Definitions

  • the invention relates to a device and a method for producing a hollow and wrapping material-free filter strand of the tobacco processing industry, the device comprising: a pressurized transport nozzle for conveying a filter tow strip through an inner space extending along a longitudinal direction in the transport nozzle, so that at an exit opening the transport nozzle a filter material flow is provided, a guide pin having a along the interior of the transport nozzle extending first portion, a downstream arranged in a transport direction of the filter material flow format unit comprising a format nozzle with a tapered in the transport direction transport channel, in which a second portion of the guide pin extends, wherein a surface of the transport channel together with a surface the second portion of the guide mandrel forms a format channel for forming the hollow and wrapping material-free filter strand, so that the filter strand inside has a cavity conditioned by the guide mandrel.
  • the invention also relates to a plant of the tobacco processing industry as well as a format unit and a guide mandrel for use in a device for producing a sheathing-free and hollow filter strand.
  • filter tow used as starting material consists e.g. predominantly cellulose acetate, to which a plasticizer, such as triacetin, is added before the filter tow is further processed into a filter strand.
  • the plasticizer dissolves the cellulose acetate fibers so that they stick together in a format unit by the action of pressure and heat, so that the filter material solidifies and the filter strand is formed.
  • the filter material stream in the format unit is treated with pressure and additionally with heat.
  • the necessary thermal energy can be introduced in different ways in the filter strand.
  • DE-A-103 54 797 a method is known in which the filter material with microwaves or hot air is applied.
  • a filter manufacturing machine according to EP-A-2 548 625 The acetate fibers are supplied with superheated steam in a format unit.

By injecting cold air into the filter strand, however, the residual moisture is forced into the filter strand.
  • the invention is based on the finding that with the aid of a non-stick coating provided on the guide surface of the format channel, the frictional resistance of the filter material flow during the production of the filter strand is significantly reduced. This is particularly advantageous for the production of the filter strand in a drawing process and allows an increase in the process speed.
  • a non-stick ceramic coating is used as the non-stick coating. Therefore, according to one embodiment, it is provided that such a ceramic non-stick coating is provided on the surface of the guide surface.

  • the spent process fluid so for example partially cooled superheated steam, sucked out of the filter strand, which has proven to be particularly effective.
  • the technical disadvantages occurring when blowing out the process fluid by means of compressed air also need not be accepted.
  • the problem that the moisture is forced into the strand when the process fluid is blown out by means of compressed air is overcome.
