DEVICE AND METHOD FOR ALIGNING A STACK OF SHEETS ARRANGED ONE ABOVE THE OTHER

摘要

The invention relates to a device and a method for aligning at least the front edge of several sheets (04) arranged in a stack, one above the other, whilst maintaining the order of the sheets (04). Said device comprises a stacking table (16), one side of which is provided with a front edge stop for aligning the front edge of the sheets (04). A supporting platform, upon which a stack of sheets (04) can be placed with non-aligned front edges, is arranged upstream of the stacking table (16). The device is provided with a sheet feeder (02), which removes the sheets (04) from the supporting platform by placing them in an overlapping stream with the front edges placed under the preceding sheets. A turning device (06) is provided downstream of the sheet feeder (02), said device turning the overlapping stream in such a way that the front edge area of each sheet (04) is freely accessible. Downstream of the turning device (06), the invention is provided with a conveyer device (17), by means of which the sheets (04) are conveyed, forming a new stack, to the front edge stop of the stacking table (16), where their front edges can be aligned.
