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.
Claims7
Apparatus for the trimming and compression of tobacco for forming a cigarette rod, said apparatus comprising:
- conveyor means comprising a suction conveyor arranged for conveying on its lower face an endless stream of tobacco;
- compression means consisting essentially of a compression part disposed below said conveyor means, said compression part acting on said stream for forming cyclically distributed compression zones in which the stream is uniformly compressed throughout its thickness, each of said zones corresponding to a tip of a cigarette;
- and
- cutting means comprising a pair of rotating disks disposed below said conveyor means and downstream from said compression means, said disks having plane upper faces and circular peripheral edges defining a permanent zone of mutual contact acting solely as a cutter for portions of said stream lying between said edges.
