Definitions

  • the invention relates to a method for producing multi-segment filter rods of the tobacco-processing industry, wherein multifilter segments are assembled into at least one multi-segment filter strand and wrapped with a wrapping paper strip which is glued by means of a glue line in an overlapping region of the wrapping paper strip with itself and the coated Multifiltersegmenten, wherein a Part of the multi-segment filter cutting segments that are cut to cut multisegment filter rods from the multi-segment filter strand are apparatus for manufacturing multi-segment filter rods of the tobacco processing industry, comprising a multi-segment filter or group of multi-segment filters, a gluing device for gluing a multi-segment filter strand cover strip, a strand forming device for producing at least one of the wrapping paper strips enveloped A multi-segment filter strand from the multifilter segments and a trimming device for trimming multi-segment filter rods from the multisegment filter strand
  • filters made of segments of different materials are assembled, grouped and formed into a multi-segment filter strand which is wrapped with a wrapping paper comprising the filter segments assembled into a strand wrapped and held together. Subsequently, multi-segment filter rods of multiple use length are cut to length and further processed in a filter attachment machine.
  • the groups of Multifiltersegmenten or multi-segment filter rods can already be wrapped before the strand formation by a paper strip of low density to prevent falling apart of these groups together.
  • a cold glue and optionally also a hot glue, is usually applied to the wrapping paper. This is done with a contact nozzle.
  • the loss of the cutting segments takes place, in particular, in a subsequent step in a filter-making machine, for example at the location of a push-in drum, in which the cross-axially conveyed multisegment filter rods are accelerated longitudinally.
  • the adhesion and adhesion are not sufficient for slowing down the filters in the buffing drum.
  • the present invention has the object to increase the reliability of a corresponding machine and to prevent falling out of cut cutting segments from the cut to length Multisegmentfilterstäben.
  • This object is achieved by a method for producing multi-segment filter rods of the tobacco-processing industry, wherein multifilter segments are assembled to form at least one multi-segment filter strand and wrapped with a wrapping paper strip which is glued to itself and the coated multifilter segments by means of a glue trace in an overlapping region of the wrapping paper strip.
  • Cutting segments are cut through to cut multisegment filter rods from the multi-segment filter strand formed by applying additional glue to the cutting segments prior to wrapping the multi-segment filter strand with the wrapping paper strip and / or the wrapping paper strips in cutting segment regions of the wrapping paper strip which wrap cutting segments on the wrapped multi-segment filter strand ,
  • the inventive method is based on the basic idea that an additional application of glue leads only to the connection between cutting segments and wrapping strips in the region of the cutting segments, optionally on the cutting segments directly or on the wrapping strip or on both, to a stronger adhesion between cutting segments and wrapping strips, what a later falling out of the cutting segments from the wrapping paper effectively prevented. Since the additional glue application takes place only on the areas of the cutting segments and not on the entire multi-segment filter rod, the additional material costs of glue and the additional contamination of the machine are low.
  • the cutting segment in the wrapping paper is well secured against the stress when cutting multisegment filter bars from the multisegment filter strand. Since now no more cutting segments fall out of the Multisegmentfilterstäben, a high running safety of the machine is guaranteed and there are less downtime of the machine than before.
  • the additional application of glue preferably takes place without contact or in contact.
  • a contactless glue application are the pollution The machine and the cleaning effort is very low, since no glue lugs form on a glue nozzle.
  • a glue application in contact with the segment or the wrapping paper strip also offers a high order security.
  • the additional application of glue preferably takes place with cold glue and / or with hot glue.
  • the additional glue application can be adapted to the requirements of the product and / or the manufacturing process.
  • the additional application of glue is in the form of a point glue application, in the form of several punctiform glue applications and / or in the form of an intermittent glue trace on the cutting segments and / or in the cutting segment regions of the wrapping paper strip, wherein the additional glue application is synchronized in particular to a machine cycle.
  • glue application which are synchronized in particular to the machine cycle, each provide a secure adhesion of the two halves of the cutting segment on the wrapping paper after cutting the cutting segment.
  • the or an additional glue application is preferably carried out on the cutting segments before assembling a multi-segment filter strand or on the multisegment filter strand. This makes it possible, for example, to equip existing machines with additional Thomasbeleimungsvortechniken in places where there is space for this.
  • the or an additional application of glue takes place during a conveying of groups of multifilter segments, in particular on an accelerator drum or a loading wheel.
  • glue takes place during a conveying of groups of multifilter segments, in particular on an accelerator drum or a loading wheel.
  • a glue application is omitted to a position of a missing multifilter segment or a missing or incomplete group of multifilter segments if its incompleteness or absence is determined. This saves glue and prevents contamination of the machine. In particular, in a synchronization to a machine cycle can be determined exactly which Beleimungstakt must be omitted.
