Definitions
- the invention provides a trimming device for trimming a cigarette i2 filler stream supported by an endless band in a cigarette making i3 machine, said device comprising a first continuously movable part
- the invention also includes a trimming device for trimming a
- a suction band comprising a first continuously moving part
- the invention also includes a twin track cigarette machine
- the two movable parts are preferably both in the form of discs.
- the first disc has its axis of rotation lying above
- 35 second disc has its axis of rotation below the band, substantially parallel
- the lower disc is preferably larger in diameter than the
- the second disc may lie in a plane parallel to the s band, so that its relationship with the band and the tobacco is similar to 9 that of each of the trimming discs shown in the above-mentioned patent, ⁇ o except that the disc according to this invention would extend all the way ii across the tobacco filler stream. Removal of excess tobacco may be i2 assisted by means of a rotating brush-like member as described in the i3 above-mentioned patent. In contrast in the preferred construction i4 described above, the lower disc displaces the excess tobacco laterally is away from the tobacco remaining on the suction band, so that the i6 excess is able to drop under gravity without any risk of being retained by i7 the suction applied through the band immediately downstream of the is trimming device. i9 Examples of trimming devices according to this invention are
- FIG. 1 is a front view of one device
- Figure 2 is a section on the line ll-ll in Figure 1 ;
- Figure 3 is an enlargement of part of Figure 2.
- Figure 1 shows upper and lower discs 10 and 12, and a manifold
- the lower disc 12 has regularly spaced peripheral portions 12A
- 34 disc 10 has corresponding larger-diameter portions 10A which mesh
- This shaft has its axis parallel to the plane of a
- suction band 18 (shown more clearly in Figure 3) and at right angles to 1 the centre line of the suction band.
- the diameter of the lower disc 12 is slightly
- the discs 10,12 are driven at the
- suction level may be varied
- Figure 4 shows an alternative arrangement involving a disc 30
- the disc 30 has a purely circular edge ⁇ and extends below the filler stream.
- the 9 disc 34 has circumferentially spaced pocket-forming portions 34A, and ⁇ o excess tobacco is removed with the help of a rotary brush 38 formed a with inclined vanes 40; the brush may be positioned with its periphery i2 close to the general p lane of the disc 34, and be formed with i3 circumferentially spaced recesses to accommodate the pocket-forming i portions 34A.
- the trimming height is controlled by moving the disc 34 and brush i6 38 up and down, for example in response to a neucleonic scanner i7 detecting the density of the finished cigarette rod; alternatively, the disc is 34 and brush may be set at fixed heights and weight control may be i9 achieved, for example, by controlling the height of the band 36 (the
- the disc 30 may in each case have a diameter equal to or 3i approximately equal to that of the disc 34.
- the side rail supports the filler stream adjacent to the suction
- the disc 34 may be provided with
- the fins would be positioned and angled so as to
- FIG. 7 shows another possibility.
- This arrangement is similar to i2 Figure 4, except that the side of the filler stream during trimming is i3 supported by a band 42, in place of the disc 30 in Figure 4.
- the band i4 runs around pulleys 44 and 46 and is backed by a guide member 48.
- the filler stream is supported at its sides by i6 rails 50 and 52. Whereas the rail 50 is interrupted to allow the band 42 to i7 support the filler stream during trimming, the rail 52 is merely cut away to is allow the lower portion of the filler stream to be reached by the trimming i9 disc 34.
- a brush may be provided, as mentioned above, to project the
- the disc 34 may be formed with a pattern of apertures in
- weight control may, 3i instead of being achieved by vertical movement of the trimming device
- suction band result from control of the level of suction in the suction
- Dense ending may be achieved by locally compacting
- Figure 5 also shows a second rod-making track 54 parallel and similar to the arrangement just described.
- a disc 56 and band 58 are provided, in staggered positions with respect to the corresponding parts of the trimmer for the first track, and these form mirror images of the arrangement described above with respect to the first track.
- the trimming devices described in this application are particularly suitable for twin-track cigarette making machines and allow the two suction bands to be close together and at the same level.
