发明名称 Method and device for aligning stacked sheets in a feeder of a sheet-processing machine
摘要 A method and device for aligning stacked or piled sheets in a feeder of a sheet-processing machine, wherein a sheet to be separated is pivotable about a vertical axis extending at least approximately orthogonally to a transport direction of the sheet, as viewed in the transport direction thereof, in order to correct a skewed position of a leading edge thereof relative to at least one front lay. The method further includes determining, relative to the front lay, a skewed position of sheets oncoming at the front lay or resting at the top of the sheet pile, and displacing, transversely or approximately transversely to the transport direction, either the sheet pile, before the sheet is lifted therefrom, or the sheet lifted off the sheet pile, depending upon the determined skewed position, over a displacement distance that is of such length that, after the skewed-position correction, there is a defined spaced distance between a side edge of the sheet and at least one side lay.
