ABSTRACT:
Pull tabs are applied to the two ends of the sealing courses of pressure sensitive tape applied to rectangular shipping cartons. A masking material is applied to the pressure sensitive tape during the taping operation so that the masking material will be adhered to a part of the sealing tape as a pull tab means which is applied to the rear wall of the carton being sealed and a part will be left on the tape stock to provide a pull tab means on the front wall of the carton to be next taped from the tape stock. An apparatus for forming these pull tab means also is provided.
