Definitions

  • This invention relates to a unit and a method for separating plugwraps and applying them to rod-shaped smoking articles.
  • the unit forming the object of this invention is applicable in particular in machines known as "filter tip attachment" machines 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 cigarettes of other kinds, such as, for example, electronic cigarettes which can be smoked by electronically heating the end of the cigarette opposite the filter.

  • cigarette is used to generally denote a plurality of products or smoking articles such as, for example, cigarettes, cigars, cigarillos and the like, provided with a filter.
  • a "filter tip attachment” machine receives a succession of equispaced cigarette segments from a cutting station located downstream of a forming beam of a machine which makes the cigarettes, known simply as "maker". After being cut into two segments of desired length, the cigarette segments are fed to a withdrawal conveyor by way of a plurality of rotary transfer conveyors, known as conveyor drums. After withdrawing the two cigarette segments, the withdrawal conveyor spaces them axially apart to make room for a double filter.
  • the group thus made up of two cigarette segments and a double filter is joined by a gummed plugwrap fed to the group by another drum and rolled around the group by a rolling device. Next, the group made up of cigarette segments, double filter and plugwrap is cut in half and fed to an outfeed conveyor drum.
  • the gummed plugwraps are made by feeding a paper web which is unwound from a roll and which, after being gummed, is cut into individual plugwraps transversely to its longitudinal direction of extension. Cutting may be performed by known means, such as, for example, a scissor cutter, an impact cutter or a sliding cutter, to divide the web into a sequence of plugwraps.
  • Each plugwrap typically has the shape of a rectangular patch which is wrapped round the double filter and at least a short stretch of each of the cigarette segments abutting against the double filter at either end.
  • Cigarettes of this kind are known from WO2016/156209 and preferably comprise a tear tab allowing the consumer to grip and partly remove the plugwrap.
  • advertisements and/or graphical effects for different marketing purposes can be applied on the removable portion of the plugwrap or the zone of the filter uncovered.
  • an at least partly removable plugwrap means that a flavourant or essence can be associated with the plugwrap to come into contact with the consumer's lips or be perceived by smell before, during or after smoking.
  • removing the plugwrap at least partly from the filter activates a new olfactory and taste experience for the consumer who may decide its intensity and the time when to enjoy it.
  • removing a small piece of plugwrap exposes to the air a specific part of the filter which has been previously treated with a coat of flavourant and which can come into contact with the consumer.
  • the Applicant has found that in order to separate the plugwraps from each other in such a way that after being rolled round the group they define a convenient tab-like grip profile which enables the consumer to grip it and partly remove the plugwrap, it is necessary to make at least one shaped score line.
  • the step of separating the plugwrap and making the shaped stretch would be excessively complex and/or slow relative to the high production speeds required. Moreover, the step of separating the plugwrap and making the shaped stretch would subject the cutting means to excessive strain, thus reducing their working life.
  • This invention therefore has for an aim to provide a unit for separating plugwraps and applying them to rod-shaped smoking articles which allows making plugwraps with a removable portion in an efficient and reliable manner.
  • Another aim of this invention therefore is to provide a method for separating plugwraps and applying them to rod-shaped smoking articles which is practical and effective and which allows improving the efficiency of the production process.
