Abstract
The document aligning and feeding device comprises couples of rollers formed by a delivery roller (15) and a backup counter-roller (14), wherein each couple of rollers is subjected to a lower load during the aligning step and a higher load during the successive feeding step. The backup counter-roller is formed by two separate, coaxially coupling counter-rollers, one of which (33) has a lower coefficient of friction with the document and is the one operating during the aligning step, whereas the other (31) has a higher coefficient of friction and is operational during the successive feeding step. This allows the document to rotate freely about one of its corners during the aligning step, and to advance without being deflected during the successive feeding step.
