ABSTRACT:
Apparatus for feeding and applying a length of an adhesive tape to a reusable envelope closure. Tape is fed from a supply roll by a draw roll which is in contact with the adhesive surface of the tape to frictionally advance the tape between a stationary knife blade and a rotary knife blade. The tape is cut to a desired length by the cooperating edges of the knife blades and delivered to a vacuum roll which transports the cut length of tape to the envelope and presses it onto the envelope to form a part of the reusable closure. A cooperating convex and concave roller forms the tape into a V prior to it being cut to rigidify it as it is cut. Means are also provided to vary the length of tape which is cut and to stop operation of the apparatus upon sensing the absence of an envelope beneath the apparatus.
