Abstract: A device for aligning sheets laterally on a feed table of a sheet-processing machine, having a side stop, includes a suction pull nozzle movable transversely to a sheet transport direction and being formed with a plurality of suction openings, the suction openings being distributed so that the number of suction openings arranged in the sheet transport direction becomes greater in a transverse direction towards the side stop.

Abstract: A guide apparatus for guiding sheets to a sheet-processing machine, in particular a printing machine, and a method of operating the guide apparatus are described. The guide apparatus has at least one guide element which is disposed above a feed table and whose distance from the feed table can be set with the aid of a height-adjusting device. The guide apparatus is distinguished by the fact that the height-adjusting device has a first drive and a second drive, which can be actuated independently of each other.
