Abstract
Sheet feeder for a sheet-processing machine having a device for automatically aligning a lateral position of a stack of sheets from which respective sheets to be individually separated are detectable by a conveyor device for transporting the sheets in a given transport direction and feedable to the sheet-processing machine, includes a stack table for carrying the stack of sheets, the stack table being movable transversely to the given transport direction of the sheets, servomotor means for moving the stack table transversely to the given transport direction in response to respective control signals from an actual sheet-position detection device disposed immediately downstream of the sheet stack as viewed in the given transport direction, the detection device having means for detecting the lateral position of the respective sheet just separated from the stack and already fed to the conveyor device.
