ABSTRACT:
An apparatus disclosed comprises a manual hole punch which is modified to provide reinforcing rings for punched holes during the punching operation. The modified hole punch includes a tape dispenser mounted at one end of the punch to dispense perforated tape, one side of which has an adhesive applied thereto. The modified hole punch aligns dispensed perforated tape both longitudinally and laterally so that when a piece of paper is inserted within the hole punch, punching units of the hole punch punch holes through the paper and through designated portions of the tape. Simultaneously, staple-shaped cutting members which are mounted on their associated punching elements of the punching units to move therewith, cut through the paper and through portions of the tape between the perforations in the tape to separate the reinforcing rings from the remainder of the tape. The cut tape is collected on a tape collector mounted at the opposite end of the hole punch.
