Definitions

  • the invention relates to a device for supplying a, preferably liquid, additive to a moving, spread web of filter material of the tobacco-processing industry by means of an applicator member. Furthermore, the invention relates to the use of a scraper element.
  • filter tow which consists mostly of cellulose acetate, withdrawn from a supply as an endless strip and treated.
  • the filter tow consists of a web of loosely adhering threads that are pulled apart to form a wide and mostly flat web so that the threads are moved side by side and substantially parallel.
  • the propagation of the web takes place in a spreader nozzle.
  • an additive which is usually liquid and consists for example of triacetin droplets, fed in finely divided form.
  • the Droplets dissolve the threads, so that the threads adhere permanently to each other after their summary to a round strand and wrapping with a filter paper strip in a filter rod machine, that are networked.
  • an additive consisting of a finely divided powdery substance can also be used.
  • Processing equipment of the type described above are in the patents US 5 060 664 and US 4 511 420 described.
  • EP-A-1 314 363 a filter manufacturing machine is disclosed wherein an additive is applied to a tow strip by means of spray nozzles.
  • Each spray nozzle is associated with a front cover and a rear cover, the rear cover having a plurality of openings. Between the rear and front cover of the tow strip is passed.
  • both the rear and the front cover are formed with a heater.
  • each wells are arranged to collect excess liquid.
  • This object is achieved in a device for supplying a, preferably liquid, additive to a moving, spread web of filter material of the tobacco-processing industry by means of a job organ in that at least one Scraper element arranged transversely to the direction of movement of the filter material is provided with a sliding surface aligned substantially parallel to the direction of movement of the filter material.
  • the sliding surface is designed in the manner of a groove in order to additionally collect and remove plasticizer not picked up by the filter material.
  • the stripping element in cross section is approximately L-shaped or T-shaped or U-shaped, wherein preferably a part of the formed shape is arranged as a sliding surface of the stripping substantially or approximately parallel to the direction of movement of the filter material.
  • the stripping element is designed in the manner of a channel to laterally divert, for example, collected in the gutter triacetin as a plasticizer above the funded filter material and lead to a reservoir for the plasticizer.
  • the position of the stripping element in the device is adjustable.
  • the device is formed closed, so that a housing is provided for the device in which the order of the additive takes place on the spread filter material.
  • the object is achieved by the use of a stripping element in a device for supplying a, preferably liquid, additive to a moving, spread web of filter material of the tobacco-processing industry by means of an applicator member, wherein the stripping element is arranged transversely to the direction of movement of the filter material and a essentially parallel to the direction of movement of the filter material having aligned sliding surface.
  • Fig. 1 a section of a device for spraying filter tow is shown in cross-section, wherein the device has a Abstreifblech 15.
  • the Abstreifblech 15 is hook-shaped or V-shaped or formed in the manner of a parabola.
  • the spread filter tow 20 is transported according to the marked conveying direction F over.
  • the filter tow 20 and the stripping plate 20 touch each other.
  • triacetin By applying triacetin to the filter tow 20, for example by means of an application nozzle or an application brush, which is not shown here, droplets of triacetin are applied to the filter tow 20. Due to the volatility of the triacetin droplets, the atmosphere in the spraying device ( Fig. 3 ) enriched with triacetin droplets.
  • Fig. 2a is a cross-section of an inventive Abstreifblech 15 is shown, which has at the lowest point a horizontal sliding surface 25 which is arranged parallel to the extended surface of the filter tow 20. By the horizontal continuation of the sliding surface 25, the dead zone (reference numeral 17, Fig. 1 ) avoided.
  • the flat sliding surface 25 has the effect of a guide for the filter tow 20 over the entire width of the filter tow 20. Furthermore, the sliding surface 25 has the effect of a spoiler, ie, at production speeds, the filter tow 20 is easily sucked against the bottom of the sliding surface 25, so that applied triacetin continuously through the tow 20 of the sliding surface 25th is stripped off. The accumulation of larger amounts of triacetin droplets in a dead zone (reference 17, Fig. 1 ) is prevented.
  • Fig. 2b shows a cross section of a further Abstreifblechs 15 according to the invention, in which the sliding surface 25 at the end of the sliding surface 25 as a boundary has a vertical wall 26. Through the vertical wall 26, the sliding surface 25 is also formed as a kind of groove for receiving and carrying away from the filter material or filter tow 20 not recorded or excess plasticizer.
  • a means 30 for applying a plasticizer, eg triacetin, to the deployed filter tow 20 is shown in a schematic cross-sectional view.
  • the filter tow 20 is transported according to the conveying direction F from right to left.
  • an application nozzle 31 is arranged, which generates a spray cone 32 with plasticizer droplets of triacetin.
  • a fine, mist-like atomization of a plasticizer, such as triacetin achieved.
  • the filter tow 20 is guided through lower stripping plates 33, 34 through the device 30.
  • the lower Abstreifbleche 33, 34 are arranged in the lower region of the device 30.
  • three Abstreifbleche 15 are arranged, which are provided with an approximately parallel to the direction of movement of the filter tow 20 aligned sliding surface 25.
  • a further Abstreifblech 16 is disposed above the filter tow 20, which has no sliding surface, as this Abstreifblech far away from the place of application of the plasticizer on the filter tow 20 in the device 30 is.
  • the stripping plates 15 are U-shaped or V-shaped in the filter-near area, so that a trough-like or groove-like depression is formed. In this groove-like depression, the softener droplets flying around and draining from the housing wall are collected in the upper region of the device and discharged laterally above the filter tow 20.
