ABSTRACT:
A device for conveying an imbricated stream of sheets from a sheet pile to a sheet-processing machine includes a conveying table provided with at least one revolvingly drivable, air-permeable conveyor belt. The belt has a top strand with an underside slidable over the conveying table, and a plurality of suction chambers arranged behind one another for subjecting the conveyor belt to negative pressure, so that the conveyed sheets are retained on the conveyor belt until they are transferrable to the sheet-processing machine. It further includes a common negative-pressure supply provided for negative-pressure activation of all of the suction chambers, and at least one throttle via which the suction chambers, respectively, are pneumatically connected to the common negative-pressure supply.
