- the mouth-side longitudinal segment 11 of filter 10 is a low retention segment made of a filter material such as Paper, crest or preferably cellulose acetate. It has a tensile resistance of about 10 to 15 mmWS.
- the middle longitudinal segment 12 of the filter 10 is again a paper filter plug, Crest or preferably cellulose acetate provided.
- the segment 12 has a high specific retention performance, so that even for the short middle Longitudinal segment 12 gives and has a retention rate of about 30% (unventilated) a tensile resistance of about 50 mmWS.
- this is the middle one Segment 12 the ventilated segment; with 18 ventilation openings are indicated.
- the ventilation openings 18 can be perforated online with laser beams, i.e. be made during the manufacturing process. But there is also Possibility to use pre-perforated covering paper for the filter.
- the ventilation openings ensure a degree of filter ventilation in the range of 50 to 85%, especially of 65%. They are preferably in the mouth-side direction of this middle one Segment 12
- the overall filter is of a filter covering 16, for example a filter paper, surround.
- the core element 15 of the coaxial segment 13 consists of cellulose acetate with a Retention performance of 65 to 95%, in particular of about 80%, based on one unventilated filter.
- the core element envelope 17 is essentially airtight.
- the jacket element 14 consists of cellulose acetate or others suitable materials with a low retention rate of 15 to 50% in particular of about 30%, based on the unventilated filter.
- the train resistance of the core element is greater than the tensile resistance of the jacket element 14 and lies at about 260 mmWS, while the tensile resistance of the matel element 14 is about 120 mmWS is.
