  • Fig. 1 a front view of a filter attachment type MAX of the applicant is shown schematically. This machine has the following details:
  • An inlet drum 1 transfers the cigarettes produced on a cigarette manufacturing machine to two staggering drums 2, which decaffeinate the staggered cigarettes and deliver them in rows of two each with a gap between the cigarettes to a compilation drum 3.
  • the filter rods pass from a magazine 4 to a cutting drum 6 where they are cut into filter plugs twice the length of use, staggered on a staggering drum 7, aligned by a sliding drum 8 to a series of consecutive plugs and an accelerator drum 9 in the spaces between the rows of cigarettes on the assembly drum 3 filed.

  • a covering paper strip 12 drawn off from a tipping paper bobbin 13 is glued by a gluing device 14 and then cut in a cutting device 16 on a cutting drum 17, which is designed, for example, as a suction drum, by the knives of a knife drum 18 in covering laminae.
  • the separated pad sheets are adhered to the cigarette filter-cigarette groups on the transfer drum 11 and rolled on a roller drum 19 around the cigarette filter groups.
  • the finished double-filter cigarettes are fed via a drying drum 21 of a cutting drum 22 and assembled on this by central cutting through the filter plug through to single-filter cigarettes.
  • a turning device 23 applies a series of filter cigarettes and simultaneously transfers them to the continuous one inverted filter cigarette series.
  • Via a test drum 24, the filter cigarettes reach an ejection drum 26.
  • a discharge drum 28 cooperating with a brake drum 27 places the filter cigarettes on a depositing belt 29.
  • the pad cutting device 16 is described in DE 39 18 137 C2 closer. In order to further process the cut pads, it is necessary that two consecutive pads have a gap. This is achieved in that the peripheral speed of the cutting drum 17 is greater than the mean web speed of the lining strip 12.
  • the oscillator assembly 33 is provided. It is arranged on a support plate pivotable about an axis and pivotable by means of a drive 48, so that the tipping paper strip 12 can be lifted off the glue application roller 20 during interruptions in operation.
  • a pivot drive 48 a pneumatic or hydraulic cylinder is provided in the illustrated case.
  • the exact function of the oscillator arrangement 33 can also be taken from DE 39 18 137 C2.
  • the transport device according to the invention is shown schematically in an embodiment in FIG.
  • the tipping paper strip 12 is removed from the tipping paper stack 13 by means of a first draw roller device 30. This is followed by after three deflections Beleimvorraum 14 with the glue applicator roll 20, the oscillator device or deflection and oscillator assembly 33 and the cutting drum 17, wherein the cutting drum 17 may be formed as a suction roll.
  • the conveying direction 10 of the tipping paper strip 12 is also shown in FIG. 1.
  • the tension of the tipping paper strip 12 is measured on the measuring roller 36.
  • the measurement result is fed to the control device 25, which regulates the negative pressure in the cutting drum 17 or the rotational speed of the cutting drum 17 or the suction drum or roller 17 in order to achieve a constant tension in this case on the average.
  • it can only be a constant maintenance of the average value of the tensile stress, since the oscillator device 33 causes a variation of the tensile stress from a minimum value to a maximum value in each revolution.
  • this short-term variation is desired because of the above-mentioned desire to produce a clean cut and further to allow the cut fillet sheets to follow one another.
  • the tension would be controlled directly and not necessarily the mean value of the tension.
  • the tensile stress which prevails after the first draw roller device 30 is generated essentially by the cutting drum 17 or suction drum or drum 17.
  • the applied vacuum or vacuum suction roller 17 rotates at an overspeed and thus generates a slip of the lining paper 12.
  • the tension depends essentially on the coefficient of friction between the tipping paper 12 and the suction roll 17 and the pressure prevailing in the suction roll 17 vacuum.
  • the transport device according to the invention may be part of a filter attachment machine like that of FIG. 1.
  • the tipping paper strip 12 is withdrawn from a reel, not shown, by means of the first draw roller device 30.

  • the tipping paper strip 12 is guided via a heater 39, at the downstream of which a guide 41 connects and then the suction roll 31.
  • a knife drum 32 which engages with the suction roll 31.
  • the suction roll 31 is cleaned by means of a cleaning brush 42.
  • the regulation of the paper tension is done by controlling the pressure prevailing in the suction roller 31 negative pressure.
  • a vacuum pump 44 is provided, which is connected via a line 46 with a bore 52 of a control body 51 of the suction roller 31. In the region of this bore 52, the suction force is exerted on the tipping paper strip 12 and thus provided the tipping paper strip corresponding to a tensile stress.
  • the negative pressure in the line 46 and the bore 52 is regulated by means of a proportional valve 45, which is arranged in a bypass line 47 and whose opening is controlled via the measuring roller 36.
  • the regulation is indicated by the dashed line.
  • a further vacuum pump 43 is also provided, which generates a corresponding negative pressure in a line 46 'and thus in the bore 53.
  • This is a holding vacuum for holding and transporting the already cut covering sheets.
  • Another switchable auxiliary vacuum which can prevail in the bore 54, serves to remove not glued leaflets for suction. The connection of this is done with a mechanical slide, which is pneumatically actuated.
  • at least one should separate vacuum pump 44 may be provided for the negative pressure in the region of the bore 52.
  • the invention serves in particular to minimize variations in the tension of tipping paper strips, which can be caused due to varying parameters of the tipping paper strip as different coefficients of friction, different air permeability, different water absorbency and thus elongation of the tipping paper, or by parameters of the suction rollers 31 and the cutting drum 17 as the hole pattern, the surface texture, in particular the friction coefficient, the degree of contamination and the height and the constancy of the vacuum. Since the paper manufacturers obtain the base papers from different sources, they can show very different behavior even with the same designations of the paper. This can lead to corresponding transport devices without corresponding regulation to very different tensile forces or tensile stresses.
  • the tensile stresses can also change due to the surface texture of the suction roll or the cutting drum due to contamination with, for example, glue.
  • the holes of the roller or drums can be clogged by glue deposition and the size or height of the vacuum can fluctuate especially at a central vacuum supply. Due to the change in paper tension, variations in the degree of filter ventilation, slipped padding, tearing paper cracks due to the oscillator, and tucking of the tipping paper strip between rotating pinch rollers can result in corresponding downtime.
  • the adjustment of the setpoint of the paper tension can be made either by a switch or keys or numerically on a machine control unit.
