Abstract
A method of controlling or regulating the vertical position of piled or stacked sheets, which includes determining at the leading edge and at the trailing edge, respectively, of the sheet resting on the top of the sheet pile, the vertical position of the sheet: and, depending upon the vertical position of the leading edge and the trailing edge, respectively, moving in the vertical direction at least one lifting element associated with the sheet trailing edge. The method further comprises, displacing the sheet pile and the lifting element, respectively, a given distance in the vertical direction, when a large discrepancy is found between the vertical position at the leading edge and a nominal value.
