- the fiber length used Fibers is smaller than the length of the filter to be manufactured or Filter element.
- the length of the fibers should therefore be between 0.1 mm and 30 mm and in particular between 0.2 mm and 10 mm. at the length of the filter to be manufactured is one usual filter for a cigarette or a filter segment Multi-segment filters of cigarettes. If also the middle one Fiber diameter in the range of 10 to 40 microns, especially 20 to 38 microns and is particularly preferably between 30 and 35 microns, is very homogeneous filter can be produced.
- the curing device 39 can be a microwave heater, a Include laser heating, hot plates or sliding contacts. By Heating the binding components, for example the outer layer of Bicomponent fibers or latex combine the individual fibers in the Fiber strand with each other and merge superficially.
- the Hardening device 39 can also dry out liquid Allow form added binding components. At the When the fiber strand cools, the melted ones harden Areas of the heated binding components again. The The resulting lattice structure gives the fiber strand stability and hardness.
- the hardened fiber filter strand 38 becomes filter rods 40 cut.
- the curing of the filter is also after Cutting into the filter rods 40 possible.

- In the separating chamber 45 are sieve drums 21, which are in the direction of the arrow rotate.
- the Spiked rollers 26 also serve in this case, but not yet isolated fiber material or the related To break fiber groups into individual fibers so that the isolated fibers through the outlet openings of the screen drum 21 in can reach the funnel 53. Through the appropriate Air flows and in this case also gravity, then reach the individual fibers 27 in the area of the suction belt conveyor 32, the is designed in this case with suction belt cheeks 57.
- the compacted fiber strand 34 is then by means of an air flow 37 through the nozzle 36 of the Suction belt 43 'detached and transferred to a format 56.
- the compressed fiber strand 34 reaches one as usual Wrapping material strip 42, which is conveyed on a format belt becomes.
- the remaining process steps correspond to those according to the Figures 2 to 4.
- FIG. 8 shows part of a device according to the invention in one shown schematic view.

- the of the fiber strand 33 conveyed to the suction belt 43 enters the Effective area of a nozzle 68, the compressed air 69 on the fiber strand in Area of the deflection roller 65 and thereby the fiber strand 33 detaches from the suction belt 43.
- the angle of the nozzle or compressed air, that acts on the fiber strand 33 is adjustable.
- After removing the Fiber strand 33 from the suction belt 43 reaches the ring nozzle 70.
- the air 67 flowing through the nozzle slot 71 may vary Nozzle design perform various functions.
- the function is always such that the nozzle 70 in the nozzle inlet channel prevailing negative pressure the fiber strand 33 from that on the Deflection roller 65, which can also be designed as a pressure plate 65, detaching running suction belt 43.
- the fiber strand can pass through Flow of compressed air 67 onto the fiber strand under certain Angles conveying the fiber strand in the first format-forming Allow hollow cone 72.
- the Compressed air 67 dissolves the strand into individual fibers or fiber groups and so the individual fibers or fiber groups in the first format-forming Hollow cone 72 promotes.
- the fiber strand or the individual fibers and fiber groups in the first format-forming Hollow cone 72 and then into the second format-forming hollow cone 73 promoted.
- the second format-forming hollow cone 73 has a smaller taper than that first hollow cone 72. Located in the first format-forming hollow cone 72 vent holes. These ventilation holes ensure that Air separation of the nozzle air 69 and 67.
- the fiber strand 33 as a fiber strand is transferred, this is in the format-forming hollow cones 72 and 73 shaped from above and from the one running in format Format tape 58 from below.
- the complete delivery of the Fiber strand 33 on the format tape or Wrapping material strips 42 takes place under the hollow cone 73 second variant, in which single fibers and fiber groups of the Nozzle air 69 are pressed into the format-forming hollow cone, there is a jam due to the tapering of the hollow cone Individual fibers and fiber groups, so that there is a new fiber strand forms.
- the strand is completely formed in the second hollow cone 73 and at the end of the second hollow cone 73 to the format tape or Hand over wrapping material strips 42. Then the Wrapping material strips 42 wrapped around the strand and as usual closed so as to form the fiber filter strand 38.
- the fiber materials can be cellulose fibers thermoplastic starch, flax fibers, hemp fibers, flax fibers, Sheep wool fibers, cotton fibers or multi-component fibers, especially bicomponent fibers act that length have that is smaller than the filter to be produced and a thickness have, for example, in the range of 25 and 30 microns.
