Definitions
- the draw resistance of the finally to adjust the resulting filter as the amount of a filter material supplied through the filter Cropping the width of the layer filter material adjustable is.
- the method according to the invention is preferably a tobacco smoke filter made.
- the width of the layer is adjusted, is a variation of the filter production of one Filter with a given draw resistance to one Filter with another specified draw resistance without further and effectively possible.
- the Width of the position variably adjusted depending on draw resistance.
- the width of the strips in particular variable, adjusted.
- the width of the strips is a simplified adaptation of the widths of the format device supplied strip to the final cross-section the produced filter strand or the manufactured Filter possible, so that a more uniform Draw resistance over the entire cross-section of the filter is achievable.
- a particularly uniform draw resistance is given in particular, if preferred at least two strips of a different width exhibit.
- two strips each the same width.
- the material becomes filter material at least five stripes and max. 10 strips cut out or cut off.
- the filter material is a nonwoven and produced in particular by the air-laid method Service.
- carrier fleece fibers can be any fiber materials be used, such as cellulose, cellulose acetate, Regenerated cellulose, linters, etc.
- compounds, which are brought in the web to polymerize especially styrene proven, but also acrylic or Methacrylic acid esters, vinyl acetate, vinyl chloride, vinyl ethers and isobutylene.
- Fleece is referenced in particular to DE-AS 19 57 763.
- the invention is further characterized by a device for Production of a filter for tobacco processing products Industry with at least one first separator for cutting a layer of filter material in dissolved at least two strips of filter material, wherein at least one second separating element for separating the Location of filter material from a filter material supply is provided.
- the device according to the invention makes it possible to the amount to be provided for the desired draw resistance of the filter material, which joined together to form a filter strand is going to process in filters on.
- the position of the at least one first separating element for specifying the width of the filter material strips can be specified, in a simple way and way above the cross section of the produced Filters a uniform draw resistance are generated.
- the first and / or second separating elements are knives, in particular circular knives.
- the first and / or second separating elements comprise bundled electromagnetic waves of high energy density, such as, for example, laser beams.
- laser beams For this purpose, preferably excimer laser or CO 2 laser use.
- the format device comprises a first and / or a second pair of rollers, whereby a particularly simple embodiment of the invention Device is given.
- the first pair of rollers has a passage opening defined for the strips of material that the Design of superposed strips of material it is possible in a simple way, to arrange the strips of material in such a way that no cavity is created between these, the drag resistance could negatively influence.
- the second pair of rollers has a passage opening defined for the strips of material that round is a round one in a simple way Filter strand for further processing feasible.
- a particularly preferred embodiment of the present invention Invention is given when the filter material stock a bobbin is rotatable and drivable is stored. This purpose is served in particular by a motor which ensures that the withdrawal speed of the location of Filter material is constant, for which preferably the Speed of the motor is controlled or controlled.
- a filter for products the tobacco processing industry in particular a tobacco smoke filter, provided in particular according to one of the aforementioned methods has been produced, wherein a plurality of superimposed non-woven strips are provided.
- a substantially uniform draw resistance distributed over the cross section given the filter.
- the width of the strips is the cross section adapted to the filter to be produced, whereby a very uniform draw resistance is possible. If preferred the nonwoven strips parallel to a longitudinal axis of the Filters are arranged, the properties of the the filter thus produced hardly from those to distinguished, made from a cellulose acetate were.
- the web is by an air-laid method produced.
- the nonwoven strips are flat to each other and have substantially no cavity in between.
- Fig. 1 shows a plan view of an inventive Device for producing a tobacco smoke filter or a tobacco smoke filter strand.
- a fleece 13 wound up.
- the bobbin 10 On a bobbin 10 is a fleece 13 wound up.
- the bobbin 10 On the axis of rotation eleventh rotatably mounted.
- the bobbin is due to the low Tensile strength of a corresponding nonwoven fabric by means of a Motors rotated to pull off the fleece 13.
- the fleece is preferably produced by an air-laid method.
- the fleece 13 is guided past a pressure roller 14 and then by further circular knives 15 in, in this embodiment 6, fleece strip 16 cut. It can also have a different number of fleece strips 16 find use, such as 8 fleece strips.
- the nonwoven strips 16 each have a pair same width of, for example, twice 8 mm, twice 7 mm and twice 4 mm.
- the pair of two format rollers 18 is gem.
- Fig. 1 for example, a Format roller pair, which has a round passage opening defined, so that a filter strand 19 is formed, the has a round cross-section which is perpendicular to the longitudinal axis 24 of the filter strand 19 is arranged.
- Fig. 2 is a side view of another embodiment of the present invention.
- Fig. 2 corresponds essentially to a side view of the embodiment of Fig. 1, although the format rollers arranged on the far left in FIG. 2 18, through which a section B-B is indicated, in Fig. 1st not shown.
- counter bearing 20 designed as rollers or rollers are and serve as an abutment to circular knives 15, shown.
- the other elements correspond to the Elements of Fig. 1.
- the two indicated on the right Circles of the reel 10 show with respect to the larger diameter the part of the bobbin, of which no position yet was removed and with respect to the smaller diameter the part of the bobbin from which the layer fleece 13 deducted becomes.
- the dashed lines are simplified Representation of the nonwoven strip 16 with respect to their trajectory.
- Fig. 3 shows a format roller pair consisting of two Form rollers 18, which are about the axes of rotation 21 of Turn the format rollers 18. It is a groove 22 shown introducing six fleece strips 16 without significant deformation or force on the nonwoven strip 16 allows.
- Fig. 3 shows the in Fig. 2 shown format rollers in the section A-A.
- Fig. 4 is shown which is a cross-sectional view along the section line B-B of FIG. 2 represents.
- a groove 22 is provided, the is round. This results in a circular Passage surface of the adjoining format rollers.
- the nonwoven strips 16 preferably guided on the same length ways, superimposed and in the format of the filter rod machine introduced and then wrapped.
- the advantage of separating the web or layer of fleece from a reel or a reel lies in the possibility the draw resistance of the filter in a simple manner to vary. It does not have to for every draw resistance specification a separate bobbin with the appropriate width kept in stock. Depending on the desired Filter pull resistance can be the width of the Nonwoven web can be adjusted. Between the draw resistance and the set web width is a proportional But not necessarily must be linear.
- a bobbin change of, for example, cigarette paper usual are common Processes or devices used, such as these a bobbin change of, for example, cigarette paper usual are.
- the fleece is spliced accordingly or glued. It either finds a nonwoven storage Use or however two bobbins can at the same time operate.
