Apparatus and method for positionally defined transport of sheets

An apparatus, in particular roll-type cross-cutter, for forming a shingled stream of underlapping or overlapping sheets, in particular paper or cardboard sheets, the apparatus having:

• a transport device for transporting sheets;
• a shingling device for underlapping or overlapping the sheets in regions;
• a braking device which is situated downstream of the shingling device in a transport direction of the sheets and which serves for braking shingled sheets, in particular by forming a braking gap for the passage of sheets that have been brought together in shingled form;
• a cross-cutting device which is positioned upstream of the shingling device and which serves for cutting a material strip into individual sheets;
• a first suction intake section provided upstream of the shingling device and extending between the cross-cutting device and the shingling device;
• and
• a second suction intake section provided upstream of the braking device and extending between the shingling device and the braking device and which serves for sucking up and further transporting a trailing sheet in the shingled stream into the braking device;
• wherein between the first suction intake section and the second suction intake section and directly below the shingling device, a portion of a transport plane of the sheets is provided with no negative pressure or a less strong negative pressure in comparison to a negative pressure generated by the first and second suction intake sections.
