  • the stretching section which advantageously comprises at least two pairs of stretching rolls with different peripheral speeds, can have a length of 800 mm to 1200 mm, preferably 1000 mm. It has surprisingly been found that such a length gives optimal values with regard to the tow yield (tow amount per unit length with constant tensile resistance in the finished filter rod).
  • the width of the filter strip in the stretching section and the application section can preferably be 120 mm to 150 mm. With such a small width, two or more filter tow strips simultaneously drawn off from bales and guided in parallel can be prepared relatively easily, for which purpose the same processing devices can predominantly be used. If the filter strand machine is then designed to process two filter tow strips simultaneously to encased filter strands (so-called two-strand machine), the production performance of a treatment plant can be increased significantly without major additional mechanical expenditure.
  • the stretching section at least approximately vertically or with a predominant be arranged with a vertical component preferred promotion of the strip from top to bottom.
  • the Application device can preferably be at least approximately horizontally arranged order line and than the filter tow after relaxing against the Stretching with finely divided liquid such as triazetin for Dissolve the filter tow fibers by spraying from both sides Spray device can be formed.

  • the actual stretching section can be preceded by a pre-stretching section, the conveying direction of the filter tow strip, which preferably runs from top to bottom, can have a vertical and a horizontal component.
  • a conditioning device for conditioning the filter tow strip to a constant relative humidity preferably a drying device, can be arranged in an advantageous, independent inventive rank of the invention.
  • B. can be designed as an infrared heater.
  • the beginning of the stretching section can be a preferably non-drivable pair of rolls, the rolls of which can be pressed together with controllable force, while at the end of the stretching section the first pair of rolls of the actual stretching section can be arranged.
  • the direction of the filter tow strip reversing roller pairs of stretching and application section can each z.
  • a pneumatic spreading nozzle can be arranged upstream of the stretching section, from which blown air emerges for spreading the filter tow fibers.
  • the application device can be provided with a charging device for applying electrostatic charges to the filter tow strip. This improves the separation of the fibers of the filter tow strip and makes spraying more uniform, especially when the droplets of the dissolving liquid receive charges with opposite polarity to the charges on the filter tow strip.
  • the application device can advantageously be followed by a discharge device designed as an ionization device.
  • the above-mentioned conditioning device preferably in the form of a drying device, can be controlled by a control arrangement in order to achieve a constant relative humidity in the filter tow strip, to which a measurement signal can be fed from a moisture measurement device.

  • the spraying device 48 can be designed as described in US Pat. No.
  • the width of the filter tow strip in the stretching section 6 and the application section 7 is preferably between 120 mm and 150 mm. This is such a small width that it allows processing devices for two filter tow strips guided in parallel to be arranged one behind the other perpendicular to the plane of the drawing and thus to be used twice. The strips can then be processed into filter rods in a filter strand machine that processes two strands simultaneously.
  • the gathering section 8 Downstream of the application section is the gathering section 8, in which section 2e of the filter tow strip is conveyed vertically or with a predominantly vertical component (as shown) by a pair of rolls 51 with motor-driven rolls 52, 53 from bottom to top in the direction of arrow 54.
