Abstract

The invention relates to an apparatus having means for delivering, depositing, and aligning individual sheets (S) in a collecting tray (7) to form at least one sheet stack (8) from sheets collected one on top of another, the collecting tray of which has a depositing surface (70) with at least one front delimiter (71) against which the sheets are aligned, and having a holddown element (3) resting on the sheet stack, wherein the alignment means (1) for aligning a topmost delivered sheet (S) are drivable by a drive unit (6) and the alignment means are movable together with the holddown element relative to the stack in the stacking direction. To create an apparatus which prevents high wear on the alignment rollers and high loading of the topmost sheet of a sheet stack while at the same time reliably aligning the sheets delivered onto the stack and, in addition, securely holding the sheet stack in the collecting tray, a radial cam (2) is provided for the alignment means (1), which cam is supported on the holddown element (3) and by which the alignment means (1) can on the one hand be brought out of engagement with the topmost sheet of the stack during delivery of a sheet (S) to the stac…
