<p><P>PROBLEM TO BE SOLVED: To provide a cross cutting device for making a cutout (34) from a flat material web (30) moved in a conveyance direction (T), and an operation method corresponding to the cutter. <P>SOLUTION: The cutter has two cross cutting units (10 and 20) each having a fixed blade (12) and a rotary blade (16) provided on a rotary element (14), and the units (10 and 20) are placed at a distance from each other in the conveyance direction (T). A second rotary element (24) can be coupled to a sucking device so that the cutout (34) is at least temporarily fixed onto the second rotary element (24) when in use. With the invention, the rotary element (24) has a plurality of zones (60, 62 and 64) along its circumferential surface, and sucked air can serve individually or in combination for the plurality of zones to fix the cutout (34) in various formats. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
