Definitions

  • This invention relates to a machine and method for making rod-shaped articles for smoking (hereinafter “rod-shaped smoking articles”).
  • the 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.
  • tobacco-based material reconstituted, pre-treated, homogenized or cast-leaf tobacco
  • filter paper material 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.
  • the technical purpose which forms the basis of this invention is to propose a machine and a method 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 reducing the risk of entanglement and jamming.
  • a further aim of this invention is to provide a method for making rod-shaped smoking articles and which allows improving the efficiency and effectiveness of the production process by reducing or eliminating the risk of entanglement, tearing and jamming.

  • each longitudinal strip is connected at least to the longitudinal strip adjacent to it so that it is easier for them to be gathered and conveyed without tearing and without causing machine jams.
  • the shape of the longitudinal strips gives the smoking article a compact, cohesive filling; the presence of the joining portions guarantees the integrity of the strips while they are being processed and prevents detachment of each strip from the others.
  • the invention also provides a method for making rod-shaped smoking articles, comprising the following steps:
  • the step of cutting the web comprises making a plurality of longitudinal, broken cutting lines in such a way that two longitudinal strips which are transversely adjacent each other relative to the longitudinal feed direction remain connected to each other by at least one joining portion.
  • making a plurality of longitudinal, broken cutting lines makes it possible to define stretches by which the longitudinal strips are joined to each other in such a way that after they have been cut and while they are being gathered and conveyed, the strips do not get entangled or jammed in the machine and in such a way that the longitudinal strips made in this way are less subject to tearing since each strip is urged along by the one adjacent to it.
  • 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.
