The invention includes of a system and method of ultrasonically perforating adhesive bandage backings. The invention eliminates the gap between the ultrasonic horn and the pin roll, and provides for a wear resistant release coating on the pin roll. Further, the method and system disclose cooling the ultrasonic horn with a forced air stream, and provide for a pre- or post-nip roll to control the tension of the continuous web of backing. The web of backing is kept under tension with a nip roll, and passes between an ultrasonic horn and an immediately adjacent pin roll for perforation by the ultrasonic horn. The resulting material of the web backing is smoother, and has better hole quality than that seen in the prior art.
