ABSTRACT:
An assembly including two lengths of cigarette rod, a double length filter and a band of gummed paper is rolled up along a path describing a limited arc to produce a double length filter tipped cigarette, passing between a cylindrical inner rolling surface and a cylindrical outer conveying surface that revolve in the same direction about respective axes, the inner surface at a greater velocity than the outer surface. The conveying surface is generated by a succession of substantially flat faces, each providing a seat shaped to accommodate a respective assembly and incorporated laterally into one of a series of rockers mounted so as to pivot between a first position, assumed along the rolling arc, in which the flat faces are directed toward the rolling surface, and a second position assumed when passing through successive infeed and outfeed stations, in which the flat faces are directed away from the rolling surface.
