- the density of the fibers can also 10 can be specified in the tobacco rod 15.
- FIG. 5 Another embodiment of the invention is shown in FIG. 5.
- the Wheel 25 does not have flattened areas 30, but the radius of wheel 25 is constant.
- the compressed areas 31 in the tobacco rod 15 are in the 5 exclusively by the application of Suction tape 11 generated with negative pressure via the suction bores 32 of the wheel 25.
- the wheel 25 lies on the suction belt 11 and exerts a slight pressure on it, causing the distance between the suction belt 11 is given to the trimmer wheels 21.
- Fig. 7 shows a third embodiment.
