Abstract
Filter cigarettes which are transported sideways at the periphery of a rotating drum-shaped conveyor are engaged by successive rolling surfaces of a pair of coaxial rotary rolling members which rotate at the peripheral speed of the conveyor but in the opposite direction so that the cigarettes are caused to roll about their respective axes and cease to advance with the conveyor. The periphery of the conveyor is formed with flutes which receive the freshly rolled cigarettes, and the rolling of cigarettes is abruptly terminated by arresting members which orbit adjacent the path of movement of the cigarettes at the peripheral speed of the conveyor and in the same direction. A laser is used to make holes in successive cigarettes while the cigarettes roll about their respective axes.
