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.
Claims4
A device for aligning a sheet having a first sheet edge and a second sheet edge prior to transferring the sheet to a sheet-processing machine, the device comprising:
- at least one displaceable sheet entrainer with an actuating drive, said actuating drive being a piezoelectric micro-thrust drive;
- at least one stop for aligning the first sheet edge;
- and
- a control region for capturing the second sheet edge.
