Definitions
- the present invention relates to a filter tow strip having the features of the preamble of claim 1, a filter rod machine, a method for producing a filter tow strip and a method for producing filter rods.
- a filter tow strip of the type mentioned is for example from the EP 0 629 722 A1 known to the applicant.
- filters are used, which are made of a band or a continuous strand of crimped cellulose acetate fibers, the so-called filter tow.
- spun filaments of cellulose acetate are crimped in a stuffer box, whereby the impressed crimp structure is fixed while passing through a dryer.
- the filter tow After the filter tow has been brought to a constant final moisture content, it is loosely placed in jugs several meters high in regular patterns. The loose tow layer is then compacted in bale presses into a filter tow bale and finally packed, which is provided for further processing into filters.
- filter tow to filter rods The processing of filter tow to filter rods is carried out on a filter rod machine on which the filter tow in a processing section as strong as possible to develop its maximum filling power, which is then gathered on the format of the future cigarette filter and coated with paper.
- a filter rod machine On which the filter tow in a processing section as strong as possible to develop its maximum filling power, which is then gathered on the format of the future cigarette filter and coated with paper.
- To buckle the filter tow it is pulled apart by means of compressed air driven spreader nozzles and stretched by a system of draw rolls with threaded or screwed surfaces. Thereafter, the spread filter tow is fed to a triacetin spray box, in which the acetate surface is dissolved and tackified.
- the filter tow band In the format part of the filter rod machine, the filter tow band is gathered and compressed to the cross section of the future filter rod. During this process, the filaments stick together and form a three-dimensional spatial network structure with the
- the invention has for its object to provide a filter tow strip, in particular Twin Tow made of crosslinked and crimped filaments, which allows a problem-free processing on a filter rod machine, especially on a double filter rod machine, the separation of the filter tow strip for continuous production as evenly as possible should be done.
- the invention is further based on the object of specifying a filter rod machine, in particular a double filter rod machine, with which the filter tow strip can be separated as resistant as possible, and a method for producing a filter tow strip, in particular a twin tow and a method for producing filter rods.
- this object is achieved with regard to the filter tow strip by the subject-matter of claim 1, with regard to the filter rod machine by the subject-matter of claim 7 and with regard to the methods by the subject-matter of claim 12 and the subject-matter of claim 18.
- the invention has the advantage that the separation of the filter tow strip according to the invention is achieved largely without problems even in fast-running processes. Due to the uniform binding force of the Filter Tow halves along the Twin Tows, voltage fluctuations and thus quality fluctuations of the filter rods are effectively avoided.
- the filter tow strip according to the invention is defined by the maximum transverse cutting force, which does not exceed 20 cN, and over a length of 20 cm. This has the advantage that the release properties of the strip can be set much more accurately than in the strip according to FIG EP 0 629 722 A1 so that the separation behavior of the strip is improved.
- the division of the filter tow strip into two individual filter tow strips in front of the spreader nozzle or in front of the spreader nozzles of the filter rod machine according to the invention makes it possible, without difficulty - depending on the existing filter tow material - between a twin tow bale, i. a bale with a filter tow according to the invention, and, if necessary, two bales with standard filter tow to change.

- the filaments 13, which connect the two partial strips 12a, 12b in the region of lower crosslinking density 11, are mutually looped and / or hooked in such a way that the connecting filaments 13 form crossing points 14.
- the invention is not limited to filter tow strip 10 with two partial strips, but generally includes multi-width filter tow strip with a plurality of partial strips, for example. Three or four partial strips, which are respectively connected to each other.
- the filter tow strip 10 according to Fig. 1 is clamped between two jaws A of a measuring device, which are moved apart so far that the two sub-strips 12a, 12b of the filter tow strip or the Twin Tows and the intermediate connection region 11 can be seen with low crosslinking density.
- the jaws A comb clamps can be used, in particular for measurement in superimposed partial strips.
- connection region 11 is designed such that the maximum transverse separation force required to separate the partial strips does not exceed 20 cN over a length of approximately 20 cm.
- the maximum transverse separation force corresponds to that force perpendicular to the longitudinal extension of the filter tow strip 10, which occurs in a continuous expansion, ie in a continuous moving apart of the jaws A, just before the cross-cutting force decreases again and the Generalheifen are completely separated.
- the maximum cross-cutting force may be lower than 20 cN, for example 15 cN, 10 cN, 7 cN, 5 cN, 4 cN, 3 cN, 2 cN or 1 cN.
- the maximum cross-cutting force in a range of 0.5cN to less than 20cN the lower limit of 0.5 cN can be combined with the above upper limits.
- Other possible lower limits are 1cN, 1.5 cN, 2cN, 2.5cN.
- the separation behavior of the filter tow strip 10 can be determined by the number of binding filaments 13 in the connection region 11 between the two partial strips 12a, 12b.
- the detection of the binding filaments 13 takes place at the maximum of the transverse separating force, ie shortly before the complete separation of the two partial strips 12a, 12b, as in FIG fig. 1 shown.
- the binding filaments 13 are partly torn off and / or unhooked, the still crossed or connected filaments being detected shortly before the complete separation, ie at the cross-separation force maximum, for determining the separation behavior ,
- the connected or crossing filaments of the respective partial strips 12a, 12b are each regarded as a filament.
- the number of binding filaments 13 essentially corresponds to the number of crossing points 14.
- the connection marked I at the right end of the clamping jaws A comprises two filaments 13 interleaved with one another, which are regarded as a filament for determining the number of binding filaments 13 and have a point of intersection 14.
- compound II in which two filaments 13 are entangled and form a point of intersection 14.
- compound III four filaments 13 are connected together and form two crossing points 14.
- the compound III therefore comprises two binding filaments 13.
- the lower limit of the number of crossing points to a length of 20cm can be 1 crossing point. 2, 3, 4, 5, 6, 7, 8, 9, 10 crossing points are also possible as the lower limit.
- the filaments 13 may either be only looped, ie the individual filaments 13 form stitches or loops that mutually engage and form a connection.
- the filaments 13 can also only be hooked, wherein at least one filament 13 of a connecting filament pair forms a free end and into a loop or into another filament hook intervenes.
- a combination of entangled and entangled filaments 13 is possible.
- the connecting filaments form 13 crossing points 14, ie the opposing filaments 13 of the two partial strips 12a, 12b meet and cross each other.
- the invention also includes filter tow strips where in places the maximum cross-cutting force exceeds the upper limit of 20 cN, as long as this does not significantly affect the continuous operation of the filter rod machine processing the filter tow strip.
- the aforementioned tolerance of 95%, better still 99% has been found to be sufficient.
- the Twin Tow has a connection region which is such that 95% of the samples of a Twin Tows connect less than 50 transverse Ververende filaments to 20 at clamping length of the two tow halves or partial strips. Further, 99% of the samples of a twin tow may have less than 100 cross-herniated filaments on a 20 cm chuck length of the substrips 12a, 12b.
- the reference length of 20 cm of the Filter Tow strip section for measuring the maximum cross-cutting force can be chosen differently, for example longer.
- the maximum cross-cutting force with a longer reference section increases accordingly.
- the filter tow strip according to the embodiment of the invention in the connection region, i. in the region of low or low crosslink density 11 with respect to the cross-cutting force optimized.
- a force-extensometer with clamping devices is used, which is a pair of jaws having a clamping length of 20 cm.
- a 20 cm long filter tow is clamped in the longitudinal direction with the edges of the filter Tows in the jaw pair.
- the jaws A in the force-extensometer are slowly moved apart, so that the Twin Tow is first stretched. The required force is measured.
- the crossing crimped filaments of the fiber strand form a nonwoven structure.
- the dividing seam between the two twin tow halves opens.
- the open area is characterized by the number of cross-linked or cross-looped filaments that form, for example, a cross pattern.
- the jaws are further moved apart, with the cross-cutting force passes through a maximum at the point at which the filaments that hold the two tow halves together are maximally stretched. The number of cross-linked filaments is then detected.
- FIGS. 2a-2f different embodiments are shown in which the partial strips 12a, 12b of the filter tow strip 10 are arranged differently.
- the partial strips 12a, 12b are arranged side by side, wherein the connecting portion 11 and the partial strips 12a, 12b are arranged in a plane.
- the arrangement according to Fig. 2a For example, it can be made by crimping the two partial strips 12a, 12b together, whereby the crosslinking density in the connecting region 11 is adjusted so as to give a maximum transverse separating force of 20 cN.
- the two partial strips 12a, 12b are overlapping, ie arranged at least partially or completely overlapping.
- the connection of the two partial strips can be produced by mechanical needling or by needling by means of an air jet or a jet of water.
- the partial strips are arranged overlapping one another in the edge region.
- the partial strips 12a, 12b arranged completely overlapping one above the other, wherein the connecting filaments 13 formed as a common central track are.
- the connecting filaments 13 and the connecting portion 11 formed as an edge track are also possible, as in Fig.
- FIG. 2e shown to provide the connecting filaments 13 over the entire width of the overlapping partial strips 12a, 12b.
- Another way of connecting the two partial strips 12a, 12b is to arrange the connecting filaments 13 randomly distributed in the longitudinal direction of the partial strips, as in FIG Fig. 2f shown.
- FIGS. 3a-3c three embodiments are shown for double filter rod machines, each having two spreader nozzles 20a, 20b.
- the other machine parts that are usually present, for example, the stretching device, the spray device and the format part are not shown.
- the separating edge of the separating wedge 23 counter to the conveying direction of the filter tow strip 10, so that the filter tow strips 10 is divided by the separating edge.
- the guide rings 22a, 22b may be mounted so as to apply a normal force component to the partial strips 12a, 12b.
- the two spreader nozzles 20a, 20b can also be used as a separating device 21 in that the two spreader nozzles 20a, 20b are arranged so that their inlet openings do not line up, so that a normal force component is exerted on the partial strips 12a, 12b ( Fig. 3b ).
- the separation point of the filter tow strip 10 the spreader nozzles 20a, 20b upstream.
- the separating device 21 may be directly downstream of a force measuring device for measuring the voltage of the separated partial strips 12a, 12b in situ (not shown). Furthermore, a control device may be provided which acts in such a way that the conveying speed the individual partial strips 12a, 12b is regulated by means of the tension in the partial strips 12a, 12b.
- the crosslinking density in the connection region between the two partial strips 12a, 12b is set such that a maximum transverse separating force of the partial strips of 20 cN to a length of 20 cm or this force is not exceeded.
- This can be achieved, for example, by arranging the partial strips side by side side by side and crimping them together, the crosslinking density being controlled by the spacing of the partial strips from one another during crimping.
- the crosslinking density can also be controlled by mechanical needling or by needling by means of an air jet or a water jet, if the partial strips 12a, 12b are arranged partially or completely overlapping each other.
- the filter tow strip 10 can already be separated into partial strips 12a, 12b before the bale packaging, wherein the separated partial strips 12a, 12b are placed in different cans or in a divided can with several storage areas or in a single can. It is also possible to insert the undivided filter tow strip into a jug and pack it into a bale. In the latter case, the separation of the filter tow strip into the partial strips 12a, 12b takes place during the production of the filter rods, the maximum transverse separating force with which the filter tow strip 10 is divided not exceeding 20 cN over a length of 20 cm.
- a double filter rod machine is preferably used which has a separating device in front of the spreader nozzles, as in FIGS FIGS. 3a, 3b, 3c shown.
- a release force was measured at the predetermined tear line, ie in the range of the lower crosslinking density of 7-12 cN and in another example of 2.5-4 cN. These values relate to the lower and upper limits of the scatter of the measurement.
- a maximum cross-cutting force of 1cN - 10 cN, as well as 0.5 cN - 5 cN was measured.
- the number of connecting filaments or the number of crossing points was 2 - 20.
- the maximum cross-cutting force of 0.5 cN - 5 cN the number of connecting filaments or the number of crossing points was 1 - 10.
- the above values for the number the connecting filaments are the median (at most half of the observations in a sample have a value ⁇ m and at most half a value> m).
- the cross-cutting force and the number of connecting filaments can be adjusted, for example, as explained above, by a variation of the spacing of the partial strips in the crimping machine.
