Cigarette sticks (5) are transferred from a cigarette maker (1) to a filter tip attachment (7) by a unit (9) that includes a conveying roller (12) made to rotate in a first feed direction (15) and furnished with channels (19) aligned on a second direction (13) transverse to the first direction. Each channel (19) accommodates a single stick (5), directed onto the roller by way of an impeller device (10), and presents two longitudinal areas (26, 27) designed to make contact progressively with corresponding longitudinal areas (28, 29) of the stick (5) as it advances into the channel (19), the effect being to create a chamber (30) between the stick (5) and the part of the channel (19) lying between the two longitudinal areas (26, 27) of contact, which is connected to a source (34) of negative pressure. <IMAGE> |
