Claims (14)

A device comprising a coating device (47) having a housing for applying a liquid additive to the strip (2), and processing the strip (2) made of a filter material of the tobacco processing industry along the conveying section for the strip (2) in the following the band (2) the coating apparatus (47) in the conveyance direction, at least one of the outflow region of the band (2) from the coating device (47), at least two suction openings of one suction device or A device characterized in that at least two suction devices of a plurality of suction devices are provided, and the band (2) is transported or can be transported between them. And after the band (2) the coating apparatus (47) in the conveyance direction, at least one of the outflow region of the band (2) from the coating device (47), the suction device is connected to Watakuzu separation chamber The apparatus of claim 1. Single or multiple suction apertures of the suction device according to claim 1 or 2, characterized in that has been found obliquely opposite the suction surface to the conveying direction of the band (2). A suction connection pipe (61, 62) with a respective formed suction opening (63, 64) is arranged next to the belt to be transported or transported, and the suction connection pipe (61, 62) 62) that are found toward at least one of the lower in the conveyance plane of the horizontal or in the band (2), or the suction connection pipe (61, 62) is linear, i.e., that it has been formed without bending The apparatus according to claim 1, wherein at least one is performed.   5. The suction connection pipe (61, 62) communicates with the common fluff separation chamber (72) on the negative pressure side or is connected to the common fluff separation chamber (72). The device described. Watakuzu separation chamber (72) must be connected suction side to the left by one of the first fluid separation chamber (75), Watakuzu separation chamber (72) and the first fluid separation chamber (75) separating wall (73 The device according to claim 5, characterized in that the first fluid separation chamber (75) is connected to the second fluid separation device (77). 7. The suction connection pipe (61, 62) is movably formed at that position, so that the distance between the two suction connection pipes (61, 62) can be adjusted. The device described in 1.   8. Ambient air, which has been sucked out and from which cotton dust (65) has been removed, can be delivered on the pressure side to the periphery of the device having the application device by means of a blower or is delivered. The device described in 1. In the method in which the strip (2) made of filter material of the tobacco processing industry is processed along the conveying section, and the additive is applied to the strip (2) by the coating device (47), the coating is applied after the additive is applied. After the outflow of the band (2) from the device (47), the cotton dust (65) or particles in the air around the band through the two suction openings (63, 64) from the periphery of the conveyed band (2) At least one of the above is sucked out, or at least one of the cotton dust (65) removed from the periphery of the conveyed belt (2) is separated in the cotton dust separation chamber (72). And how to.   10.
