In the following figures, the same or similar elements or corresponding parts are provided with the same reference numerals, so that apart from a respective renewed idea.

According to Fig. 1 the processing device for a stripped off a bale strip 2 of filter tow, eg cellulose acetate, with continuous fibers following main assemblies that passes through the strip 2 below, on: a withdrawal line 3, a Vorreckstrecke 4, a stretch 6, a Auftragsstrecke 7, a Raffstrecke 8 and a feed path 9. The feed line 9 is used to supply a strip portion to an inlet device of a filter rod machine 11 shown schematically, for example, known from the tobacco processing industry type KDF2, KDF3 or KDF4 the patent applicant.

The withdrawal line 3, in which the withdrawn from a bale not shown here filter material strip 2 is conveyed, has a spreader nozzle 16, which receives compressed air from a compressed air source. The compressed air is used to spread the extracted filter fabric in this section. A controllable spreader nozzle is eg in the US-A-4,259,769 described.

Via a deflection plate 19 of the filter tow 2 passes into the pre-stretch 4, on the one hand by a pair of rollers 21 with the rollers 22, 23, on the other hand by a pair of rollers 24 with motor-driven rollers 26, 27 is limited. The rollers 22, 23 are towed from the tow strip, i. they run empty with more or less resistance. If necessary, they can be powered by a motor. They can also be pressed in a manner known per se with controllable force against each other. In the Vorreckstrecke 4, in which the strip portion is conveyed obliquely down, the filter tow 2 is vorgereckt.

To the pair of rollers 24, the stretching line 6 connects, in which the filter tow 2 is conveyed vertically or with a vertical component from top to bottom. At the end of the stretching section 6 is another pair of rollers 39 of motor-driven rollers 41, 42 whose peripheral speeds are slightly greater than the peripheral speeds of the rollers 26, 27, so that the elastic filter tow 2 is defined stretched. The roller pairs 24 and 39 thus form the actual stretching device. The rollers 26 and 41 have a rigid, grooved surface, each contacting a compliant surface of the rollers 27 and 42, respectively. Such roll configurations are known from the aforementioned filter tup processing devices AF 2, AF 3 and AF 4 of the applicant and, for example, in US-A-3,317,965 and US-A-3 255 506 described.

The roller pair 39 is followed by a further pair of rollers 43 whose peripheral speeds are lower than those of the rollers 41, 42, so that the filter tow 2 is slightly relaxed in its promotion. The pair of rollers 43 has a smooth rubber roller 44, which is in contact with the steel roller 46. The roller pairs 39 and 43 thus limit the application path 7, which in the present case is arranged approximately horizontally, in which an applicator 47 is arranged, for example in the form of a spraying device or spray nozzle.

The applicator 47 sprays the transported filter tow 2 from one or both sides with fine droplets of solvent for the filter tow material, e.g. Triacetin.

The applicator 47 is preceded by a spreader nozzle 18, so that the stretched filter tow 2 is spread and the solvent wets a larger surface of the filter tow 2. This spreader nozzle 18 as well as the spreader nozzles 16, 17 upstream of the roller pair 21 of the pre-stretching section 4 are subjected to compressed air.

The order path 7 is a shirring 8 downstream, in which the filter tow 2 is conveyed with predominantly vertical component of a motor-driven roller 53 from bottom to top.

The roller 53 is arranged downstream of a feed path 9. In the feed line 9 also known per se so-called. Stopfdüse is present. After passing through the Stopfdüse the filter tow is fed to a filter rod machine 11.

For more details is expressly on US-A-5 590 449 directed.

Fig. 2 shows schematically in a plan view from above an applicator 47 with a housing 50 through which the strip 2 is conveyed from right to left through the applicator 47 therethrough. In the applicator 47, the strip 2 is provided with triacetin as a liquid additive, wherein on the outlet side of the applicator 47 in consequence of the promotion of the filter material strip 2 with triacetin impregnated lint from the applicator 47 are entrained.

In the exit region of the strip 2 from the housing 50, two intake manifolds 61, 62 are arranged on both sides of the filter material strip 2, which are provided with negative pressure by a ventilator (cf. Fig. 4a , Reference numeral 81) are acted upon. Here, by means of the intake manifold 61, 62 which are arranged aligned on the exit side of the strip 2 at the output from the housing 50, sucked at the exit or at the exit slit of the housing 50 for the strip 2 accumulated triacetin lint or removed.

Fig. 3 schematically shows a front view in cross-section on the application device 47 on the outlet side of the filter material strip 2. The intake manifold 61, 62 have on their suction suction openings 63, 64, the surface normal parallel to Conveying plane of the filter material strip 2 is.

How out Fig. 3 As can be seen, the conveying plane of the filter material strip 2 is perpendicular to the plane of the drawing. The intake ports 61, 62 are arranged at a distance from each other which is wider than the filter material strip 2 provided with triacetin.

As in FIGS. 2 and 3 indicated, the lateral positions of the intake manifold 61, 62, as indicated by corresponding arrows, adjustable. The intake ports 61, 62 are arranged directly in the region of the outlet of the filter material strip 2 from the housing 50, so that the strip 2 entrained and exiting the housing 50 fluff and particles immediately outside the housing 50 by the voltage applied to the intake manifold 61, 62 negative pressure be sucked or removed from the environment of the strip 2.

In Fig. 3 are schematically the lint, which are impregnated with triacetin, designated by the reference numeral 65. The fluff 65 are on the side inclined obliquely downward and straight, that is not curved, intake manifold 61, 62 in a Flusenabscheidekammer (see. Fig. 4a, 4b , Reference numeral 72) sucked.

Characterized in that the intake manifold 61, 62 are arranged on both sides of the emerging from the applicator 47 filter material strip 2, a symmetrical suction of the lint 65 is achieved from the vicinity of the filter material strip 2, in particular triacetin-containing lint 65, located on the (here not shown) leaking gap for the strip 2 on the housing 50 accumulate on the intake manifold 61, 62 are removed. In particular, the conveying paths of the suction air from the inlet or from the inlet side of the two intake manifolds 61, 62 and of the Suction openings 63, 64 through a Flusenabscheidekammer 72 (see. Fig. 4a, 4b , Reference numeral 72) until entering a (first) Triacetinabscheidekammer (see. Fig. 4a, 4b , Reference numeral 75) is the same. Here, 62 negative pressure from a vacuum source is applied to both intake manifolds 61, 62.

In Fig. 4a and 4b in each case a schematic arrangement for the separation of lint and triacetin is shown, with the illustration of the intake manifold was omitted for reasons of clarity. The arrangement in Fig. 4a or 4b has a channel space 71 on which the intake manifold 61, 62, in particular slidably disposed. Here, the channel space 71 is disposed below the filter material strip 2 (see. Fig. 3 ). The channel space 71 is at the top of a lid 69 (see. Fig. 2, 3rd ), on which the intake manifold 61, 62 are arranged. In the FIGS. 4a, 4b was apart from the representation of the lid 69 and the intake manifold 61, 62 accordingly.

The channel space 71 has inside a Flusenabscheidekammer 72, in which the sucked lint via the intake manifold 61, 62 reach. In the deposition chamber 72, the lint soaked with triacetin or not soaked are separated, wherein the ambient air freed from the lint or particles is supplied to a first liquid separation chamber 75 by applying a negative pressure.

In this case, the channel space 71 in the interior has a partition wall 73, which has an opening 74, so that the liberated from lint surrounding air from the Flusenabscheidekammer 72 passes through the aperture 74 and enters the Flüssigkeitsabscheidekammer 75. The channel space 71 may be formed as a kind of drawer in one or the channel 76, so that the channel space 71 in the channel 76, which surrounds the channel space 71 disposed therein partially or completely, is inserted or is introduced. In this case, an upper-side channel wall of the channel 76 then forms the cover 69 (cf. Fig. 2, 3rd ), on which the intake ports 61, 62 are arranged.

Here, a negative pressure of a suction-side vacuum source, as shown schematically in FIG Fig. 4a is indicated by a fan 81, applied via the channel 76 and the channel space 71 to the intake ports 61, 62, so that lint and particles are sucked into the channel space 71.

In the liquid separation chamber 75, in a first step, triacetin is separated from the ambient air which has been lint-free. Subsequently, the ambient air is conducted via a channel 76 to a second Triacetin deposition device or chamber 77, which is formed with a wire mesh or demister 78. By the demister 78 triacetin is separated from the ambient air a second time, wherein the liquid separation device 77 is connected to the suction side of the fan 81.

In Fig. 4a It is shown that the Flüssigkeitsabscheidevorrichtung 77 is vertically flowed through by the sucked ambient air, while according to the in Fig. 4b illustrated embodiment, the Flüssigkeitsabscheidevorrichtung 77 is arranged obliquely with a predetermined inclination to the vertical, so that the deposited triacetin collects on the wall of the Flüssigkeitsabscheidevorrichtung 77 and runs down.

According to the in Fig. 4a and 4b illustrated embodiment, a multi-stage deposition, wherein initially a deposition of solids in the form of lint or with triacetin impregnated lint and then carried out a two-stage liquid separation. The solids separation or the lint deposition takes place by a reduction in the flow velocity, wherein the air flows in the air separation device or in the air separation chamber 72 are additionally deflected by a corresponding flow guide. The separation of triacetin from the intake ambient air can be done by deflection separation or inertial separation with Abscheideprofilen, for example, in the first Flüssigkeitsabscheidekammer 75. The recovered from the ambient air triacetin or deposited triacetin is then returned to a corresponding reserve tank for triacetin.

In Fig. 5 is schematically a section of a device or arrangement for processing a filter tow 2 with an applicator 47 shown in the cutout. The filter tow 2 is thereby conveyed through the stretch 6 to the order path 7.

In or on the Auftragsstrecke 6 suction means 91, 92 are arranged to suck air, preferably in the region of the pairs of rollers of the stretching section 6, being removed by the suction means 91, 92 loose, dry tow fibers. Here, the air or ambient air, which is sucked in by the suction devices 91, 92, permanently removed via discharge lines 94 from the vicinity of the stretching section 6 and the entire processing device.

After passing through the stretching section 6 of the filter tow 2 is passed through the order path 7 with the applicator 47, wherein at the outlet of the applicator 47 by means of a schematically designated suction 85 triacetinhaltige Lint can be sucked, so that flying around triacetin fluff are removed from the conveying area of the filter tempest 2.

The suction device 85 is connected via a connecting line 87 on the suction side with a blower 86. In particular, the suction device 85 has a Flusenabscheidekammer to secrete fluff from the intake ambient air from the outlet end of the applicator 47, so that after passing through the Flusenabscheidekammer (see. Fig. 4a, 4b Reference numeral 72) is sucked from the fan 86 liberated ambient air from the fan.

In addition, in one embodiment, in the connecting line 87 between the suction device 85 and the blower 86, a Flüssigkeitsabscheidekammer (see. Fig. 4a, 4b Reference numeral 75) may be provided to separate triacetin as a liquid from the ambient air liberated from triacetin and lint.

The extracted by means of the blower 86 at the outlet end of the filter tow 2 on the applicator 47 ambient air is freed from lint and possibly emaciated by triacetin or a liquid. By means of the blower 86, the liberated from lint and optionally trimmed to triacetin ambient air via a supply line 88 to an outlet opening 89 in the environment 90 of the device for processing the filter tow 2. In this case, in the environment 90 of the device or the treatment device, the normal atmospheric pressure prevails.

In addition, the air sucked by the blower 86 at the outlet side of the applicator 47 and recirculated ambient air, which liberated from lint and possibly emaciated by a liquid is, fresh air from a fresh air source, for example in the form of a fan 95, in particular axial fan mixed. In this case, fresh air is sucked in by a fan 95 and discharged into the supply line 88 for the liberated from fluff ambient air, so that at the outlet opening 89 fresh air and the recirculated ambient air from the environment of the applicator is discharged into the atmosphere of the environment 90.

All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention.
