Filter tips are applied to cigarettes by a device equipped with a conveying roller ( 9 ) on which assemblies ( 4 ) composed of two cigarettes ( 5 ) and a double length filter plug ( 6 ) placed between them are united with tipping papers ( 11 ), also with a flexible rolling conveyor ( 12 ) looped around first and second pulleys ( 16, 18 ) and combining with the roller ( 9 ) to create a concave channel ( 13 ) along which a tipping paper is rolled around the relative filter. The rolling surface of the flexible conveyor ( 12 ) is faced with metal cleats ( 24 ) ordered transversely one beside the next. To ensure that the conveyor ( 12 ) runs concentrically with the roller ( 9 ) and maintain a constant depth along the channel ( 13 ), the device is equipped with magnets ( 30 ) and guide wheels ( 33 ) positioned on the side of the flexible conveyor ( 12 ) opposite from the channel ( 13 ) in such a way that the magnets ( 30 ) will interact with the cleats ( 24 ) and with blocks ( 26 ) and screws ( 27 ) by which the cleats are clamped to the conveyor ( 12 ). |
