Abstract (en)
[origin: WO2020048907A1] The invention relates to a separation device (12) for separating a flat web (6) into a plurality of strips (14), comprising a first cutting roller (30), which is rotatable about a first cutting roller axis (32), and a second cutting roller (34), which is rotatable about a second cutting roller axis (36) parallel to the first, the first and the second cutting rollers (30, 34) each comprising a plurality of blades (42) which interact with one another. The first and/or the second cutting roller (30, 34) are/is embodied as intermittent cutting roller (40), wherein all blades (42) of the intermittent cutting roller (40) each comprise at least one recess (44), which interrupts a cutting edge of the blade (42), the recesses (44) in the blades (42) of the intermittent cutting roller (40) being arranged along a helix (461, 462).
