ABSTRACT:
A device conveys and aligns sheets on a feed table of a printing machine having a single-sheet feeder, an aligning section, and a conveying device revolving on shafts for conveying the sheets in a direction across the aligning section to feed rollers for feeding the sheets to an impression cylinder. Bearings are secured to side frames of the feed table so as to be cyclically adjustable in elevation. The shafts are rotatably mounted in the bearings and are cyclically displaceable laterally to the sheet-conveying direction. A guide device is secured in the side frames. A feed plate is carried by the guide device above the feed table and is laterally adjustable with respect to the position thereof on the guide device. The conveying device includes a revolving conveyor device disposed below the feed plate. The feed plate is formed with aligning edges disposed laterally forward of and behind the revolving conveyor device and constitutes a lateral aligning limit. A lower edge of the feed plate extends contact-free over the revolving conveyor device.
