Abstract

In a process to manufacture cigarette filter tips from elongated extruded fibres, the essentially separated fibres (27) are transported by air towards a conveyer (32). The fibres agglomerate to form a group of fibres, each fibre being in partial point contact with adjacent fibres to form a non-woven fleece resting on the conveyer surface. The fleece is transferred to an outer wrapping strip and then is rolled to form a cylindrical wrapper around the fibres, simultaneously compressing the fibres into a filter. Also claimed is a commensurate manufacturing assembly.
