Abstract
A method of aligning sheets prior to transferring them to a sheet-processing machine includes feeding a respective sheet, by a first sheet edge thereof, against a stop; gripping the sheet by at least one sheet holder, and displacing the sheet holder at least approximately transversely to the stop in a direction towards a first control region; and onwardly moving the sheet holder, while the sheet is held thereby, over a given first distance, after a second sheet edge has reached the first control region; and a device for performing the method.

A method of aligning sheets prior to transferring them to a sheet-processing machine, which comprises feeding a respective sheet, by a first sheet edge thereof, against a stop;
- gripping the sheet by at least one sheet holder, and displacing the sheet holder at least approximately transversely to the stop in a direction towards a first control region;
- and onwardly moving the sheet holder, while the sheet is held thereby, over a given first distance, after a second sheet edge has reached the first control region.
A device for aligning sheets prior to transferring them to a sheet-processing machine, having at least one actuating system including at least one sheet entrainer, comprising an actuating drive for displacing the entrainer, said actuating drive being a piezoelectric micro-thrust drive.
