An apparatus and associated method for forming a filter rod member of a smoking article, such as a cigarette, is presented. The apparatus comprises a rod forming unit configured to form a continuous supply of filter material into a continuous cylindrical rod member. An insertion unit is configured to insert the adsorbent material held by the carrier material into the rod member. The method includes forming a continuous feed of filter material into a continuous cylindrical rod member, and adsorbing material retained by the carrier material such that the adsorbing material is disposed within the rod member. Inserting into the rod member. And further comprising at least one filter segment (32) in which one or more composite fiber structures or degradable fibers are embedded, the composite fiber structure comprising carrier fibers and adsorbent fibers, wherein the adsorbent fibers However, cigarette filters containing adsorbents are also presented. |
