Abstract (en)

Sheet positioning device comprising conveying means (4,5,6,9) for moving a sheet (8) over a predetermined distance from a starting position, in order to bring the sheet (8) in a required end position, in which the conveying speed of the sheet (8) during the movement is controlled in accordance with a determined required speed course. Upon determining a speed course having a very gradually changing speed, slip between the sheet (8) and the conveying means (4,5,6,9) can be prevented and, accordingly, wear of the conveying means (4,5,6,9) is also reduced to a minimum. By determining the relationship between the required conveying speed course and the actual sheet movement which is the result of the control in accordance with the required conveying speed course and by adapting the required conveying speed course by adjusting the length of a part of the speed course wich has the highest value, in dependence on the determined relationship a sheet (8) can be brought from a starting position to an end position during a very short interval of time with a high positioning accuracy.
