Definitions
- the activated carbon is introduced into the filter by doping the sheet-like starting material, in particular the paper, with activated carbon.
- Such doped paper filters include small particle size activated carbons which are bonded to the paper in the papermaking process. As a result of the process, the activated carbon is distributed over the entire filter volume.
- the additives can be applied by spraying and / or printing, in particular by inkjet, rotary printing or screen printing.
- Such processes which are known per se in connection with the production of print media, enable rapid and precise application of the various additives in spatially separate functions.
- the filter 1 thus produced thus comprises two spatially separated additives, which are in the radial direction of the filter body superimposed zones 3, 4, or layers present.
- the radially inwardly arranged zone 3 is covered by the radially outer zone 4.
- the additive-containing zones 3, 4 are, as shown in Fig. 2c, in the cigarette on the tobacco side and the additive-free zone 6 mund lake arranged.
