  • Apparatus for trimming and compression of tobacco
    Patent number: 5003996
    Abstract: Combined in a very compact unit (1) are means for trimming and for compressing tobacco during the cycle of formation of a cigarette rod. Dense-end disks (3, 4) are made up of beveled circular cutters in contact (at 21) at their peripheries. The trimmed tobacco drops by the force of gravity into a discharge container without being subjected to buffeting by extraction brushes. The cyclic compression of the cigarette rod at locations corresponding to the tips of cigarettes is carried out by a rotary cam (7) placed slightly upstream and below the dense-end disks.
