Definitions

  • the invention relates to a method for treating a filter tow strip during its continuous Querroughvermindemden gather within a guide channel, which is bounded by a together with a wrapping strip via a pulley, forming a bottom band and high-curved on both sides of the guide channel format tape to a filter tow line, which subsequently is wrapped with the wrapping strip to form a filter strand, are cut off from the filter rods, wherein during the gathering compressed air is blown into the filter cloth strip, the downstream in an air outlet zone through channels from the Raff Scheme emerges.
  • the invention also relates to an apparatus for treating a filter tow, comprising a guide channel having a cross-section for gathering the strip and having an inlet for supplying air under pressure and a downstream air outlet zone for discharging the air blown into the filter tow Guide channel limiting, forming a bottom band and on both sides of the guide channel arched high format tape and with a Deflection pulley, which feeds the format strip together with a wrapping strip to the guide channel.
  • filter tow is understood to mean a nonwoven made from a multiplicity of crimped synthetic staple fibers and / or filaments, which consists, for example, of cellulose acetate, staple fibers and / or filaments.
  • guide channel is understood to mean a channel designated as a "finger” in the art of filter production by means of a channel decreasing in the conveying direction for shirring the filter tow conveyed in the channel and reducing its cross-section until it has been introduced approximately as the strand cross-section.
  • upstream and downstream the conveying direction of the filter tow is assumed to be the "current”.
  • This object is achieved in accordance with a first aspect of the invention by a method for treating a filter tow during its continuous cross-de-crimping gathering within a guide channel bounded by a format tape fed together with a wrapper strip via a diverting pulley forming a bottom band and arched on both sides of the guide channel is, to a filter tow line, which is then wrapped to form a filter strand with the wrapping strip, are cut off from the filter rods, during the tearing compressed air is blown into the filter tow, the downstream exits in an air outlet zone through channels from the Raff Scheme, characterized that downstream of the air outlet zone, a further air flow is blown under pressure into the filter tow strip and exits through channels in a further downstream air outlet zone.
  • an apparatus for treating a filter tow having a guide channel decreasing in cross section to gather the strip, and an inlet for supplying pressurized air and a downstream air exit zone for discharging the air blown into the filter tow comprising, with a guide channel delimiting, a bottom band forming and on both sides of the guide channel highly curved format strip and with a deflection roller which supplies the format strip together with a wrapping strip the guide channel, characterized in that downstream of the air outlet zone, a further inlet for supplying air under Pressure in the guide channel and a further air outlet zone for discharging the air blown into the filter tow from the guide channel are provided.
  • the surprising advantage of the method and the device according to the invention is that the homogeneity of the filter rods is significantly improved, as the comparative photos of FIGS. 5 and 6 demonstrate. Preferred embodiments and advantageous developments of the invention are specified in the dependent claims.
  • FIG. 1 shows an arrangement of the applicant for the preparation of filter tow, which preferably consists of cellulose acetate, which is known under the name AF in the tobacco processing industry.
  • filter tow which preferably consists of cellulose acetate, which is known under the name AF in the tobacco processing industry.
  • a bale 1 of superimposed strips of filter tow of cellulose acetate is drawn from a driven roller pair 2, for example consisting of grooved roller and gegenpatentedder rubber roller, a strip 3, dissolved and spread by an air nozzle 4, passed over a roller 6 and another air nozzle. 7 further spread and relaxed.
  • a dragged, ie non-driven brake roller pair 8 keeps the formed web 9 of expanded threads of filter tow something back.
  • a so-called format device 20 connects, which has a guide channel 21 for the filter tow (hereinafter referred to as "finger") with decreasing cross section, so that the filter tow is continuously gathered in its promotion by cross-sectional constriction until it is about the Cross section of a filter rod required in the tobacco processing industry for the production of filter cigarettes.
  • the filter tow is pulled through the format device 20 by a so-called format strip 22, which is fed together with a wrapping strip 24 (eg paper strip) via a deflection roller 23.
  • the paper strip 24 glued to an edge is placed around the filter tow line and then a filter strand is formed in a known manner, not shown, from which the individual filter rods are cut off.
  • a filter strand is formed in a known manner, not shown, from which the individual filter rods are cut off.
  • the inlet part with the finger 21 is shown.
  • the other parts of a format device such as adhesive chamber and the like. are not shown, since they are not affected by the invention.
  • FIGS. 2 to 4 show a conveyor channel 21, also called "finger” in practice, which narrows in the direction of the arrow 19, that is, whose cross-section decreases continuously.
  • the filter tow is reduced in its cross section also, to about the thickness of the filter strand.
  • the format tape 22 is in FIG. 2 only shown schematically as a bottom band, although in reality it is arched on both sides of the finger 21 and thereby partially obscure the finger. This part of the format tape is therefore omitted.
  • compressed air is supplied with, for example, 3 bar, which flows through in the wall 27 in three rows attached slot-like channels 28 in the interior of the finger 21 and the moving through the filter tow.
  • the angle at which the air flows out of the wall 27 can be between 10 ° and 30 °, relative to the longitudinal axis of the finger, for example 20 °, so that the filter material receives a delivery component through the air.
  • the injected air can escape from the finger 21 through a sieve-like air outlet zone 29.
  • the outlet channels 31 in the outlet zone are the same size and have approximately circular shape in the embodiment with a diameter of about 0.5 to 1.5 mm, z. B. of about 1 mm.
  • the outlet channels may also have other shapes and dimensions.
  • Downstream of the air exit zone 29 is another air inlet 32 through which pressurized air of, for example, 2 bar is supplied, which flows through slit-like channels 33 mounted in the wall 27 in three rows into the interior of the finger 21 and the filter tow guided therein. Its fibers are re-entangled, which has a positive effect on the homogeneity of the filter rods produced.
  • the angle at which the air flows out of the wall 27 may also again be about 10 ° to 30 °, based on the finger longitudinal axis, for example, about 20 °.
  • the injected further air can escape from the finger 21 through a further downstream arranged sieve-like air outlet zone 34.
  • the outlet channels 36 may have the same shape and dimensions as the outlet channels 31. The relatively small dimensions of the outlet channels are advantageous because virtually no fibers from the filter tow pass to the outside.
  • the pressure of the supplied air may be higher or lower than the specified values.
  • FIG. 5 shows the distribution of filter tow in an opened filter rod used in a device according to the EP-B1-0269915 had been made. It can be seen that the distribution is non-uniform and has two bulbous thickenings 41, 42, between which there is a zone 43 with less material.
  • FIG. 6 shows the distribution of filter tow material in an opened filter rod made according to the invention.
