Abstract:
A method for proper alignment of sheets comprising the steps of:feeding a sheet toward a front guide of an aligning stop; moving the sheet toward a side guide of the aligning stop using a movable carrier, the sheet having a maximum sheet speed; generating a signal when a side edge of the sheet passes a location, the location being a predetermined distance from the side guide of the aligning stop; performing a preset movement with the carrier in response to the signal, the preset movement being towards the side guide of the aligning stop and being identical for each sheet to be fed, and the preset movement causing the sheet to proceed with a speed greater than zero and substantially less than the maximum sheet speed as the sheet reaches the side guide of the aligning stop; and transferring the sheet to a sheet-processing machine; wherein a force of friction between the carrier and the sheet is selected such that the sheet will slip in relation to the carrier if the sheet strikes the aligning stop during the preset movement; and wherein the preset movement is over a predefined distance more than the distance between the location and the side guide.
