  • Patent number: 12434932
    Abstract: A method for aligning a sheet in a feeder of a sheet-processing machine, where the sheet that is clamped between feed rollers and counterpressure rollers is delivered to a sheet transport device is aligned laterally during this process. First, the sheet is laterally aligned by clamping between feed and counterpressure roller pairs, and a slide to which the feed rollers are mounted, is moved with the clamped sheet transversely to the transport direction in a first direction. Second, the counterpressure rollers are raised from the sheet after the sheet has been gripped by the sheet transport device and before the slide with the feed rollers is moved back to its original position. The return movement of the slide takes place while the sheet, which is no longer clamped, is still present in the region between the feed and counterpressure roller pairs.
