A delivery device (03) for a sheet-processing machine having at least one delivery station (I) and a conveyor system (21), by means of which substrate sheets (B) that are processed upstream can be received at a transfer point (43), conveyed via a first conveyor section (41) to a first delivery station (I) and there either delivered to a pile (11) to be formed there or conveyed further beyond said pile and conveyed further downstream by the conveyor system (21) via a second conveyor section (42) to a second delivery station (II) comprising a second pile space (46), where they can be delivered by the conveyor system (21) to a second pile (11, 12) to be formed, characterized in that a holding device having one or more holding means (299), which are spaced from one another transversely to the transport direction (T) and which in the holding position are placed in physical contact with the topmost layer of the pile for holding the topmost sheet (B) of the pile (11) down, preventing it from being carried away and/or lifted off when a sheet (B) to be conveyed beyond the pile is being conveyed past, and/or a sheet guiding element (78) which adjoins the first delivery station (I) and at least the upstream end of which can be varied in terms of its vertical position by means of an actuating drive (283, 284) is provided, via which a substrate sheet (B) to be conveyed further downstream beyond the first delivery station (I) by the conveyor system (21) can be guided and transported.
A method for operating a delivery device (03) which comprises a conveyor system (21) by means of which a substrate sheet (B) is conveyed downstream to a delivery station (I;
- II), where it is either delivered by the conveyor system (21) to a pile (11, 12) to be formed there or is conveyed further downstream beyond the pile (11) by the conveyor system (21), via a sheet guiding element (78) adjoining the first delivery station (I) downstream, to a second delivery station (II) comprising a second pile space (46), characterized in that during the transfer of a sheet (B) to be conveyed further, the topmost sheet (B) of the pile (11) is held down from the top by means of an optionally activatable and deactivatable holding device, by holding means (299) which, in the holding position, are placed in physical contact with the topmost layer of the pile, and/or at least the upstream end of the sheet guiding element (78) adjoining the delivery station (I;
- II) downstream in the conveyance path is varied in terms of its vertical position by means of an actuating drive (283, 284).
