Definitions

  • the invention relates to a device for preparing at least one Fiber strands of a tobacco processing industry strand machine for further processing in the strand machine, provided for each fiber strand is: a strand conveyor in a strand guide channel for conveying the fiber strand, a trimmer for removing excess fibers from the Fiber strand.
  • a strand of fibers can be, for example, a strand of tobacco fibers act.
  • a rod machine of the tobacco processing industry it can be for example, a double-strand machine for the production of cigarettes or double filter cigarettes act.
  • DE 4333046 A1 of the applicant, US 5,526,826 of Applicant corresponds to a device of the type described above.
  • a repellent for removing the excess tobacco fibers here is one rotating body serving as a deflector surface provided which one on its side facing the trim discs Carries circular knife.
  • the object of the present invention is to improve such devices.
  • Such a section-wise reinforcement is used in the production of Tobacco fiber cigarettes, also known as head reinforcement, in the prior art Technology is known for example from DE 3837201 A1, which is US Pat. No. 4,883,076 corresponds; in these known devices for head reinforcement, two in a plane with the tobacco rod arranged clamping discs used as Trim disks to take excess of the tobacco rod and on their Have pockets in which a certain excess on the The tobacco rod remains standing, so that it later closes when the rod is compacted leads to a more compacted area. Practice these pockets in the trim discs however, additional forces are exerted on the tobacco rod, leading to a spread of weight lead cigarettes manufactured in this way.
  • the inventive design of the device for Preparing a strand of fiber improves the quality of the head reinforcement. Because Due to the moving side walls, the head reinforcement is in the fiber strand introduced without relative movement between head reinforcement and fiber strand. The head reinforcement can therefore be introduced much more regularly and precisely.
  • the moving side wall as at least one circumferential belt, preferably designed as a toothed belt.
  • a toothed belt can be easily driven using toothed pulleys.
  • only one or both side walls of the strand guide channel with the fiber strand and have only one or both side walls have the recesses for introducing the head reinforcements on.
  • a Control unit synchronize the running speed of the side walls to each other, in which the control unit the speed of drive rollers for the side walls controls.
  • This can advantageously achieve that the intended Recesses in both side walls always at the same level with the Run along the fiber strand.
  • the repellent is formed as a substantially frustoconical body of revolution
  • the axis of rotation preferably runs perpendicular to the direction of movement of the strand and preferably parallel to the axes of rotation of the trim discs.
  • the outer surface of the rotating body with that of the trim discs adjacent end face of the rotating body an acute angle between 5 ° and forms about 40 °, which angle at least on parts of the lateral surface increasing distance of the lateral surface from the end face or the trim discs increases. It is particularly advantageous if the angle increases steadily by one to ensure fluid repellency of the fibers. It is even more preferred if the angle increases up to 90 ° and, if necessary, beyond it at an obtuse angle of passes up to 120 °. This has also proven to be advantageous for gentle distraction of the tobacco fibers removed.
  • the device can also be used to prepare two parallel fiber strands, For example, in a strand machine designed as a double strand machine.
  • the fiber strands are each from a strand conveyor in a strand guide channel promoted and each by a trimmer for further processing in prepared the double strand machine.
  • the diameter each of the trim discs adjacent to the parallel strand the distance of the Fiber strands is adjusted.
  • the diameter of this Trim discs roughly corresponds to the distance between the fiber strands. On this can also be the case with the narrow spaces prevailing in double-strand machines
