Abstract (en)

[origin: WO2012126588A1] The invention relates to a method for producing filter plugs from filter stems having a predetermined filter stem length. The method is characterized in that the filter stems are transported trans-axially on a first pushing/cutting drum (20) interacting with a first cutting device (24) disposed on the first pushing/cutting drum (20) and comprising pushing means for longitudinally pushing filter stems on the first pushing/cutting drum (20), and then on a second pushing/cutting drum (30) interacting with a second cutting device (34) disposed on the second pushing/cutting drum (30) and comprising pushing means for longitudinally pushing filter stems on the second pushing/cutting drum (30), and a) both cutting device (24, 34) are operated for cutting the filter stems, wherein the filter stems are cut by means of the first cutting device (24) on the first pushing/cutting drum (20) and by means of the second cutting device (34) on the second pushing/cutting drum (30) into three filter plugs each of a first predetermined filter plug length, or b) one of the two cutting devices (24, 34) is operated for cutting the filter stems and the other cutting device (34, 24) is not operated, wherein the filter stems are cut by means of the one operated cutting device (24, 34) on the pushing/cutting drum interacting therewith into two filter plugs each of a second predetermined filter plug length.
