  • Filters for filter cigarettes and other smokable articles in the tobacco processing industry are usually made from a filter tow material which is made of a loose, crimped fiber fabric.
  • a preferred material for the manufacture of cigarette filters is a filter tow made of cellulose acetate threads.
  • the filter tow material is supplied in bales and must be prepared for the production of a filter strand.
  • the lowest possible filter weight with optimal, ie high, pulling resistance is sought. In order to achieve these optimal properties, it is known, for example, according to US Pat. No.
  • the invention has for its object to ensure homogeneous preparation and distribution of the filter material in the filter strand by process-supporting action on the filter tow strip even at high conveying speeds.
  • the filter tow strip is exposed to an air flow flowing in the conveying direction of the filter tow strip at least on a section of the conveying section.
  • conditions which are optimally adapted to the respective treatment stage can be achieved in that the flow speed of the air flow corresponds at least approximately to the conveying speed of the filter tow strip, the flow speed of the air flow preferably being greater than or equal to the conveying speed of the filter tow strip.
  • the effectiveness of the proposed measures can be further increased by the fact that the filter towstrip is accompanied by the air flow on both broad sides, with the additional advantage that fibers detached from the filter towstrip or fibers adhering loosely to it are completely removed.
  • the filter tow strip be acted upon by the air flow during its stretching and also during its gathering.
  • Their property as accompanying the filter tow strip and loose fibers and dust absorbing and discharging air flow is optimized in particular in the aforementioned treatment zones according to a further proposal in that the air flow is generated by an effective suction at the end of a section of the conveyor line.
  • the filter tow strip be subjected to one side in a relaxation zone extending between stretching and spraying by the air flow generated by compressed air supply and suction.
  • the device for carrying out the method mentioned at the outset consists in that the filter tow strip is guided at least on a section of the conveying section formed by the stretching section, the application section and the gathering section through a wind tunnel charged with an air flow guided in the conveying direction of the filter tow section.
  • the effectiveness of the wind tunnel in the sense of a supporting tow guidance is best when the end of a section of the route impacted by the air flow is connected to the suction side of a fan giving the air flow an approximately equal or greater speed relative to the conveying speed of the filter tow strip.
  • An additional increase in effectiveness for guiding and removing detached or loosely adhering fibers from the filter tow strip is provided by the fact that the end of the route section has a suction air connection on both broad sides of the filter tow strip.
  • a process-supporting effect in particularly sensitive treatment phases of the filter tow strip is possible according to further embodiments in that a suction air connection is provided at the outlet of the stretching device and at the outlet of the gathering device.
  • an additional possibility for adjusting the air flow is given in that the wind tunnel is limited by channel walls that can be adjusted transversely to the filter tow strip.
  • the wind tunnel In order to be able to maintain a laminar air flow in particularly critical zones, provision is also made for the wind tunnel to be limited on the outlet side by a flow profile which essentially deflects the suction air flow by 180 °. According to a further development, a stable straight-line design of the filter tow strip after leaving the stretching zone is ensured in that in a relaxation zone extending between the stretching device and the application device, a blowing air nozzle opening into the wind tunnel and a suction air connection connected to the wind tunnel are provided.
  • the advantage achieved by the invention is that especially at high Conveying speeds are increasingly negatively influencing the preparation process Factors such as dynamic pressure or air friction are rendered ineffective.
  • the laminar air flow accompanying the filter tow strip prevents air eddies, so that a trouble-free or homogeneous specific tow treatment in the stretching zone, the relaxation zone and the gathering zone is guaranteed.
  • FIG. 1 is part of a processing arrangement disclosed, for example, in the aforementioned US Pat. No. 5,590,449 for treating a filter tow strip 1 made of cellulose acetate and drawn from a bale in a manner not shown here.
  • a stretching section 3 an application section 4 with a relaxation zone 6 assigned between the stretching section 3 and the application section 4 and a gathering section 7 are provided in succession with respect to the conveying direction (arrow 2).
  • a stretching device forming the stretching section 3 has an input roller pair 8 with motor-driven rollers 9, 11 and an output roller pair 12 with motor-driven rollers 13, 14, the peripheral speeds of which are somewhat greater than the peripheral speed of the rollers 9, 11, so that the elastic filter tow strip 1 is stretched in a defined manner.
  • the pair of rollers 12 is followed by a further pair of rollers 16 made of motor-driven rollers 17, 18, the peripheral speeds of which are lower than those of the rollers 13, 14, so that the filter tow strip 1 relaxes slightly when it is conveyed in accordance with arrow 2.
  • the roller pairs 12 and 16 thus delimit the application section 4, in which an application device 19 in the form of a spraying device 21 is arranged, which from both sides carries the filter tow strip 1 transported in the direction of the arrow 2 with fine droplets of a solvent for the filter tow material, for example triazetin, sprayed.
  • the gathering section 7 is sequential to the application section 4 in which the filter tow strip 1 is conveyed by a motor-driven deflection roller 22 in the direction of arrow 2 and the width of which is constantly reduced by gathering devices, also not shown, which are also disclosed in US Pat. No. 5,590,449.
  • US Pat. No. 5,590,449. In a manner also not shown and disclosed in US Pat. No.
  • the filter tow strip 1 is then introduced into the actual filter rod machine via a stuffing nozzle and an inlet funnel.
  • the filter tow strip 1 is passed through a wind tunnel 23, which extends between the roller pairs 8 and 12 on both sides of the filter tow strip, in which an air flow 24, which runs parallel to the filter tow strip and in its conveying direction (arrow 2), is generated, which approximately has the same or greater speed (for example in the order of 10 m / sec) relative to the conveying speed of the filter tow strip 1 (for example in the order of 600 m / min).
  • the wind tunnel 23 is provided at the end of the stretching section 3 with a suction air connection 26 connected to the suction side of a blower and at the entrance of the stretching section 3 with an air inlet 27.
  • the wind tunnel 23 is delimited by channel walls 28 which can be adjusted transversely to the broad side of the filter tow strip 1.
  • the wind tunnel 23 is provided at the outlet end with a flow profile 29 which deflects the air flow 24 by 180 °. According to FIGS.
  • the filter tow strip 1 is passed in the region of the relaxation zone 6 through a wind tunnel 31, in which it is acted upon on one side by a parallel air flow 32 which flows through a blowing air nozzle 33 opening into the wind tunnel 31 and one with the wind tunnel 31 connected suction air connection 34 is generated.
  • an angled deflector plate 36 and a guide plate 37 are provided on the upper side at the inlet of the wind tunnel 31.
  • the filter tow strip 1 is likewise passed through a wind tunnel 38, in which it is acted upon on both sides by a parallel air flow 39 which is generated by a suction air connection 41 and air inlet 40 connected to the suction side of a blower.
