the opposite direction, first moves laterally a comb upon which the binding element is placed and continued movement actuates a plurality of finger elements to uncurl the curled fingers of the binding element for receiving the punched sheets. An alternate embodiment is also included which comprises substituting a first configuration for achieving lateral movement of the comb with a second configuration.
