<p>An assembly (4) comprising two lengths of cigarette rod (5), a double length filter (6) and a band of gummed paper (7) is rolled up along a path describing a limited arc (8) to produce a double length filter tipped cigarette (9), passing between a cylindrical inner rolling surface (21) and a cylindrical outer conveying surface (46) which revolve in the same direction about respective axes (15, 24), the inner surface (21) at a greater velocity than the outer surface (46). The conveying surface (46) is generated by a succession of substantially flat faces (43), each affording a seat (49) shaped to accommodate a relative assembly (4) and incorporated laterally into one of a series of rockers (42) mounted so as to pivot between a first position, assumed along the rolling arc (8), in which the flat faces (43) are directed toward the rolling surface (21), and a second position assumed when passing through successive infeed and outfeed stations (3, 10), in which the flat faces (43) are directed away from the rolling surface. <IMAGE></p> |
