Definitions

  • This invention relates to a machine for making rod-shaped articles for smoking (hereinafter “rod-shaped smoking articles”).
  • rod-shaped smoking articles referred to herein are articles made from a web of material for the tobacco industry such as, for example: tobacco-based material (reconstituted, pre-treated, homogenized or cast-leaf tobacco), filter paper material or PLA.
  • These articles can be used in the tobacco industry to make traditional filter cigarettes, that is, cigarettes which can be smoked by burning the end of the cigarette opposite the filter, or electronic cigarettes such as, for example: heat not burn, electronic-cig, mixed electronic-cig and tobacco.
  • a web of material for the tobacco industry is cut lengthways into longitudinal strips which are then gathered and wrapped in a web of paper to form a continuous rod containing a plurality of longitudinal strips placed side by side. It is then possible to obtain a plurality of articles from the rod, each comprising a plurality of longitudinal strips placed side by side.
  • document US 4,889,143 describes a machine and a method for making rod-shaped smoking articles where two webs of material for the tobacco industry are unwound from rolls and fed to a cutting station configured to cut the webs into strips. The strips thus obtained are then gathered and sent to a garniture conveyor to make a continuous rod of material for the tobacco industry which can be cut to obtain a plurality of rod-shaped articles.
  • a cigarette filter material is prepared by slitting a sheet into a plurality of equal width strips by means of rotating intermeshing grooved rollers and restraining the strip at the exit side of the nip to prevent its free egress from the nip, whereby the strip is corrugated into the vicinity of the groove of the roller in a substantially regular series of oppositely-directed parallel folds transverse of the width of the strip.
  • the longitudinal strips wrapped in the paper web to make the continuous rod do not form a structurally stable element because the strips are not disposed in such a way as to fill the rod correctly, resulting in gaps or zones of different density.
  • the technical purpose which forms the basis of this invention is to propose a machine for making rod-shaped smoking articles to overcome one or more of the above mentioned drawbacks of the prior art.
  • this invention has for an aim to provide a machine for making rod-shaped smoking articles and which is capable of making longitudinal strips which allow the smoking article to be effectively filled.
  • this invention provides a machine for making rod-shaped smoking articles according to claim 1.
  • Said machine comprises in particular:
  • the machine also comprises forming means for making a plurality of longitudinal easy folding zones in such a way that each longitudinal strip has at least one longitudinal easy folding zone.
  • the longitudinal strips according to this invention can be easily folded during the steps of gathering and conveying so that adjacent longitudinal strips adhere effectively to each other, thus making a continuous stream and a continuous rod of high quality in which the longitudinal strips are closely pressed together and optimally compacted to fill the smoking article uniformly.
  • a method for making rod-shaped smoking articles comprises the following steps:
  • the method also comprises a step of forming a plurality of longitudinal easy folding zones in such a way that each longitudinal strip has at least one longitudinal easy folding zone.
  • forming a plurality of longitudinal easy folding zones makes it possible to improve the manufacturing quality of the smoking articles.
  • the numeral 1 denotes in its entirety a machine for making rod-shaped smoking articles and hereinafter referred to simply as machine 1.
  • the machine 1 comprises unwinding means 2 for unwinding at least one roll 2a of web 100 of material for the tobacco industry such as, for example, tobacco based material, filter paper or PLA.
  • the web 100 is adapted to be unwound along a longitudinal feed direction, indicated by the arrow X in Figure 1 .

  • the machine 1 comprises first cutting means 3 for cutting the web 100, located downstream of the unwinding means 2, and configured to receive and cut the web 100 in such a way as to create a plurality of longitudinal strips 101 along the longitudinal feed direction "X".
  • the first cutting means 3 comprise at least a first roller 4 and a second roller 5 acting in conjunction with each other and configured to create the plurality of longitudinal strips 101 on the web 100 sliding between the rollers 4, 5.
  • the first roller 4 comprises a plurality of cutting discs 6, preferably rotary (alternatively, they may be fixed, while the roller 4 rotates) configured to make longitudinal strips 101 having straight or wavy or zig-zag edges 102.
  • the cutting discs 6 create longitudinal cutting lines defining the edges 102 of the longitudinal strips 101.
  • each cutting disc 6 has a straight or wavy or zig-zag cutting profile.
  • each cutting profile of one cutting disc 6 and the next corresponds to the width of the longitudinal strips 101.
  • making longitudinal strips with wavy or zig-zag edges 102 allows improving the cohesion between the longitudinal strips 101 during subsequent processes so as to prevent material from falling out of the tips of the articles.
  • first roller 4 is provided with cutting discs 6, according to the invention
  • second roller 5 is "plain”: that is to say, it has a substantially flat surface, without grooves or other cutting discs 6.
  • the machine 1 comprises forming means 7 for making a plurality of longitudinal easy folding zones 103 in such a way that each longitudinal strip 101 has at least one longitudinal easy folding zone 103.
  • the longitudinal easy folding zones 103 allow improving the step of gathering and conveying the longitudinal strips 101 which can be folded more easily so as to make rod-shaped smoking articles which are more compact and cohesive, with better filling uniformity.
  • the longitudinal easy folding zones 103 allow weakening the structure of the material so it can be folded more easily during the subsequent step of gathering.
  • the forming means 7 for making a plurality of longitudinal easy folding zones 103 can be disposed upstream of the first cutting means 3.
  • the forming means 7 for making a plurality of longitudinal easy folding zones 103 are located on at least one between the first roller 4 and the second roller 5 and comprise at least one between:

  • the first roller 4 is provided with cutting discs 6 whose cutting profiles are straight, with two alternately interposed reduced diameter scoring discs 9, whilst the second roller 5 is of the plain type so as to make longitudinal strips 101 of the type shown for example in Figure 4C , where each longitudinal strip 101 has two easy folding zones 103 made on the top side of the web 100 to facilitate folding of the longitudinal strips 101 themselves.
  • each longitudinal strip of this invention has at least one longitudinal easy folding zone.
  • the machine 1 also comprises gathering and conveying means 10 configured to gather and convey the longitudinal strips 101 from the first cutting means 3 to create at least one continuous stream 100'.
