Abstract (en)
[origin: EP1584248A1] Filters for cigarettes are manufactured on a machine by which a web (15) of activated carbon fibre fabric is decoiled from a roll (18), fed into a fragmentation device (20) and broken up into filaments or particles. The fragments are gathered by a first unit (4) into a continuous flow (5) directed up and through the top outlet (39) of an ascent channel (38) into a further unit (6) with a slidable and air-permeable aspirating belt (40) such as will attract and retain the filaments or particles rising through the channel (38) and shape them progressively into a continuous stream (7) which is then released by the belt (40) to the infeed (45) of a unit (8) equipped with a forming beam (47) along which a strip (10) of paper is wrapped around the continuous stream (7) to form a continuous filter rod (9). Finally, the rod (9) is fed through a rotary cutter (14) and divided into sticks (13) that will provide the single filter plugs (54) for attachment to cigarettes (53). <IMAGE>
