Abstract: An apparatus is provided for decelerating sheets which are to be placed on a stack. The apparatus comprises rotatably driven clamping elements, which are provided with clamping zones that intermittently reach to the feeding plane of the sheet when revolving. The apparatus further includes a mating element which is rotationally disposed on the opposite side of the conveying plane of the sheets such that a sheet can be clamped between the clamping zones and the mating element. The clamping elements are connected to an asymmetrical rotary drive unit while being equipped with ring segment-shaped clamping zones on a section of the circumference thereof. A deflecting device is also provided which deflects the rear edges of the sheet from the feeding plane in a downward direction arranged at a distance from and upstream of the clamping elements in the direction of travel of the sheets.

Abstract: Devices are known for crosscutting webs of paper or cardboard, which include a crosscutting device having two blade drums, which are provided with cross blades. Arranged behind the crosscutting device is a sheet transport device, which includes a braking device having a brake roller. To avoid markings on sheets of delicate paper or cardboard types, the brake roller of the present invention is comprised of a cylindrical base body, on which, at a peripheral distance from one another, radially extending ribs made of a elastic material are mounted, which terminate in a cylindrical enveloping surface, which is coaxial in relation to the base body.
