Definitions

  • This invention concerns improvements in or relating to an apparatus for making a continuous filler on a cigarette-making machine of the continuous rod type.
  • the loose tobacco stream so showered is irregular in that the quantity of tobacco varies from point to point.
  • Several proposals have previously been made for the purpose of reducing this irregularity, which affects weights of successive r cigarettes.
  • the apparatus which is employed according to the present invention to reduce inequalities along the length of the tobacco stream makes use of a known system which broadly consists of reducing the speed of the tobacco in a confining passage. It is thought that to obtain the best results it is desirable to ensure, as far as possible, that the reduction in speed shall take place in a part of the confining passage where the conditions are reasonably the same. For instance, it is desirable that the nature of the surfaces of the walls of the passage in the part where the reduction of speed occurs should be the same.
  • an apparatus for manipulating tobacco in the formation of a tobacco filler for a continuous cigarette rod on a cigarette making machine of the continuous rod type which comprises, means for feeding a controlled loose stream of tobacco forwardly into and through a guide whose interior tobacco-engaging surface provides a substantially straight throughway and encloses and confines the tobacco laterally and. is of a slippery nature and removing the tobacco from the guide at a slower speed than that at which tobacco is fed into it, the speed reduction being such that under the dimensional restraint of the said tobacco-engaging surface the aforesaid controlled loose stream is caused to close up, at least at its sparser portions, whereby the controlled loose stream is converted to a loose filler and the uniformity of distribution is improved.
  • an apparatus for manipulating tobacco in the formation of a tobacco filler for a continuous cigarette rod on a cigarette making machine of the continuous rod type which comprises, means for feeding a loose stream of tobacco forwardly into and through a confining passage, along part at least of whose length the tobacco-engaging surface which encloses and confines the tobacco laterally is of a slippery nature and provides a substantially straight throughway, the cross-sectional size of the passage being such that tobacco therein can form into a controlled loose stream, and removing the tobacco from said part of the passage at a slower speed than that at which it is fed into the passage so that the tobacco, before leaving the passage is formed into a loose filler in said part.
  • an apparatus for manipulating tobacco in the formation of a continuous cigarette rod on a cigarette making machine of the continuous rod type comprising, means for feeding a stream of loose tobacco into and through a confining passage in a part at least of whose length, the tobacco-engaging surface which encloses and confines the tobacco laterally is of a slippery nature, and provides a substantially straight throughway, removing the tobacco from said part of the passage at a slower speed than that at which it enters the passage whereby the tobacco speed is reduced as the tobacco moves along the passage, the ingoing stream of loose tobacco being of such volume per unit length that it contracts slightly in cross-sectional area as it enters the passage and under the dimensional restraint of the passage becomes a controlled loose stream,
  • the speed reduction being such that under the dimensional restraint of the passage the aforesaid controlled loose stream is caused to close up at least at its sparser portions, whereby the controlled loose stream is converted to a loose filler and the uniformity of distribution is improved and removing the slower moving loose filler from the passage and reducing its cross-sectional area and enclosing it in a continuous paper web to form a cigarette rod.

  • the cross-sectional area of the confining passage may increase in the direction of movement of the tobacco through the passage, to provide room for lateralexpansion of the tobacco stream as its speed becomes less.
  • the said surface which provides a slipping drive for the tobacco may be formed by a slippery surface of an endless band (e. g. a steel band) extending along the whole length of the passage and forming one of the said opposed endless surfaces arranged to move to feed the tobacco stream forwardly in the passage.
  • the said endless band may be arranged to move at a faster speed than the speed of the other of the said opposed endless surfaces.
  • the band is provided to feed the tobacco and as the surface is slippery the speed may be adjusted to give the desired result under any particular conditions.
  • the confining passage may be arranged to slope downwards in the direction of movement of the tobacco therethrough, the bottom wall of the passage having a curved portion at the outlet end of the passage to guide the tobacco stream into a substantiall horizontal path as it leaves the passage.

  • 1oosewh,en used herein in relation to a stream of tobacco refers to a stream of tobacco partly or; wholly confinedlaterally and in which the particles are relatively loosely arranged as distinguished from the relatively tightly packed condition found when such stream is reduced to the cross-sectional size of the cigarette rod.
  • a tobacco stream (of the appropriate weight per unit length) is compressed to cigarette rod size, the tobacco may be said to possess a relatively high degree of packing, cohesiveness and ability to impart an endwise pressure or thrust.
  • both a controlled loose stream and a loose filler both as defined below have an almost negligible ability to impart endwise pressure and little cohesiveness and accordingly not only should the frictional resistance offered by a confining passage in which the speed of the tobacco is to be reduced, be sufficiently low, but also the direction in which the tobacco moves should be straight, or substantially straight. Deviation should as far as possible be avoided or kept to a minimum so that the tobacco does not choke the passage. Any deviation which permits the tobacco when in a loose condition to suffer reduction in speed and yet pass without choking, is to be understood as coming within the expression substantially straight when used herein.
  • loose filler is used herein it is intended to refer to a stream of loose tobacco which has had its speed reduced in a confining passage.

  • the tape is supported at the sloping part on an angle member IS.
  • the lower part of the said sloping bottom wall consists of a steel plate 6, which is arranged in alignment with the sloping part 2A of thetobacco tape, and which has a highly polished surface. It will be seen from Figure 1 that the plate 5 almost touches the part 2A of the band 2, the purpose beinng to prevent the escape of tobacco, as far as possible, at the division between the two parts.

  • the band instead of being made of steel could be made of any other suitable material having a polished surface. It may move at twice the speed of the band 2 or at any speed found to be the best for achieving the desired result. Owing to the change in the direction of movement of the tobacco, it is found preferable to make the band I travel considerably faster than the band 2, to ensure that the tobacco is moving at the desired speed in the direction of the passage.

  • the depth of the stream formed in the trough by the shower is indeterminate, since it may be formed from long tobacco or from shorter tobacco and the relative moisture content has further influence on the manner in which the tobacco builds up in the trough itself.
  • the stream may be considerably deeper than the depth of the passage.
  • the cross-sectional area of the latter is suiliciently large (in the present case more than 2 /2 times the size of the cigarette rod) relatively to the size of the eventual cigarette rod which in the example under consideration is 8 mm., that the tobacco stream having the dimensions of the passage is still relatively loose, and is in a sufliciently loose condition for the purposes of the present invention.
  • the faster moving tobacco in the passage is a controlled loose stream and the slower moving tobacco is a loose filler.
  • the tobacco tape 2 exerts sufficient tractive force on the controlled loose stream to feed the latter into the passage and the steel band 7 although this is smooth and polished, co-operates with the tobacco tape to feed the tobacco, which under the dimensional restraint of the passage is now in the form of a controlled loose stream,
  • the tobacco as it leaves the passage in the form of a loose filler is received by the paper web which carries it beneath the tongue i 3 which compresses the loose filler to reduce it to the desired cross-sectional size, whereafter the paper web is folded about it and secured in the usual manner to form a continuous cigarette rod which into cigarette lengths.
  • tobacco is showered onto the tobacco tape on which takes the form of a stream of loose tobacco, and is fed by the tobacco tape into the upper part of the passage, the width and depth of which are sumciently great relatively to the size of the cigarette rod as toensure that the stream in the passage is a controlled loose stream.
  • the tobacco then passes down the passage, being driven between the two moving surfaces provided by the tobacco tape 2 and the steel band 1.
  • the tobacco then passes onto the lower or outlet portion of the passage, the bottom of which is now a smooth surface, and is delivered from that end as a loose filler onto the paper web.
  • the loose filler is given a very small compression by the portion of the steel band which passes around the lower roller, since this is 1 mm. closer to the paper than it is to the bottom wall of the passage at the outlet, though of course this compression is extremely light.
  • the plate 5 forming the bottom wall of the lower part of the passage is curved at 6A as mentioned above to guide the tobacco leaving the inclined passage onto the cigarette paper web
  • the part of the passage in which the stationary plate forms the bottom wall is made of such a length and thepath of the tobacco therethrough is such that it is thought that most, if not all the reduc tion of speed, and compacting, to substantially the extent desired, takes place in that straight portion of the passage.
  • the top slippery steel band provides a slipping drive for the tobacco which it is thought partly or wholly compensates for any increase of frictional resistance which may result from increase in pressure due to endwise compacting of the tobacco stream.
  • the weight per unit length of the loose tobacco stream before its speed is reduced is below the weight per unit length desired in the final cigarette rod, and the velocity of the fast moving stream is sufficiently above the speed of the cigarette paper web that all or nearly all the portions of the fast moving stream have a weight per unit length below that desired in the cigarette rod.
  • the amount of variation is usually well below 20% to 25% of the desired weight per unit length, and thus when the fast moving stream is moving at the speed mentioned above, namely about 40% faster than the cigarette paper web, in normal practice, there should be relatively few, if any, points where the stream of loose tobacco has a weight per unit length greater than that desired in the final cigarette rod.
  • cross-sectional area of the passage increases only slightly. In some cases, however, due to the condition of the tobacco, greater increase in the cross-sectional area may be required.
  • the tobacco Owing to the nature of the surfaces of the walls of the lower or outlet end of the passage, the tobacco easily slips over the smooth slippery surfaces of the steel band and the side and bottom walls, and so the controlled loose stream closes up on itself while still in its loose condition and thereby loses some of its irregularities.
  • the smooth slippery metal band forming the top wall of the passage does, it is thought, help to feed the tobacco through the lower part of the passage, especially wherever the pressure of the tobacco in the passage may increase, and thereby helps to avoid choking.
  • top and side walls of the passage and the condition of their surfaces are such that they provide slippery'surfaces on which tobacco slips more easily than it does on the usual cigarette paper.
  • An advantage of using a sloping passage as in the construction described is that the overall horizontal length of the device for a given length of passage is reduced as compared with a device having a horizontal passage.
