Abstract

A device for producing a scaled stream with a controllable scaled-stream thickness has a sheet guiding device for receiving therein a stack of sheets, a first transport means, which has a selectively operable or controllable drive, which engages only the lower surface of the stack of sheets and which is arranged relative to the stack of sheets in such a way that the stack of sheets rests thereon with at least a first part of its weight, a second transport means, which is arranged behind the first transport means when seen in the direction of the stream of sheets, which is arranged relative to the stack of sheets in such a way that, when the second transport means is operated without operating the first transport means, it will transport only sheets which have already been drawn out of the stack of sheets by the first transport means, and which is also arranged relative to the stack of sheets in such a way that the stack of sheets rests thereon only with a second part of its weight, the second part of its weight being small in comparison with the first part; a scaled-stream thickness detection device for detecting the scaled-stream thickness, which operates or controls the drive of …
