摘要： A system for perforating record media by the use of ''''stationary'''' perforating equipment, i.e., in which the punches do not move in the direction of movement of the record media. The record media is transported through the perforating equipment by frictionally engaging the surfaces of the record media with a plurality of continuously driven rollers. The continuous frictional drive applied to the record media is maintained during the perforating of the record media to obtain high throughput rates. The frictional drive rollers are skewed so as to urge the media against an inturned flange on one side of the media supporting surface. A photoelectric sensor senses the position of the record media for actuating the punches only when media is present at the perforating station.
