Definitions

  • This invention relates to a process and an apparatus for the application of a cover on a cigar filler through application of a mass consisting of particles of tobacco and a solvent solution onto the tiller and a subsequent evaporation of the solvent.
  • cigars have already been known which have in place of the customary cover leaf or wrapper, a mass applied to the filler, wherein the applied mass consists of a mixture of a cellulose ester solution, especially an acetyl cellulose solution, with finely powdered tobacco.
  • the applied mass after evaporation of the solvent, will form a coating on the filler, which coating is to take the place of the rolled-on cover leaf or wrapper.
  • the application of the mass on the cigar filler may, according to this German patent, be accomplished by hand or through any kind of device, thus, for example, through submerging of the cigar filler into the applied mass or else by spraying on or painting on of the mass onto the cigar filler.
  • the process according to the present invention has for an object to provide the filler to be coated with a layer of the applied mass, in the desired thickness, in an atmosphere of vapors of the solvent which is contained in said applied mass, and that one then expels the solvent.
  • the application is accomplished by submersion of the fillers into the mass and that 'one then allows the fillers to drip in the atmosphere of the solvent.
  • the time of submersion should be within the time limit of one minute, and the dripping time should be within the time limit of three minutes. However, one can either use less time or more time and this will depend entirely on the quality and consistency of the applied mass.
  • the drying of the coated filler is accomplished in the air, preferably with some heated air.
  • the application of the cover by submersion of the fillers into the applied mass is particularly attractive because as far as the process is concerned and the apparatus, it is not at all complicated.
  • the applied mass is hard to spray becaues of its viscosity and because of the contents of solid tobacco particles, and the painting of the mass on the cigar filler, if not accomplished by hand, presupposes complicated painting devices which are prone to breakdowns.
  • the method of operation according to this invention is also applicable to this type of application of the mass onto the cigar filler, since here too one must still count with the flowing off of the excess quantities of the mass applied and one must still prevent the formation of a skin or the solidification of the drops as they are running ofi.
  • solvents used for the applied mass will depend on the binder. Since tobacco leaves will swell under the influence of water and thereby experience changes of shape, one will give preference to organic anhydrous liquids, where a swelling of tobacco would not occur. Solvents whose vapors are heavier than air are particularly well suited, in order that one could more easily produce and maintain with them the desired gaseous atmosphere.
  • cellulose ether such as methyl cellulose or ethyl cellulose
  • methylene chloride will be particularly suitable as a solvent, prehaps in a mixture with methanol.
  • chloroform would be suitable as a solvent, for the acetone soluble cellulose hydroacetates, acetone or mixtures of acetone and methyl or ethyl alcohol.
  • All film forming substances are pertinent as binders for tobacco particles, which substances are soluble in certain solvents. They must be unobjectionable physiologically and naturally they must not impair the tobacco taste while burning.
  • the tobacco particles in the applied mass should not be too fine.
  • the addition of fiber-shaped tobacco particles has proven particularly favorable, as could be obtained in a grinding mill with a ,5 mm.-slot. Crudely powdered or fiber-shaped tobacco particles will lead to a cover layer of greater strength and toughness than would finely ground material.
  • the device according to the invention for the application of a cover leaf by submersion of the cigar filler in accordance with a process according to the invention has been characterized by a closed chamber with lateral and upper walls, an entrance opening, an exit opening and a floor tub, which is filled at least in one section with the applying mass at a height corresponding to at least the submersion depth, as well as by a device for the submersion of cigar fillers at the above mentioned section and an arrangement for the transportation of the submerging fillers from the entrance opening to the submersion device, as well as for the transportation of the submerging fillers from the submersion device through the chamber to the exit opening.
  • needles As a holder for the cigar fillers during the accomplishment of the process according to the invention, needles have proven themselves as particularly suitable. It is best to unite these needles in the form of needled boards, and these again can be combined into fields or groups and can be handled in larger units.
  • the cigars will be placed on the needles with the end to be lighted, which can be accomplished either by machine or by hand.
  • the cigar fillers are not to touch each other, in order to make possible the formation of the cover sheet on each filler without disturbance.
  • the submersion section of the floor tub has been developed as a special vessel.
  • the submersion device consists either of one element which lowers the cigar fillers in their support into the submersion vessel, or else in a lifting device which will lift the submersion vessel to a point toward the cigar fillers heldconstantly as to height, whereby the latter Will dip into the applying mass.
  • the shape of the floor tub may be constructed in such a manner that the material dripping off from the submerged fillers will flow back automatically into the submersion vessel.
  • a pumping arrangement provided which will move back the material that has dripped down from the lowest spot of the bottom tub into the submersion vessel. This pumping device will thus simultaneously keep the applying mass in motion, as a result of which sedimentation is prevented.
  • a stirring apparatus instead of the 4 above arrangement in the submersion vessel or in addition to it, a stirring apparatus.
  • the floor tub may be uniform across its whole length, and in that case it must be filled everywhere to the required height with the applying mass. Then a special application vessel will become unnecessary and the transportation arrangement may be constituted by one single conveying chain or similar object, which will run from theentrance opening to the submersion device or from the submersion device to the exit'opening of the chamber.
  • This conveying chain will then run in such a manner that it will transport, on the one hand, the cigar fillers on their support from the entrance to the exit opening of the chamber and that, on the other hand, it will move them vertically in such a manner that the cigar fillers are dipped into the application mass at the entrance side of the chamber, so that they are kept in said application mass for the desired time and they are then pulled out again, and then transported above the application mass, so that the surplus may drip off.
  • the conveying of the submerged fillers from the submersion device to the exit opening may be accomplished horizontally orobliquely. During the upward conveyance one must make sure that the material dripping off from preceding fillers will not drop onto the succeeding fillers.
  • the drawing shows a longitudinal section through an apparatus or plant for the application of the cover leaf, according to-the invention, by dipping the cigar fillers into the application mass.
  • a usual cigar comprises a filler which is composed of scraps of tobacco leaves and possibly small stems in a mass.
  • the filler is rolled in an inner or first tobacco leaf or sheet of tobacco foil and this inner leaf with the fille is known as a roll.
  • the roll is rolled in an outer or second tobacco leaf, the so-called wrapper.
  • the dip coating technique to which the invention relates,
  • the roll is coated with a film of tobacco particles and a suitable binder, instead of being wrapped in a separate wrapper. Since the roll which in thed rawing is referred to by the reference character 11, in any case carry the inner tobacco leaf there is no substantial danger of falling from the conveyor 10. The inner wrapping of course must not be deteriorated by the solvent which is contained in the coating mixture.
  • the cigars equipped with a cover leaf are placed on pin studded boards with the end that is to be lighted. Twenty-six cigar fillers, as shown, each are united" in double rows on one pin studded board. Ten pin studded boards each are combined into one group and are pushed through the opening 3 by means of the conveying arrangement 10, onto the submersion device 8, 8a.
  • the entrance opening 3 is closed by means of a flap that can be operated rapidly, but it can also be developed in the form of a sluice, in order to prevent te escape of vapors of the solvent.
  • a slight underpressure can be maintained for the same reason by means of a blower, but only insofar as one has made sure that no substantial quantities of air will be sucked in from the outside.
  • a submersion vessel 8a At the entrance side of the chamber 1, there is a submersion vessel 8a, and this vessel is filled with a liquid which is composed as follows:
  • the tobacco powder may be obtained through tearing up of tobacco leaves in a grinding mill whose slot had been adjusted to 100 mm.
  • the structure of the tobacco particles is fibrous. According to its saturation steam pressure, the solvent will fill the inside space of the chamber 1 with its vapors.
  • the hoisting or lifting cylinder 8 will lower the pin studded boards resting on the rails 8b as one united group into the vessel 8a, so that the cigar fillers will be ubmerger entirely into the mass.
  • the lifting cylinder there may also be used a cable line.
  • next rail group 10 will be prepared.
  • the new rail group 12 which had been pushed by mechanical operation, will replace the rail group 9 which had in the meantime been immersed, so that the next rail group will be suspended above the container of liquid.
  • the next rail group 12 will not be pushed in prior to the completion of the submersion process.
  • this rail group 9 pushed onto a conveyor chain 7, which is operated electrically, and which will transport this rail group 9 within a period of about three minutes up to the opening 4.
  • the dripping time will be adjusted by synchronization of the transportation speed with the length of the charm her, which here amounts to about 500 cm. height and width of the chamber will amount to about 100 cm.
  • the pin studded boards are subsequently stood up in a wind channel (not shown), in such a manner that the cigars will stand in this wind channel facing upwards.
  • the pin studded boards move on a conveying chain for a period of about minutes through this wind channel through which heated air will move (about +3 C. above the wind channel, the cigars will dry. Subsequently the cigars are powdered, packaged and made ready for shipment according to the customary method.
  • a process for providing a cover on cigar rolls comprising dipping the rolls into a mass of tobacco particles and a solvent solution including a cellulose derivative binder, removing the rolls from said mass, permitting the excessive amount of particles and solution to drip off and then holding the rolls in an atmosphere which is substantially saturated with solvent vapours permitting the evaporation of the solvent from said coating whereby drippingoff is substantially completed so that a solvent-wet and substantially non-flowable coating of tobacco particles and binder is formed on the rolls, and drying the coated rolls outside of said atmosphere.
  • An apparatus for applying a cover on cigar rolls comprising a substantially closed chamber casing, having an entry opening in one end of the chamber casing, and an exit opening adjacent an opposite end of the chamber casing, a first tank near the entry opening of the casing and mounted in the casing, a trough-like container mounted in the chamber casing adjacent the tank, means to dip suspended cigar rolls into the tank, and conveying means to convey the dipped cigar r-olls through a space in the chamber casing above the trough-like container and finally to the exit opening, said trough-like container sloping toward a second tank for receiving excess solvent deposited on the trough-like container, means for returning solvent from said second tank to said first tank and means for substantially preventing the entry of air through said openings into said chamber.
