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.
  • filters 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.
  • the Applicant has identified the need to make filter cigarettes provided with outer plugwraps which are at least partly removable.
  • 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.
  • Other examples of known solutions in this field can be found in documents WO2017/013105 , GB2246092 , EP3045055 and WO2014/064433 .
  • 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.
  • use of 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. For example, 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.
  • the numeral 100 denotes in its entirety a portion of a filter tip attachment machine, hereinafter referred to simply as machine 100.

  • the unit 1 is configured to separate plugwraps 2 from a web 3, preferably of paper, as will become clearer as this description continues, and apply them to rod-shaped smoking articles 101.
  • smoking articles 101 of the kind illustrated in Figure 6 that is to say, comprising a double filter 102 interposed between two cigarette segments 103 abutting axially against it end to end.
  • the invention is, however, also applicable to smoking articles 101 comprising a single filter abutting axially against one cigarette segment 103.
  • the unit 1 comprises a suction roller 4, adapted to rotate about its axis of rotation 4a in the direction indicated by the arrow F4, and feed means, not illustrated in the accompanying drawings, configured to feed the web 3 on the suction roller 4 along a feed path indicated by the arrow P.
  • the unit 1 is configured to separate a sequence of plugwraps 2 from the web 3 by cyclically generating a transverse cutting line T on the web 3, preferably perpendicular, as illustrated in Figures 5A and 5B .
  • the suction roller 4 is adapted to retain the web 3 and the sequence of plugwraps 2 by suction on its own external surface of rotation 4' while the suction roller 4 rotates.
  • the unit 1 also comprises transfer means 6 configured to transfer a succession of smoking articles 101 towards a suction roller 4 so that each plugwrap 2 is applied tangentially in known manner to a respective smoking article 101 at an applicator station 5.
  • the transfer means 6 comprise a conveyor roller 7 provided with peripheral suction flutes capable of retaining the smoking articles 101 and adapted to rotate about its axis of rotation 7a in the direction indicated by the arrow F7.
  • the peripheral speed of the suction roller 4 is preferably greater than the speed of the web 3 advancing along the feed path so that the plugwraps 2 cut off are spaced at a constant spacing.
  • the spacing of the plugwraps 2 coincides with the spacing of the smoking articles 101 feeding into the conveyor drum 7, so that each plugwrap 2 is applied correctly to the respective smoking article 101.
  • the suction roller 4 holds the plugwraps 2 by the ungummed side so that as each plugwrap 2 reaches a respective smoking article 101, that plugwrap is applied in "flag-like manner" to the smoking article 101.
  • the expression "flag-like manner” means that the plugwrap 2 adheres to the smoking article 101 only by a reduced portion of it; specifically, at the front edge of it. The rest of the plugwrap 2 remains lifted by known means not illustrated, which prevent the plugwrap 2 from drooping and sticking to the outer cylindrical surface of the conveyor roller 7.
  • the machine 100 comprises a rolling drum 8, disposed substantially tangent to the conveyor roller 7 and adapted to rotate about its axis of rotation 8a in the direction indicated by the arrow F8 and configured to receive the succession of smoking articles 101 with plugwraps 2 from the conveyor roller 7 downstream of the applicator station 5, and a rolling device 9 configured to wrap the plugwraps 2 round the smoking articles 101 provided with plugwraps 2 transported by the rolling drum 8.
  • the smoking articles 101 housed in the peripheral suction flutes of the conveyor drum 7 are transferred to the rolling drum 8 which moves them in the rolling device 9 in such a way as to roll the plugwraps 2 according to known methods.
  • the smoking articles 101 are rolled in the plugwraps 2 inside a rolling channel 9a while advancing along a longitudinal direction of travel of the channel 9a itself.
  • Feeding out of the rolling channel 9a are double cigarettes 104 made by the machine 100, that is, two cigarette segments 103 with a double filter 102 interposed between them and joined to each other by a plugwrap 2 wrapped round the double filter 102 and at least the end portions of the cigarette segments 103.
  • the double cigarettes 104 are first cut into single cigarettes 105 by cutting means of known type, not illustrated, and then subjected to further processing and operations of known type performed in cigarette making machines and not described here since they are outside the scope of this invention.
  • the unit 1 comprises first scoring means 10 configured to make cyclically and transversely on the web 3 or on the plugwrap 2 at least a first, preferably straight score line 11 defining at least one end segment T1 of the cutting line T and second scoring means 12 configured to make cyclically and transversely on the web 3 or on the plugwrap 2 at least a second, preferably shaped score line 13.

  • the first scoring means 10 and the second scoring means 12 may be disposed and adapted to be driven in such a way that the shaped score line 13 does not belong to the cutting line T.
  • the second scoring means 12 are configured to make at least one convex portion of the shaped score line 13 suitable for defining a grip tab L of the plugwrap 2.
  • the tab L can be easily gripped by the consumer to at least partly remove a portion of the plugwrap 2 corresponding to the respective part of the central portion X.
  • the central portion X is not gummed, allowing it to be removed by the consumer if necessary, while the opposite end portions Y are at least partly gummed to allow the plugwrap to be fixed to the double filter 102 and to the cigarette segments 103.
  • the web 3 is suitable for making a removable portion of the plugwrap 2, for example without the aforesaid gumming or with gumming suitable for removal.
  • the shaped score line 13 (as shown in Figure 6 for example) has a main direction of extension which is parallel to the cutting line "T" (and relative to which the shaped score line 13 may have undulations, protrusions, etc.). That way, the shaped score line 13 allows allow the plugwrap 2 to be partly removed along a tear direction perpendicular to the cutting line "T", that is to say, along a circumferential direction on the cigarette 105.
  • the web 3 preferably has at least one sequence of holes defining at least one line of weakness 14 substantially parallel to the lateral edges 3a of the web 3.

  • the plurality of blades 19 is configured like a plurality of blade pairs so that the end segments T1 are made simultaneously.
  • the plurality of blades 19 is configured like a plurality of blade pairs and the second scoring means 12 comprise a plurality of punches, each punch being interposed between the blades of a respective blade pair so as to make the at least one shaped score line 13 in such a way that the shaped score line defines a central profile T2 of the cutting line T interposed between and consecutive upon the opposite end segments T1 defined by the straight score line 11.
  • the central shaped profile T2 may be obtained, for example, using shaped blades.
  • a blade pair with an interposed punch advantageously allows making a scissor-like cut which simultaneously makes the opposite end segments T1 from the outside of the web 3 according to customary scissor cutting methods and, after simultaneously making the segments T1, allows making the central shaped profile T2 by means of a punch. This avoids the damage to the blade that would occur if the cut were made starting from a single lateral edge 3a in the end portions Y, then interrupted at the central portion X corresponding to the shaped score line 13 and resumed after the central portion X to make the opposite end portion Y.
  • the blade would have to resume the scissor cut which, since it is made by crossing the edges and bending the top blade, would lead to splintering of the blade, which would thus be unable to have starting guide edges because the cut must be complete and blended into the one made by the punch.
  • This invention achieves the preset aims by overcoming the above mentioned disadvantages of the prior art and providing the user with a unit for separating plugwraps and applying them to rod-shaped smoking articles and which allows efficiently making a smoking article provided with a plugwrap having a portion which can be easily removed by a consumer and allowing the removable portion to be used to meet a diversity of production requirements.
  • This invention also provides the user with a method for separating plugwraps and applying them to rod-shaped smoking articles and which guarantees maximum flexibility and operating and production versatility, allowing each plugwrap to be made with one or more shaped score lines at a cutting line or at a central portion thereof.
  • the filter tip attachment machine comprising the unit according to this invention advantageously allows improving the entire production process and the quality and variety of the rod-shaped smoking articles produced.
