Abstract

A sheet conveying apparatus uses spaced, serially arranged suction chambers to provide suction to overrunning conveying belts. The belts are divergent with respect to each other in the direction of sheet transport to effect a lateral stretching of the conveyed sheets. The conveying belts are slidably supported on an upper surface of the conveying table and may have their speeds individually varied.
