Definitions

  • ABSTRACT oli/THE DISCLOSURE A method and a means for the manufacture of tobacco foil in which a layer of fibres and tobacco dust is formed on a conveyor belt. In order to ensure that the dust settles or otherwise comes to lie ⁇ between the fibres on the belt, the fibres are caused to stand upright and on end upon the conveyor belt by the application of an electrostatic field.
  • the present invention relates to the arrangement of fibrous material and dust-like material in an elongated, flat formation, and more particularly to the production of tobacco foil from tobacco products.
  • the longfibred portion ⁇ was then mixed with aluminum hydroxide and then formed into a sort of paper on a paper-making machine.
  • the material was treated with a moistening agent, as is conventionally used in the production of tobacco.
  • the tobacco was worked in a liquid phase and the leaching-out of substantial components of the tobacco was therefore unavoidable. Although at least part of the liquid was used later in the procedure it was not possible to ensure that all the valuable tobacco components removed by leaching were restored, so as to be present in the final product. This was particularly so as regards the tobacco components responsible for aroma and flavor.
  • kwhole tobacco leaves, portions of tobacco leaves, or tobacco leaves cut into strips were to have finely divided tobacco or tobacco dust applied to them and attached by the means of adhesives, the purpose of the process being to use waste or woody ribs or the like from the tobacco leaves in the final product.
  • adhesives such as galactomannan gum, for example, were used for forming tobacco dust into a thin foil.
  • One object of the present invention is to provide a method of arranging a fibrous material and a dust-like material in a flat elongated formation without the use of any adhesives which do not originate from the tobacco plant.
  • a further object of the invention is to provide such a method which does not involve the immersion of tobacco in a liquid phase.
  • a further object of the invention is to provide such a process which will make possible the manufacture of tobacco foil from tobacco dust with only a minimum amount of fibrous material.
  • a still further object of the invention is to provide a process for producing a tobacco foil which is substantially the same as tobacco.
  • Yet another object of the invention is to provide a method which can be generally used for arranging a fibrous material and a dust-like material in a flat elongated formation which is of general applicability, that is to say, not restricted to tobacco manufacture.
  • the present invention therefore consists in a process for arranging a fibrous material and a dust-like material in a flat elongated formation including the steps of freeing the dry fibrous material of lumps in a lump-removing supply means, drawing the material onto a moving conveyor belt by means of an electrostatic field extending between the supply means and the belt, maintaining the fibres on the belt in an on-end position in a zone downstream from the supply means, so that the dust comes to lie between the individual fibres of the fibrous material, and compacting the fibrous and dust-like material, preferably by rolling it.
  • the elongated formation of fibrous and dust-like material can be slightly moistened before and/ or after compaction, or, alternatively, the w-hole process can be carried out in an atmosphere containing a suitable amount of moisture. This brings about a substantial increase in the tensile strength of the elongated formation produced.
  • the present invention also consists in an apparatus for forming an elongated formation of fibrous material and dust-like material, comprising an endless conveyor belt Iwith two parallel limbs, a lump-removing fibrous material supply means arranged opposite a particular limb of the conveyor belt, electrical lead means for maintaining an electrostatic field between the supply means and the conveyor belt, a plate extending along a portion of a particular limb of the conveyor belt downstream from the supply means for maintaining an electrostatic field along the particular limb, means for guiding dust-like material onto the conveyor belt limb opposite the field plate, and means for rolling the fibrous and dust-like materials to compact them.
  • the conveyor belt is grounded and the field plate and supply means are at a positive potential.
  • the field plate itself is preferably constructed as the means for guiding dust-like material onto the conveying belt and for this purpose is provided with holes directed towards the belt.
  • the removing of lumps from the fibrous material can be brought about by a rubbing or beating action.
  • the starting fibrous material can for example be regenerated cellulose, hydrated cellulose, native cellulose, or other forms of treated cellulose or tobacco fibres.
  • the electrostatic field maintained between the conveyor belt and the field plate preferably has a potential gradient on the Order of 1000-2000 volts per centimeter, so that if the spacing is l0 cm. the potential will be at least about 10.000 v. or, if it is 20 cm., 20,000 v.
  • the moistening before and/or after compacting which increases the tensile strength of the foil produced can be done with water with or without tobacco extract, or possibly a solution of a binding agent.
  • a binding agent can be a cellulose derivative such as CMC, MC methyl cellulose, ethyl cellulose, an alginate, pectin or galactomannans.
  • the dust be applied to the fibrous material while the fibrous material is on end. It is only important that the fibrous material be aligned with the field so that it is perpendicular to the conveyor belt, with the dust-like material lying between the fibres and held between them during and after the following compaction.
  • FIG. 1 is a sectional side elevation of an apparatus for carrying out the invention.
  • FIG. 2 is a similar view of a further form of apparatus for carrying out the invention.
  • reference numerals 1 and 2 denote rolls or rollers on which a conveyor belt 3 is supported.
  • the direction of movement of the conveyor belt is indicated by arrow 4.
  • a series of intermediate support rolls are Provided.
  • the rolls 2 are preferably grounded electrically.
  • the conveyor belt 3 is preferably made from a synthetic resin, or is of a material coated with a synthetic resin. It is also possible tomake the belt of metal, although this has been found to be less suitable than synthetic resin.
  • a lump-removing comminuting supply means 5 for the fibrous material to be placed on the belt.
  • This comprises a series of rolls 6, which may be provided with knives.
  • the fibrous material freed of lumps emerges from the bottom end of the supply means 5, passes onto the conveyor belt 3, and travels in the direction denoted by arrow 4.
  • the supply means 5 is maintained at a positive electrical potential while the conveyor belt 3 is grounded through the end roller 2, so that there is an electrostatic field between the supply means and the conveyor belt.
  • the fibrous material emerging from the outlet end of the supply means 5 drops onto the conveyor belt and passes underneath a field plate 7.
  • the later carries a positive potental of, for example, 10,000 to 20,000 volts, which creates an electrostatic field between the plate and the conveyor belt 3.
  • the field plate 7, which is electrically coupled with the supply means 5, has a plurality of holes 8 extending through it which enables it to serve as a sieve for the sprinkling of the dust-like material 9 onto the fibrous material already -on the belt 3, although other means can be provided for placing the dust-like material onto the fibrous material, for example by means blowing it in from the side.
  • the strength of the web or elongated formation 13 can be substantially increased if the formation is moistened additionally, as for example at position 11.
  • the lump-removing supply means 5 is arranged below the lower run of the conveyor belt 3, and, as was the case with the first embodiment of the invention, is connected electrically with the field plate 7 extending downstream thereof.
  • introduction of the dust-like material is carried out by means of nozzles 15 spaced along the length of the field plate and disposed between it and the conveyor belt, which operate to blow the dust-like material onto the belt from the side.
  • the electrostatic lfield causes the dust-like material to pass upwardly between the upright fibres 10 and against the belt 3, in which position this material will then remain so long as it is under the influence of the field.
  • the fibres and the dust-like material leave the field they are compacted together by a pair of opposed rollers 16, one of which is on each side of the belt, at position 17.
  • the rollers 16 thus compact the material into an elongated fibre web or formation similar to that seen in FIG. 1 and designated by the numeral 13.
  • an elongated web-like formation produced by the apparatus consists of from five to ten percent fibrous carrying material and approximately ninety percent dust-like material, that is to say, in the production of tobacco foils the proportion of tobacco dust can be at least ninety percent.
  • a counterelectrode positioned opposite the field plate 7 can be proiclled, located between the upper and lower runs of the
