SEPARATION DEVICE AND METHOD FOR SEPARATING A FLAT WEB INTO A PLURALITY OF CONNECTED STRIPS, AND DEVICE AND METHOD FOR PRODUCING A STRAND

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 rolleraxis (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). 本发明涉及一种用于将扁平幅材（6）分开成多个条带（14）的分离设备（12），其包括：第一切割辊（30），其能够绕第一切割辊轴（32）旋转；以及第二切割辊（34），其能够绕平行于所述第一切割辊轴的第二切割辊轴（36）旋转，其中，第一切割辊和第二切割辊（30、34）分别包括多个刀刃（42），所述多个刀刃彼此相互作用。第一切割辊和/或第二切割辊（30、34）被实施为间歇切割辊（40），其中
