  • Patent number: 4320547
    Abstract: A punch and binding machine binds material into a booklet with a plastic comb-binding in one continuous operation. The machine combines a conventional multiple hole punch with a uniquely designed binder. A conveyor system moves the material first to the punch machine and then to the comb-binder where an auxillary conveyer moves the material into an opened comb-binding so that the extended fingers of the comb-binding may be released to bind the material into a booklet.
