Definitions

  • the invention relates to cigarette papers for rolling (RYO).
  • the object of the invention is to provide cigarette papers for rolling to limit the levels of tars and nicotine inhaled by the smoking.
  • a known means applied to industrial cigarettes to reduce the rates of inhaled tars is to increase the air permeability of the envelope of the cigarette, either by increasing the porosity of the paper used.
  • each strip of paper is perforated in a range between the mouthing zone and the end of the butt, relative to each end of the sheet.
  • the leaves are perforated either before or after the cutting step.
  • each band is perforated of paper at regular intervals as it progresses along two perforation patterns and for each pattern, the perforation interval is equal to the length of a leaf.
  • Each perforation pattern is made in a paper strip preferably at a distance of between 13 and 27 mm from a line of chopped off.
  • 13 mm is the average length of "Mouthing" and 27 mm is the length of the cigarette butt obtained after smoking.
  • the advantage of this technique is that it allows to obtain sheets of cigarette paper with a pattern of perforation at one distance between 13 and 27 mm from the edge. These perforations lead to not only a decrease in smoke yields, but also a constant ventilation of the cigarette during smoking. This breakdown constant allows to maintain a "taste” as constant as possible, what that is the length of the cigarette smoke.
  • the perforation patterns are lines. Paper strips are perforated along lines transversely to the running direction of the bands.
  • An area comprising a perforation pattern has a permeability to air preferably between 2 and 5000 CU (Units CORESTA).
  • the invention also proposes a sheet of paper for cigarettes to rolling obtained by the implementation of the previously defined method.
  • the invention further relates to a battery manufacturing machine or notebooks of rolling paper sheets, including means for unrolling at least one strip of paper, means for cut each strip into sheets, means to form piles or notebooks, characterized in that it includes means for punch each strip of paper at two zones located on each side and other and close to the cut lines.
  • FIG 1 there is shown a roll sheet for roll of "normal" format, that is to say having a length L of 70 mm and a width I of 38 mm.
  • the paper used is a conventional paper for this type of application having a mass of between 10 and 30 g / m 2 .
  • the sheet 10 has a longitudinal strip of rubber.
  • the X axis is the axis in which the paper is folded to be entangled as shown in Figure 3.
  • Figure 2 shows a rolled cigarette 20 made from the sheet 10 of Figure 1.
  • the sheet 10 was rolled in the width direction and the edges were glued by the gum thread 5 to form a cylinder.
  • Zone 1 corresponds to the mouthing zone, this zone 1 extends from the edge of the cigarette over a length L 1 of about 13 mm.
  • Zone 2 corresponds to the cigarette butt obtained after smoking, this zone 2 extends from the edge of the cigarette over a length L 2 of about 27 mm.
  • Zone 3 corresponds to the area of cigarette consumed during smoking.
  • Zone 4 is the area in which perforations, this area 4 is defined as the part of the cigarette located between the mouthing zone 1 and the end of the butt.
  • perforations P of the rolling paper following two transverse lines near each edge.
  • a line of perforation is necessarily found in each zone 4.
  • One of these zones 4 not being consumed, it allows to ventilate the cigarette during the entire duration of smoking in zone 3.
  • transversal lines In the example illustrated in FIG. 1, it has been chosen to produce transversal lines, of course other perforation patterns can to be chosen. For example, it is possible to make double transverse lines so as to lessen the paper in the longitudinal direction.
  • each zone 4 containing a pattern the perforation will preferably be between 2 and 5000 CU (unit CORESTA).
  • FIG. 4 diagrammatically shows the steps of FIG. manufacturing process of stacks of 50 sheets of paper for cigarettes roll entangled.
  • the strips 7 of papers are brought in parallel and folded in length. They are then entangled and then grouped together between two rollers 8 so as to form a flange 9. Lines transversal perforations are made perpendicular to the direction scrolling paper.
  • the bead 9 is then cut into piles of 70 mm long sheets in step C.
  • a worm 11 allows to eject the entangled piles.
  • This method can be applied to the manufacture of notebooks in which leaves are simply superimposed. In this case, we do not do not perform the step of entangling the paper strips before step consisting in grouping the coil strips 9 between the two rollers 8.
  • Performing the perforation step P just before step C of cutting has the advantage that areas of least resistance appear only at the end of the manufacturing process of batteries or notebooks. In this way, the risks of tearing are eliminated.
  • FIG. 5 shows a strip of perforated paper 7 making it possible to produce sheets similar to the sheet 10 shown in FIG. 1.
  • the cutting lines C are the lines according to which the strip 7 will be cut so as to form leaves, they are spaced apart by an interval equal to the length of the sheets L.
  • the perforation transverse lines P are made perpendicular to the direction of travel of the paper with successive intervals x 1 and x 2 .
  • x 1 must be between 26 and 54 mm to be located near a section line in a zone 4 as defined in FIGS. 1 and 2. For example, an interval x 1 of 40 mm and x 2 of 30 mm. In this way, the perforation lines P are located at 20 mm on either side of the cutting lines C.
  • the method described above can be suitable for all sizes of stacks of entangled leaves or notebooks.
