ABSTRACT:
The invention is for a system and method of ultrasonically perforating a continuously moving strip of material in a matrix pattern. The system comprises a knurled rotating drum having sharp, perforating projections over which the strip to be perforated is caused to pass. A sonic horn positioned over the strip forces the strip into perforating contact with the drum, rapidly.
