  • the invention further relates to a method for producing a strand of the tobacco-processing industry, in particular a filter or a tobacco rod.
  • the apparatus for producing a tobacco rod for the production of a cigarette rod has a rotating strand conveyor, which passes through a strand construction zone, wherein the strand conveyor in the Strand building zone for strand formation with fibers is chargeable.
  • the strand conveyor has a discharge end for discharging the fiber strand.
  • the strand conveyor is assigned an excess removal device.
  • means are provided for producing a cross-sectional contour of the fiber strand corresponding at least along a peripheral section of the fiber strand of at least part of the strand contour of the finished strand.
  • the tobacco band used there is guided in a tobacco channel and assigned to the rear of a vacuum chamber which is connected to a vacuum source and causes a suction through an air-permeable channel bottom and through the air-permeable tobacco band.
  • tobacco fibers are aufauert on the tobacco band and held by the induced draft on the tobacco band.
  • the tobacco band has a cross-sectional contour which corresponds at least approximately to a section of the cross-sectional contour of a cigarette rod produced.
  • a format device which has an inlet finger, which is adapted to the cross-sectional contour of the tobacco band and ensures that the preformed tobacco rod is introduced into the subsequent format.
  • this device has the disadvantage that the manufacturing accuracy of the curved in the cross-sectional contour inlet finger must be extremely high.
  • only a relatively short service life is possible because a relatively high wear of the format strip and the inlet finger in the separation area or effective range of the inlet finger with the format tape can not be avoided.
  • Object of the present invention is to provide a Saugstrangier and a method for producing a fiber strand of the tobacco-processing industry, by means of which are made possible in a preformed by a Saugstrang employer fiber strand long service life.
  • the straight cross-sectional contour is preferred, the production of the inlet finger is much easier and possible are the problems of the prior art with the in the cross-sectional contour curved inlet fingers, in particular a curved leading edge of the inlet finger, not given anymore. As a result, less wear occurs in the effective region of the inlet finger on the conveyor belt, so that longer service lives can be achieved.
  • the lower curvature is to be understood in the context of the invention in comparison to the curvature in Faseraufschauer Scheme the fiber channel.
  • the cross-sectional contour of the conveyor belt is curved transversely to the conveying direction of the conveyor belt or straight.

  • the second region is a region of the fiber waking region, for example at least two-thirds of the fiber waving region, with two-thirds of the fiber waving region comprising the downstream part of the fiber waving region.
  • the curvature forms a partial circle or a partial ellipse. In this case, it is possible to impose on the fiber strand a type of preforming which may result in cylindrically round or elliptical cigarettes or filter strands.
  • the Saugstrang adapter acts in the separation region of the fiber strand with an inlet finger of a format device, such that the inlet finger separates a strand formed on the conveyor belt from the conveyor belt, wherein the inlet finger is formed in the separation region transversely to the conveying direction of the Saugstrangdeciers at least partially straight.
  • the detachment takes place here by a cooperation of the centrifugal force and the inertia of the fibers with a shutdown or termination of the application of negative pressure and a channeling or forwarding of the fibers through the inlet finger.
  • the inlet finger then has a straight edge, which lies on the side of the inlet finger upstream of the conveying direction of the conveyor belt and is preferably arranged substantially perpendicular to the conveying direction and substantially parallel to the cross-sectional contour of the conveyor belt at this point.
  • the edge of the inlet finger or the inlet finger transversely to the conveying direction of the conveyor belt is at least as wide as the conveyor belt, so that all adhering to the conveyor belt fibers can be efficiently detached.
  • a rod making machine of the tobacco-processing industry is provided with an above-described suction-strand conveyor according to the invention or described as preferred or a combination according to the invention which has been described above.
  • strands of the tobacco-processing industry in particular filter or tobacco strands, can be produced efficiently and with long service life.

  • the lower run 2a of the suction belt 2 is guided in a fiber channel 6 partially with corresponding to the desired contour of the finished strand curved air-permeable bottom.
  • the fiber channel 6 is rectilinear in a guide body 8.
  • the guide body 8 is in section in the FIGS. 2a to 2d shown schematically.
  • the guide body 8 may be integrally but preferably in several pieces, for example according to the EP 1 281 329 A2 .
  • Sequences or individual elements have a surface to the suction belt or the fiber channel, which may have a corresponding desired shape to which the suction belt conforms, so that a cross-sectional contour of the suction belt according to the invention results, which substantially corresponds to the contour of the surface of the guide body 8 ,
  • the guided in the fiber channel 6 suction belt 2 is the rear side associated with a vacuum chamber 9, which is connected to a vacuum source 11 and through the air-permeable channel bottom and through the air-permeable suction belt 2 causes a suction.
  • the suction belt 2 runs in the direction of the arrow 12.
  • the mouth of a conveyor shaft 13 for conveying fibers or a mixture of fibers and other constituents of a tobacco or filter strand through which loose or scattered fibers are fed from a distributor, not shown, in the direction of the arrows 14 to the suction belt 2 defines a strand construction zone Z, in which the fiber strand 16 is aufauert to its full height.
  • the production well 13 may be the end of a fluid bed conveyor.
  • the bottom of the fiber channel 6 is partially curved in a U-shape, namely in particular in the area of the strand construction zone Z, so that the lower strand 2a of the suction belt 2 assumes the desired contour of the finished filter strand.
  • the negative pressure chamber 9 extends over almost the entire length of the fiber channel 6 and is assigned to at least a portion of the suction belt 2 transversely to the conveying direction of the suction belt 2.
  • the vacuum chamber 9 is not quite as far as the suction belt 2 is wide.
