摘要： An apparatus is provided for decelerating sheets, especially paper or cardboard sheets, which are to be placed on a stack. The apparatus comprises rotatably driven clamping elements, which are disposed across the width of the apparatus on at least one side of the conveying plane of the sheets and are provided with clamping zones that intermittently reach all the way to the feeding plane of the sheet when revolving. The apparatus further comprises 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. Furthermore, a deflecting device which deflects the rear edges of the sheet from the feeding plane in a downward direction is arranged at a distance from and upstream of the clamping elements in the direction of travel of the sheets.

摘要： 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.
