Abstract (en)
[origin: EP0150473A2] In order to cut a moving tobacco sheet, particularly a reconstituted tobacco sheet, into pieces (12) whose width is less than the width of the sheet, a cutting roller is used which rotates about an axis arranged transversely to the direction of advance of the sheet. The cutting roller has at least one sawtooth-like cutter arrangement which interacts with an opposing cutter. Each of the cutting edges surrounding a cutting element of the cutter arrangement produces, in each working step, a non-linear cutting line (7') which, at two points set apart from each other, adjoins a section of the cut edge produced in at least one preceding working step. In this arrangement, one piece of the tobacco sheet is separated off in each case, and the cutting line (7') forms a section of a new cut edge. Preferably, one leg of each cut edge produced in a preceding working step extends in a linear manner in the direction of advance and is prolonged by a leg of the new cutting line (9'). <IMAGE>
