ABSTRACT:
A portable paper hole punch and hole reinforcement tape applicator comprising a housing including operating mechanism for feeding a pressure sensitive tape over a sheet of paper. Punch means and a pressure pad are provided for punching a hole through the tape and paper and applying pressure to seal or bond the tape to the paper. Tape feed means are provided and include means for imparting a transverse curl to the tape so that the latter is stiffened lengthwise to prevent bunching or jamming during the hole punching operation.
The surfaces of all parts of the device contacted by the adhesive side of the tape are coated with "Teflon" or other suitable material, so that the tape will not adhere thereto as it is moved thereover.
