Abstract (en)
[origin: EP1847185A1] The method involves unmixing fibers (12, 13) e.g. bi-component fibers and carbon fibers, of two different fiber types and accumulating the unmixed fibers. The fibers of finite length of two different fiber types are combined and mixed. The combined fibers are conveyed to a separating device by a flow of transport air (42). The combined and mixed fibers are separated by accelerating the fibers in a teasel and loosening the fibers, where the combining and mixing occurs directly before the separating process. A fiber web (41) is formed after the separating process. An independent claim is also included for a device for producing filter rods of the tobacco processing industry.
