  • the increments of tobacco as measured by the drum 10 are delivered in spaced relation upon the cigarette paper web as the latter travels past the delivery edge of the wall 12 and then the web receives the normal supply from the chute 6, whereby the cigarette rod is formed with uniformly occurring irregularities in the density of the tobacco, so that when the rod is severed into cigarette lengths each cigarette will be formed with denser portions at its ends, the increments of tobacco, as will be understood, being delivered at the positions along the rod corresponding to the severance of the rod.
  • the spacing may be arranged to produce a rod having' denser portions corresponding to two cigarette lengths, so that the cigarettes will be produced having only one dense end.
  • the speed of rotation of the drum 10 may be such that the incrementiof tobacco as it is delivered to the cigarette paper web moves at substantially the speed of the web.
  • an oscillating surface or element 20 may be provided in the tobacco chute 21, into which the tobacco is showered.
  • the element is pivotally mounted at its upper end while its lower end extends into proximity but not in contact with the cigarette paper web 7.
  • the element oscillates in the direction of the paper web feed and is adapted to intercept a portion of the shower of tobacco and cause it to be delivered to the paper web in spaced heaps or waves.
  • the oscillations of the surface or element 20 may be effected by coupling it by a link 22 to any suitable actuating element or drive, such las eccentrics, cranks or the like.
  • the oscillating element will be timed to synchronize with the cut-01T device so that the heaps or waves of tobacco will correspond to the position of the cut whereby the cigarettes will be formed with denser end portions.
  • the oscillating element may comprise a chute or a spring steel member, or as illustrated diagrammatically in Figure 4, may comprise an endless travelling band 23 mounted on an oscillatable frame 24 and driven in any suitable manner.
  • '111e frame is coupled to a crank or eccentric by a link 22.
  • the auxiliary supply of tobacco adapted to form the added increments is delivered into the chute 5 and is received upon an endless travelling band or conveyor 25 which is supported upon spaced end rolls or drums 26, 27 mounted to rotate upon axes transverse to the direction of feed of the cigarette paper web.
  • the conveyor is provided with a series of spaced blocks 28, the conveyor intermediate such blocks being provided with perforations 29.
  • the conveyor is mounted between rside walls so as to form a suction chamber 30 into vwhich a suction pipe 31 projects such pipe being coupled to a pump or other suitable source of suction.
  • a bafe 32 within which the inner face of the conveyor 25 contacts, the arrangement being such that as the perforations pass the edge 32a of the baffle suction will be cut off and a shield 33 is provided concentric with the axis of the drum 27 and encloses the part of the conveyor which functions to convey the increments of tobacco.
  • the conveyor 25 may be driven intermittently or continuously.
  • tobacco from suitable carding mechanism is delivered or showered into the chute and is received upon the conveyor 25 within the space between a pair of blocks 28.
  • the tobacco is retained 4on the conveyor by the suction and is thus prevented from falling into a heap as the conveyor, passes around the drum 27.
  • the perforations -29 are covered whereby the tobacco is released and falls onto the travelling paper web 7or other travelling band so that the increment of-.tobacco is spread out to the desired amount on such webs. Any shreds of tobacco not adhering tothe conveyor as it passes around the drum 27 will be caught by the shield 33 and is delivered therefrom by the appropriate block 28 over the deliveryedge 33a.
  • a bucketed wheel maybe provided at the front end or the rear end of the chute, such wheel being mounted to rotate upon an axis transverse to the direction of movement of the cigarette paper web.
  • the buckets are filled with tobacco from vthe shower or from an independent supply and the buckets deliver the tobacco therein onto the cigarettev paper web at spaced points and thus provide spacedincrements of tobacco to the normal feed, whereby the desired variation of density is secured.
  • the bucket wheel may operate within the ends of the chute or in a separate compartment adjacent such ends.
  • auxiliary tobacco feed may be controlled in such a manner that instead f of delivering spaced increments which are distinct and separate from ,one another, a more or lessrcontinuous delivery may take place which, however, is such that it assumes a Wave-like form when on the band or web of paper, adapted to produce a cigarette rod having the denser and less dense por-tions.
  • the invention is not limited to the details set out above, by way of example, as such may be altered in various ways with a view to obtaining the adjustments in the tobacco feed necessary to produce the variations of density of the tobacco in the cigarette rod.
  • Tlhecombination with cigarette rod forming and cutting mechanism of means for successively providing said ⁇ mechanism prior to the formation of the rod With separated increments of tobacco for addition to the normal supply to enable said mechanism to produce supernormal dense rod portions at intervals timed to cause the cutting mechanism to sever the rod in the middle of the dense portions, said means includving anoscillating and traveling belt intercepting falling tobacco and delivering it to said mechanism in separated increments.
