Definitions

  • EP 3 381 303 A1 also discloses a method for producing at least double-layer tubular strands for the tobacco processing industry. For this purpose, two strips of material, of which at least one is glued, are brought together in an offset manner, so that a tubular strand is formed.
  • An interruption of the glue line within the meaning of this application is to be understood as a complete interruption of the respective glue line. This means that areas with smaller amounts of glue or a merely tapering glue line do not constitute an interruption within the meaning of this application.
  • the invention has recognized that remaining glue on the cut surfaces of the cut tubular or rod-shaped product leads to contamination of downstream machine components with residues of glue, which leads to unwanted stops of the machine and shortened cleaning intervals. This effect can be reduced or even completely prevented by synchronizing the first glue application device with the cutting device.
  • the rod or tube-shaped product thus has an improved quality and the system reliability properties of the device can be increased.
  • the use of the roller to form a glue line with glue-free zones offers particular advantages.
  • the formation of the glue-free zones can take place, for example, in that glue is applied to the roller only in sections by appropriate control and/or regulation of the nozzle.
  • the roller can be used to reliably depict the change between glued and glue-free zones, i.e. smearing or running of glue into areas that are actually intended as glue-free zones can be prevented by interposing a roller between the nozzle and the base material strip .
  • the arrangement of the glue-free zone at the first and/or at the second longitudinal end means that these ends can be manufactured without the interfering influence of glue.
  • tubular or rod-shaped products are cut with the cutting blade of a cutting device is shortened to the desired length.
  • the cut through a glued zone can lead to the so-called “black particles" remaining on the product ends formed by the cut.
  • glue on the ends of the product can soil any machine components that are used to further process the product.
  • the longitudinal axial extension i.e. the extension in the direction of the longitudinal axis, of the glue-free zone or zones extending over the entire cross section, starting from the first and/or the second end, is between 0.5 mm and 10 mm, more preferably between 1 mm and 2 mm, particularly preferably between 0.5 mm and 1 mm.
  • the tubular product without the additional material.
  • the strip of base material is glued to itself with glue.
  • production can also take place with the proposed device, in which case, for example, the second conveying device for conveying and adding additional material can then be omitted. Furthermore, the device is then set up so that the cut is made completely through a glue-free zone.
  • the proposed method can also be used to manufacture this product, with method steps c) and d) being replaced by the method step in which the strip of base material is shaped and glued to itself with glue so that a tubular intermediate product is formed.
  • FIG. 7 shows a schematic representation of a method for producing a rod or tube-shaped product
  • the device 1 comprises a first and a second conveyor device 4 and 5, a first glue application device 25, a joining device 11 and a cutting device 12.
  • the basic mode of operation of the device 1 is as follows:
  • the first conveyor device 4 moves a strip of base material 6 to the first glue application device 25, which is set up to apply at least one interrupted line of glue 8 to the strip of base material 6, so that in a longitudinal direction 7 of the strip of base material 6 the Glue line 8 glue-free zones 14 has.
  • the longitudinal direction 7 of the strip of base material 6 is aligned parallel to its longitudinal edge 19 .
  • the strip of base material 6 glued in this way is then conveyed to the joining device 11 .
  • an additional material 10 is conveyed by the second conveyor 5 to the joining device 11, where the strip of base material 6 is brought together with the additional material 10 and glued, so that a tubular intermediate product 2 is formed.
  • the glue-free zones 14 can be produced by the roller 26 , the outer surface of which has at least one depression at a point that corresponds to the glue-free zones 14 on the base material 6 . Accordingly, those areas of the outer surface of the roller 26 are wetted with glue through the nozzles 9, 23 and 24, which correspond to the areas of the base material strip 6 on which an application of glue is to take place.
  • the knife of the cutting device 12 only has to cut through the glued zone of the uninterrupted glue line 28 .
  • the sticking of the knife by glue residues can thus be further reduced in comparison to the exemplary embodiment according to FIG.
  • the nozzle 9 can have, for example, three separate outlet openings.
  • the interfaces 13 run through the glue-free zones 14 of all three interrupted glue lines 8, 27 and 28, so that the blade of the cutting device 13 does not have to cut through a glued zone. Accordingly, in the device 1 according to this exemplary embodiment, sticking of the blade of the cutting device 12 with glue that has not yet hardened can be completely avoided.
  • the base material strip 6 After the base material strip 6 has been glued by means of the first and second glue application devices 25 and 17 , the base material strip 6 is conveyed into the joining device 11 by means of the first conveyor device 4 . There, the additional material 10 in the form of a preferably cylindrical filter material is attached to the base material strip 6 by means of the interrupted line of glue 8 .
  • the shaping section 20 uses the shaping section 20 to reshape the strip of base material 6 around the additional material 10 until the strip of base material 6 overlaps in an overlapping area in which the uninterrupted line of hot glue 18 is also arranged. As a result, two overlapping end portions of the strip of base material 6 are bonded to each other via the continuous line 18 of hot melt glue.
  • the glue lines 8, 27 and 28 are formed by a biodegradable adhesive in this embodiment.
  • the product 30 can be manufactured by carrying out the method 22 shown schematically in FIG.
  • the longitudinal ends 31 and 32 with the glue-free zones 35 and 36 are then created by cutting through the glue-free zone 14; see, for example, Figure 3.
