ABSTRACT:
A collecting station (1) has a first (3) and a second lateral side guide (4) which are movable transversely to the direction of transport (A). The first side guide (3) has a rigid alignment surface (3a) with a convex, arcuate surface and, for the alignment of a deposited sheet, is moved at a first, high speed to an intermediate position and from there at a second, lower speed to the alignment end position. The second side guide (4) is provided with flexible bristles (5) which compensate for sheet tolerances and which are inclined downwards at an angle of 45.degree.. When the first side guide (3) comes to a standstill, the second side guide (4) is moved at a high speed to the alignment end position, then at a high speed back to an intermediate position in which contact with the sheets is no longer established, and thereafter at a lower speed back again to the alignment end position. For the return of the side guides (3 or 4), firstly the second side guide (4) and then the first side guide (3) are moved.
