It will under the term "order surface", in particular the Area of an (open) area understood within of which the additive passed on the area Filter material is applied. This is according to the invention provided that the size of this area predetermined and can be varied.
  • the variability of the application surface makes it possible to dose both the order quantity and the To reduce consumption of additive, since the excess of from the filter material not recorded additive is lowered.
  • the application surface in particular by means of at least a Abdeckelements, changed, so that, for example.
  • Method of covering a customization of the application surface to the desired order quantity and / or to the width of the filter material strip easy and is achieved quickly.
  • a dry filter removal can For example, by a complete closing or Abschotten the order surface are made. In this case the order area has the size zero.
  • filters without additive filters without additive. simultaneously the additive may be promoted, with the additive by the foreclosure not on the Filter material is applied.
  • the additive is evenly applied to the filter material applied when applied to the filter material Amount of additive per unit of time and / or per application surface is kept constant.
  • the adhesion between filter material and additive is reinforced when the filter material and / or the additive be charged with charge.
  • a uniform application of the additive to the Filter material is achieved in that the additive from at least one nozzle to at least one Side of the web is sprayed from filter material.
  • a plurality of nozzles are provided on one side.
  • the nozzles can be arranged in several rows become.
  • a homogenization of the order on the filter material is executed when the at least one nozzle with a constant pressure is applied. Through a consistent system pressure becomes an optimal droplet size and / or speed of the additive reached.
  • spray nozzles can the sprays in the form of spray cones or Cover sprayed sprinkles.
  • triacetin is added as an additive applied the filter material.
  • Triacetin has been added the production of filter rods as a suitable plasticizer and crosslinkers proven.
  • the task is also solved by a device of the aforementioned type, which further developed is that the additive over a job area can be fed and the size of the application surface adjustable is.
  • the application surface in particular by means of at least one cover, changeable.
  • At least one means for deriving and / or at least a collecting means for the filter material not added additive is provided.
  • the invention provides that at least a voltage source for charging the filter material and / or the additive with charge provided is.
  • At least one nozzle on at least one Side of the web of filter material provided.
  • a uniform application of the additive to the Filter material is particularly possible if the at least one nozzle can be acted upon by a constant pressure is.
  • Plasticizer from the At least one institution is allowed to exit Exit barrier provided.
  • Excess non-absorbed additive may be present in be returned to the institution if the agent designed for deriving as a band element.
  • the collection means for not recorded Additive as a scraping edge and / or as Formed basin.
