Abstract
A paper stock adapted to be employed in transport systems utilizing projecting pin-type sprocket drives includes at least one row of a plurality of spaced-apart and aligned pin-engageable drive apertures extending the length thereof, each of which drive apertures is formed by a partially open circular die-cut line having a gap between its ends of approximately 0.010 inches to 0.040 inches, the gap being oriented at the leading edge of the resulting aperture, thereby forming a strengthening hinge-like connection between the paper stock and the aperture blank when such blank is subsequently displaced, such as by engagement with a projecting pin on a drive sprocket mechanism of a transport system used to move paper stock through a machine.
