Abstract (en)
The production rate when manufacturing cigarette filters can be increased by the open structure layer, positioned between the air-impervious layer and the tipping wrapper of the cigarette filter, to be made of threads of a textile or synthetic material filament with a diameter of at least about 0.1 mm. The equipment for bringing into practice the process can be provided with a control unit assuring the filter strand to be cut at a location at which a filling means layer is provided between the intersection and the next perforation.
