Cross cutting device and method for operating such a cross cutting device

The invention relates to a cross cutting device and a corresponding operating method for manufacturing cut-out portions from a flat material web which is moved in a direction of transportation. The device has two cross cutting units which each have a fixed blade and a rotating blade arranged on a rotational element, and said cross cutting units are spaced apart from one another in the direction of transportation. The second rotational element can be connected to a suction device in such a way that in a case of application the cut-out portion is at least temporarily secured on the second rotational element. According to the invention, the second rotational element has, along its circumferential face, a plurality of zones, to which suction air can be applied individually and/or in combination, in order to secure cut-out portions of different formats.
